Rajarambapu Institute of Technology was established in the year 1983 with a few branches in engineering among which was the automobile branch, being the first institute in western Maharashtra to start with automobile trade. The institute is certified with ISO 9001:2000 standard for the year 2008-2011and also accredited by NBA, AICTE, New Delhi and the Institution of Engineers (India), Kolkata.

SAE RIT Collegiate Club was implemented in the year 2003 with a vision to inculcate among the students the awareness and knowledge of the very rapidly growing automobile sector in India. SAE RIT Chapter since then has taken many initiatives such as organizing seminars, ARAI visits, technical symposium, etc. This has brought awareness and motivation among the students towards the automobile field.

Participating and being shortlisted for SAE BAJA ’09 was really a big dream come true for all the automobile and mechanical maniacs in RIT. Fourteen budding engineers have struggled and worked very passionately to make this event as a success, occasionally facilitated by the institute.

After the registration for BAJA, the team had built a plan and empowered the team members by allocating and making the individuals responsible for their roles. The activities had been split into various systems viz. suspension, braking, chassis, etc.

Performance of the team members and their activities was apprised time to time by the team leader. The team worked within the boundaries set by the SAE India BAJA rules. In spite having constraints such as sponsorship, rural locality where the institute resides and the facilities available at the location, made the team further innovative.

Team members went on a search for spares, parts and managed within their budget. The team went one step ahead where they designed and machined some of the parts such as hub, disc brakes, driver’s seat. Apart from knowledge and skill contributions made by the team, the expenses incurred have been contributed too by the members.

All the team members were proud of this accomplishment and were fully satisfied with the technical knowledge gained.

Specification of their car

The team strictly followed an actionable plan with established targets to build the perfect ATV keeping the five basic design parameters namely durability, acceleration, traction, maneuverability and speed in mind. Most of the components were designed and manufactured to complement an ATV weighing 320kgs as the market catered to cars weighing above 1000kgs only. External front swing arms and rear trailing arms were designed to enhance rider comfort through increased suspension travel. ATV tyres were selected to achieve better traction while a chain drive ensured maximum torque output without sacrificing on the vehicle top speed.

Since the vehicle is very light in weight, thus using a rack and pinion system would be the cheapest and the best option.  We have come up with an innovative self designed steering geometry which would solve the purpose of effective steering and would be compatible with our design of the front suspension system. This new system would have all linkages from the outside of the wheels instead of inside as done in ordinary steering systems. Also to minimize the lateral stresses in the steering links we decided to use cables in place of rigid links to steer the vehicle. Incorporation of a 4 discs along with a cross-linked brake circuit resulted into an efficient, durable and safe ATV.

Steps adopted for the sake of weight reduction

A considerable weight reduction was achieved through good designs and optimum pipe selection for the roll cage. The steel tubes for the Roll Cage were decided after several iterations were performed to select a tube with outside diameter and wall thickness that would yield in best possible weight reduction. Majority of the components like the hubs, knuckles, swing arms, wheel axles, etc were designed and manufactured to reduce the maximum weight without decreasing the strength. The efforts made by the team to improve every single system on the ATV resulted into an extremely safe, light and durable vehicle weighing only 250kgs.

Special features of our vehicle

Design of all the components have been tested for their structural strength, bending stiffness, torsion stiffness, etc. according to the requirement of the systems. We have coupled meticulous research augmented by extensive calculations with out-of-the box thinking which has propelled several innovations. Innovative external front swing arms and rear trailing arms result in increased driver comfort. An exhaust system with a catalytic converter will effectively control and reduce noise and air pollution.  The design of the roll cage, adequate clearances, body works and safety features of the ATV would surely help us in garnering some additional points.

Sponsorship details

The ultimate goal of CITM is the success of its students and it’s because of this goal that it has readily agreed to sponsor its first ever BAJA SAE INDIA team. CITM has extended full support to us students, so that we can pursue our goal of participation in this event without any obstacles.

Ford GARUDA – Vehicle No. 11 sponsored by FORD INDIA

Dr. M.G.R. Educational & Research Institute, Chennai – 600 095

With the immense team spirit and faith, gained working together since BAJA’07, team Ford GARUDA of Dr. M.G.R. Educational & Research Institute, Chennai believes it can come out with flying colors in BAJA’09. Our strategy has been moving around proven facts, specifications given, and involves in it the discipline and hard work of our team. The faith in our abilities, the ambition and inherent auto-passion in each member has yet again brought us together not just to be a part of the competition but to win it.  Thirteen member team comprises of ten final year while three pre-final year mechanical engineering students.

The team

Final Year-
Anshuman Vagesh (Captain), Deenbandhu Prasad, Lokesh Kumar, Madhav Kishore, Mobin Joseph, Naman Dugar, Navjot Jain, Nikhil Anand, Pritish Shubham, Umesh Raghuwanshi.

Pre-final Year-
Ashish Kumar, Auroashish Mohanty, Praveen Anand.

The team is lucky to have the support of college in general and the staffs of mechanical department in particular. Prof. L. Vincent Paul is the visiting faculty advisor of the team.

The Baja prototype that the Ford GARUDA intends to bring out for the 2009 event is a result of extensive design and analysis cycles, a concurrent engineering approach as well as an attempt to outperform the benchmarks established. The vehicle is way ahead than the last year one in all the departments. The techniques of design for manufacture and assembly (DFMA), fault analysis techniques like rigorous brainstorming sessions and periodic reviews were the major modus operandi of the team.

Identifying the limitations and coming hard on them sets Ford GARUDA apart from others.

The compact, light and formidable built of the vehicle is expected to cater to the punishments offered by the track and at the same time providing optimum drivers’ comfort and safety. The main focus has been the suspension system. An impressive mutual compatibility of suspension, steering and wheel assembly adds to its unique features. An adjustable drive ratio is another one. Moreover, the ATV is equipped with all drivers’ safety gears. A detailed look follows as under -

Suspension
Fully independent and unequal non-parallel A-arm suspension (both rear and front) with accurately determined hard points on packaged wheel assembly determines the impeccable vehicle stability and control. The provision for adjustable geometrical parameters offers the best bet for required directional stability. The static ride height of the vehicle is 9-10 inches as desired. Readymade coil over shocks has been used against gas shocks or custom made ones for their reliability.

Steering
Self-fabricated direct linkage tiller (handle bar type) steering have been designed and incorporated in the vehicle. The clutch and gear arrangement rests on the steering handle while others are foot-operated as per the regulations. It has been tried to achieve a lower steering ratio and as tight of turning radius as possible to perform well in maneuverability competition. Moreover, design aims at eliminating the bump steer as much as possible.

Brakes
A hydraulic braking system with a single-foot mechanism increases the safety and maneuverability of the vehicle by locking all four wheels in a time of about one-third of a second. Double piston light weight calipers are powered by a tandem master cylinder. Tandem master cylinder increases safety by incorporating dual redundancy as well as for SAE rules compliance. Perforated disc brakes dissipate heat more readily and are light. Two standard red brake lights have been used which are independent of kill switch circuitry.

Tires
The tire configuration for front and rear are 21*7-10 & 22*8-10 respectively. The light weight ATV tires have aggressive tread to perform well in loose dirt, dry as well as muddy conditions by offering higher traction. With a sporty look it has enough rim size to accommodate the brake assembly.

Weight Reduction
The self-fabricated parts like uprights, spindles and Al-hubs, handle bar steering system, eliminating the non-necessary chassis linkages/flanges and clinically tailored parts has led us limit the weight of the vehicle as low as 255kg. Light weight seats and tires, use of Aluminium sheet metal for the cover (against Mild Steel), perforated disc brakes and small, compact roll cage are the other factors in weight reduction.

Vehicle dynamics has been a special concern throughout the process of design, manufacturing and testing/validation. This along with the serviceability, physical appeal and robustness are the other qualities that make it stand out of the folk.

Ford India Pvt. Ltd. is the team sponsor

Ford Motor Company is the world’s fourth largest auto maker based on worldwide vehicle sales. It has been manufacturing, designing and engineering vehicles for more than 100 years now. Actively participating in an event like this, Ford is helping build a strong foundation of human resources in India. Efforts made by the company, helping many prospective engineers and other developing students to learn from hands-on experience and to grow from one of the most exciting and educational opportunities of their lifetime is highly commendable.

Message

SAEINDIA has given a very good platform for all the Indian engineering students to showcase their talent by promoting this creative learning in the form of BAJA. We sincerely expect other teams to understand this and cash in the opportunity, in earnest, by participating in it with full zeal giving tougher competition to each other and taking the competition to the height that has yet not been attained anywhere else by the Baja maniacs. In short, let us make India the ultimate BAJA destination.

IAB Comment- Guys, we regret for keeping you waiting as a few of the other teams are yet to reply (an email from the Baja Authorities has been dispatched to those who haven’t participated) and henceforth we decided to defer the original schedule.

After reading your write up, we find the handle bar type steering very unique and an interesting concept. None of the other teams in our knowledge have adopted this type.

Although your driver looks funny in orange (Pathetic fashion statement, we must say;)), he should be in a very strong position to take the team to pole with such a competitive and well-engineered car. We wish Team Ford Garuda all the very best. We feel the Baja fort can be captured very easily with a car like theirs.

‘The Techie Tyros’ is an enthusiast group of seventeen individuals endeavoring to enhance and refine the aspect of practical engineering through hours of hands on work outside the classroom. It is one of the fifty nine teams selected for JK TYRE SAE BAJA INDIA 2009 competition.

The team represents ‘The Institute of Technology and Management, Gurgaon’ registered under ‘Maharishi Dayanand University, Rohtak’ It is a prime and the most sought after technical institute in Haryana. After proving its capability and mettle in MINI BAJA 2007 the college does not wish to rest but keep going which has always been the best feature of this institute. It plans to mix the right kind of talent, passion, vision and innovation to reach the pinnacles and then continue to redefine them. The college has always been inclined towards creating opportunities for students to develop competencies and skills at par with the growing standards around the globe.

The team is fortunate to have the able leadership of our team captain Raman Sarin and the never ending support of our faculty advisor by choice Mr. Ashwini Sharma. The seventeen members of the team are very much active so we have the privilege of having seventeen new ideas daily. We also have the infinite support of our entire Mechanical and Automobile Department and also of the college management.

SPECIFICATIONS OF THE CAR

The vehicle we are making is an All Terrain Vehicle (ATV). It is a rear engine rear wheel drive meant for off road driving purposes like golf carting, adventure sports, warships, mining etc. Our ATV is single seated powered by the LGA 340 cc engine sponsored to us by LOMBARDINI. The gearbox is a four forward and one reverse with in built differential sponsored by MAHINDRA & MAHINDRA. The other specifications are listed below.

ROLL CAGE

• Made out of IS 1239 Part 1 heavy duty pipe having a yield strength of about 480 Mpa which is much above the stated requirement of 370 Mpa.

• Designed so as to ensure maximum safety to the driver. The length of various members has been kept small so as to have maximum strength and rigidity.

• MIG welding and not Arc welding has been used to weld the roll cage. This again keeps the roll cage high on strength and rigidity. It has been made in a very compact manner so as to keep easy accessibility to controls and to ensure a better balanced car.

TIRES

• The front tires have an outer diameter of 21 inches, rim diameter of 10 inches and 8 inches of tread width. They are 6 plied tires having a tread height of about 5.5 inches.

• The rear tires have to provide the drive hence they are having an outer diameter of 22 inches, rim diameter is 10 inches and tread width is 11 inches. They are also 6 plied having a tread height of about 6 inches.

• Due to these specifications these tires provide very good traction and thus transfer good amount of torque. Built with 6 plies and reinforced casing these are one the most puncture resistant tires in the market today.

• Large shoulder knobs wrap down the sidewall to provide excellent side to the pullout of the ruts without causing sidewall failure. Smaller tires in the front result in better steering control. The deep tread and open wing design provides excellent clean out with each lug and improved traction.

SUSPENSION

• We are using equal wishbone suspension for both front and rear. This gives more movement to the tires as compared to the conventional Mac Pherson Strut for the same spring compression. It is an independent suspension system.

• With this type of suspension system there is a better distribution of forces on the roll cage.It can be slightly adjusted for the different suspension parameters like camber angle, ground clearance etc during testing and then finalized.

BRAKES

• We are using disc brakes in all the four tires. This gives us the advantage of the ability to lock all the four tires at the same time which is a requirement according to the rulebook.

• The material of the disc has a better friction material so we have more coefficient of friction. We are using X type lining in the brakes to ensure efficient and reliable functioning of the brakes. The disc is a multi hole one so the heat dissipation is very high.

STEERING

• We are using a customized rack and pinion steering. It has a steering ratio of 19.8:1 and a turning radius of 9.5 feet. The steering is fitted with a removable steering wheel for the easy and comfortable exit of the driver.

• Also by using customized rack and pinion steering we have been able to reduce the weight as the conventional recirculating ball type steering weighs a lot.

AESTHETICS & ERGONOMICS

• Our car is physically appealing. Sharp edges have been avoided and body has more curves then sharp turns.

• The controls have been intelligently placed.The controls are accessible and convenient to use.

STEPS ADOPTED FOR WEIGHT REDUCTION

• We have used Aluminum in the tire hubs. The number of members in the roll cage has been reduced.The length of the members has been kept less so as to increase strength and reduce the unnecessary weight at the same time.

• We have used Aluminum sheets for flooring etc rather than the conventional GI sheets. We are using fiber sheets at places which will not face the impact to reduce the weight.We have used customized rack and pinion steering rather than the recirculating ball type as the latter is much heavier.

THE UNIQUE SELLING POINTS

• It is a very safe vehicle. The roll cage is very rugged and sturdy and would under all circumstances ensure maximum safety to the driver.

• Maximum standardization of the parts has been ensured for increased replace ability and less maintenance cost.

• Maximum use of bolts has been made so as to ensure maximum serviceability. The steering wheel is removable so that the driver can make an exit very comfortably. The controls are accessible and convenient to use.

• A special arrangement has been made for things like fire extinguisher, tool kit etc

A team of seventeen members ‘THE TECHIE TYROS’ from our college decided to take part in it. The team got selected amongst the final 27 teams to design and manufacture an ATV. The college being relatively unknown for its mettle in automobile engineering took this opportunity as a challenge and decided to cash in upon it. The result showed the amount of sincere work put into the project as we ended up at an overall rank of 10th and 2nd in North India behind only PEC Chandigarh leaving behind the big guns like IIT Delhi, DCE Delhi and NSIT.

MESSAGE TO THE OTHER TEAMS

This is a great opportunity for all of us and as there is no security but only opportunity we must grab it with
both hands and make the most out of it. We are all diseased by the same automobile bug that is why we are all here so it is more or less a dream we are working for.

It is said that when you wake up in the morning you have two choices. Either you continue your dream in the bed, or you can get up and make your dream come true.
So let us all just step out and work. We should not look upon each other as competition and threat but as a team of sixty colleges looking to place India on the global map not just for manufacturing but also for designing.

So let us just go all out for the event and enjoy it. Best of luck to all teams from our side and looking forward to meet all the technocrats.

With inputs from the team

Designing and manufacturing an all-terrain vehicle is an immensely thought provoking and mind boggling task. Moreover, the number of students entering into the field of automobiles is continuously dwindling. As far as women are concerned, most of them still refrain from opting into this field considering it tough and out of their reach.

However, participating in such an event as an ALL GIRLS’ TEAM is a great high in itself. It also serves as an
important initiative in this field.With best intentions in mind, we would like to bring a positive change in such a mindset of the society. This would be a great energy boosters for young enthusiasts like us and hence we have decided to accept this challenge and dedicate our energies towards making our dream of designing and manufacturing a one of its kind vehicle, a reality.
We are starting from level zero and learn till the completion of the task. Our marketing skills, sportsmanship and team spirit as well as our ability to endure sheer pressure within the given time frame have developed during the course of this event.

The success of this project would change the vision of the feminist section of the society and also inspire millions to step out and do something different for themselves and contribute their level best to the mechanical and automation field.

Maruti Suzuki India Limited, India’s largest Auto manufacturer is the official sponsor of Team El Conquistador

Following are the specifications of our vehicle:

TYRES

In the beginning, we zeroed upon the tyres suitable for a terrain like ours. We chose tyres with stiffer sidewalls and bigger tread block patterns that suffice to the needs of an all terrain vehicle as they serve the purpose of gripping the dirt well.
Dimensions chosen for this purpose are-
21* 7 *10 – Front
22*11*10 – Rear

SUSPENSION SYSTEM

A good suspension is vital to the performance of an off-road vehicle.
The suspension must keep the tyres on the ground at all times to ensure optimum traction and grip as the vehicle transverses rough terrain. The main goal of our team was to have a simple and light weight suspension system with an optimum wheel travel and shock absorbing and which is compatible with the steering and easily adjustable at the same time. Keeping in mind all these things, unequal A-arms were used in the front and rear that give good control over the wheel angles.

STEERING SYSTEM

The purpose of the steering system is to direct the wheels in response to the driver inputs and hence provide directional control over the vehicle. Along with simplicity in design and light weight, the main concern was quick steering response. Due to these factors, rack and pinion steering arrangement following the Ackerman geometry was used.

BRAKES

Objective of brakes is to slow or stop the motion of a vehicle and to keep it from starting again. Outboard brakes were incorporated due to their better heat dissipation and better directional stability. Our main concern was to lock the wheels together and not compromise with the driver’s safety.
Disc brakes on all the 4 wheels is used. For the sake of weight reduction, the material used for the fabrication of chassis was such that it has high yield strength and low weight.

An FEA (Finite Element Analysis) of the chassis was done to optimise the weight and strength of the chassis.
Fibre seat is used that further reduces weight.
Suspension arms were made triangular in shape instead of a ‘U’ shape inorder to reduce weight.

The thing that makes our vehicle stand out from the rest of the vehicles is that extra care has been taken in the designing phase itself to ensure that vehicle is fabricated only after completely designing the various subsystems and testing them. Also, our vehicle has undergone a month of rigorous testing thereby giving us enough time for modifications and fine tuning along with rectifying the problems faced before the actual race!

“Winning isn’t everything…it’s the only thing…”

This is what Team El Conquistador strongly believes in and are working towards..
Our primary goal is to abide by all the regulations set forth by SAE and to build a vehicle that will trek through outdoor terrain with ease and will endure the four hour long endurance race. We are confident of posing a tough competition for the rest of the teams and hopeful of emerging victorious!

IAB Comment- Watch out guys!

Lets not forget these guys were winners of the inaugural Baja SAE India 2007 event held between 21st-23rd Dec 2007. So, a lot is expected of them who will be working their guts out to retain their trophy. Here are the details of their vehicle for 2009

What  do  you  think  will  make  your  vehicle  stand  out  from  others?

The comfort of the driver. Large cockpit space, silky smooth steering and a well-designed suspension system ensure that the driver has a relatively comfortable ride on even the roughest of terrains.

Sponsorship

With the kind of effort we have put in for this competition, we are pretty sure that Team mechISMU’s vehicle will stand out as one of the best.

We are still not taken. Any corporate organization interested in adopting Team mechISMU should feel free to contact us at mechISMU.ism@bajasaeindia.org.

What  do  you  want  to  tell  other  teams  which  are  participating  in  this  contest?

We are a bunch of “race-ists” who have put out heart, soul and brain into this project. We have prepared, persevered, practiced and we are sure we’ll perform. Hope we have one hell of a race out there and may the best buggy win.

IAB Comment- The vehicle looks raw and rugged. The white, red and black paint combo makes this one desirable off-roader. The large steering wheel and seat will keep the driver in good shape even on a long drive. Notice the well optimized front wheel geometry? Must have been done to strike the best balance between steering through tight corners with ease and maximum straight line stability.

The large coil springs at the rear should make it ride like a dream even over the worst of terrains and while at rest, makes the vehicle the roar with confidence. Overall the vehicle looks complete and a job well done. Best of luck.

IAB Recommendation- Treat the wheels with a splash of black, and a couple centimeters of white paint along its circumference.

We wish to thank mechISMU from ISM University, Dhanbad for their participation on Indian Autos Blog.

Weight Reduction:

Extensive use of custom designed and manufactured parts – hubs, uprights, springs, etc. Advanced Finite Element Analysis for various parts ensures that the parts are not overdesigned. Data from the Data Acquisition System is used to refine estimations of the forces on various parts of the vehicle – improving the Finite Element Analysis. Smart packaging in smaller wheels reduces unsprung mass substantially

Baja SAE India gives us exactly what we need-A stage to showcase our talent and put our knowledge to the test competing with the finest others in India. The meticulous planning required for the event requires a high level of team work and cooperation. The competition gives us the opportunity to gain practical/working knowledge of such a complex machine.

In its rookie year at the event, IIT Bombay Racing plans to demonstrate the immense multidimensional capabilities of our car and finish in the top three teams. We then plan to take part in competitions at the international level.

Details of Team Sponsor-Jaypee Group

The Jaypee Group is a well diversified infrastructural industrial conglomerate in India. Over the decades it has maintained its salience with leadership in its chosen line of businesses – Engineering and Construction, Cement, Private Hydropower, Hospitality, Real Estate Development, Expressways and Highways. The group has been discharging its responsibilities to the satisfaction of all its shareholders and fellow Indians, summed by its guiding philosophy of “Growth with a Human Face”

IIT Bombay is one of the premiers engineering institutes of the world where the best brains of the country gather to become world class engineers of tomorrow. With an esteemed faculty that inculcates innovative and logical thinking to shape the finest brains, we have taken up the challenge posed by Baja SAE India to prove our worthiness.

IAB Comment- IITians bring honor and accolades to India. They project India to the world as a country with bright brains and immense strength.

IIT Bombay Racing has got a very competitive vehicle, and it seems to me like they have kept is simple (Or are you guys not disclosing the complicated details?). The ingress and egress should be very easy with such a wide and tall entry area (speaking with input from the photograph), but body roll might be an issue, which the custom made springs and dampers should take care of, hopefully.

We wish them success in the competition. Thank you so much for participating on IAB.

BITS Pilani’s Team Inspired Karters is geared up for BAJA 09. The team started its preparation for BAJA 09 in February with the team members of BAJA 07 orienting the new team members with the different aspects of vehicle designing and fabrication.

The team is divided into different areas of sponsorship and marketing, suspension design, steering design, chassis fabrication, powertrain and braking system.

The 15 team members making up the team comprise of students drawn from various disciplines- mechanical, civil and electronics and electrical engineering. This multi disciplinary structure aims at gaining input from all branches as the process of making a vehicle is not in isolation of any particular discipline.

“ Our team members not only have knowledge on engineering subjects but also on finances and economics which we have gained through the electives offered in our curriculum. The wide range of subjects cover all the aspects from designing, cost optimizing to marketing a vehicle, thus effectively mirroring the process by any automobile company while introducing a new vehicle in the market”, comments the Team Leader Abhimanyu Shirwalkar.

The team also has the responsibility of matching up to the expectations that come with the country’s best private engineering college. Unfazed by this, they believe that working on the basics along with disciplined work is the way to success.

BAJA 09 holds tremendous importance as many of the team members are keen to join the booming automobile industry in India. They want to be a part of the endeavor to make India one of the top 5 automobile production countries in the world. (Hats off, that’s the spirit we’re looking for)

The focus of the team has always been in working out a design and then manufacturing the components in the BITS workshop or customizing the components of commercial vehicles according to their needs. This is against the conventional approach of working out the vehicle design against standard available products , which reduces innovativeness. In pursuit of making every part as their need, the team members have had to endure numerous 12 hour trips to Delhi and Jaipur.

“ The students have worked tirelessly throughout the year. The customized hub fabrication in Computerized Numerical Control (CNC) is probably a first for any team in India”, says the professor in charge, Mr Amit Kumar Singh.

The team name , Inspired Karters, draws inspiration from the herculean effort of making a vehicle in a resource scant place like Pilani. They believe in the motto-“ Inspiration breeds motivation which leads to success”

Their ATV has a ground clearance of 18 inches which allows the roll center and the center of gravity to coincide, thereby providing the excellent vehicle stability. ITP mudlite tires , popular with BAJA teams abroad, have been imported from USA.

The steering system used is of the sports car, Lotus Elise (Awesome Guys!! . The vehicle chassis is light in weight with Aluminium being used as the body covering material.

The gear ratio of 40 mm/rev is much higher than those available in Indian cars. This provides the driver with more a sensitive steering, very essential for an All Terrain Vehicle.

Team Inspired Karters look forward to succeeding in BAJA 09 and brining laurels to BITS Pilani.

IAB Comment- Well said. These guys have what we call a paper tiger. The specifications add up to something colossal on paper, but will it work in reality? We hope these guys are testing and logging even the intricate  data, because if they can go with a car that can last for the entire competition’s duration, they might come back with the trophy!

But that’s just what we think. We wish you luck and prosperity and thank you for participating on Indian Autos Blog.

Note to all the other teams- Please try and answer all the questions we have sent you in the questionnaire.
