TeamKART is a group of students from IIT Kharagpur who like to explore the practical side of automotive engineering.TeamKART is officially a sponsored research project under the Sponsored Research and Industrial Consultancy Cell (SRIC) and the Department of Mechanical Engineering, IIT Kharagpur. The team designs, fabricates, manufactures and tests Formula prototype race cars and represents IIT Kharagpur at Formula Student, UK and Formula Student, India.

History[edit | edit source]

Its foundation was laid in 2008. It was an outcome of efforts of a few enthusiastic founding members and faculty advisers. The team took a solid form with the support of Prof. PP Chakraborty (present Director, IIT Kharagpur) and Prof. Sunando Dasgupta (present Dean SRIC, IIT Kharagpur). Sidhartha Khastgir became the first Team Leader and stirred the team through the difficult initial stages where the team faced shortage of funds and technical knowledge. Since then it has grown to become IIT Kharagpur’s largest student project encompassing around 70 students from 10 different departments. Ganesh Kumar M. became the second team leader and held responsibility for three years and oversaw the development of K-1 and K-2. Till date the team has successfully made three cars- the KX-1, the K-1 & the K-2. K-2 competed at Formula Student UK 2013. Several design oversights in K2 were fixed in K-2.2 by a new chassis and intake-exhaust system; which competed at Formula Design Challenge 2015 (FSI 15).

Formula Student[edit | edit source]

Formula Student is Europe's most established educational motorsport competition, run by the Institution of Mechanical Engineers(IMechE). Universities from across the globe are challenged to design and build a single-seat racing car in order to compete in static and dynamic events, which demonstrate their understanding and test the performance of the vehicle. The format of the event is such that it provides an ideal opportunity for the students to demonstrate and improve their capabilities to deliver a complex and integrated product in the demanding environment of a motorsport competition.

Cars[edit | edit source]

KX-1[edit | edit source]

The KX-1 was the team's first effort to build a car. The X' in the name stands for experiment as the car was the very first attempt of the completely novice team. The car was powered by a Honda CBR600RR engine which has hence forth powered all the cars till K-2.2.

KX-1

The team participated at Formula Student, UK 2010. The participation was however limited to static events. The team stood 9th in the cost report analysis, as the car was very cost effective in its design. The team was one of the six teams to be nominated for Ahe irbus Teamwork Award.

K-1[edit | edit source]

The K-1 was a major leap forward for the team. It was improved manifold from the first car. The car was powered by a Honda CBR600RR engine just like its predecessor. The team participated at Formula Student, UK 2011 with the car. However the team was restricted to participate only in the static events as the car had failed to clear the stringent scrutiny tests before the dynamic events. The team's impressive performance in the static events saw the team becoming one of the top three rookie teams at the event. The team again became one of the six teams to be nominated for the Airbus Teamwork Award.

K-2[edit | edit source]

With a new car, theK-2, the team participated at Formula Student, UK 2013. The car was powered by a Honda CBR600RR engine just like its predecessors. There was significant improvement in the car, a new plenum had been designed and manufactured in-house in rapid prototyping for better intake. New and more efficient SLA suspensions were implemented. It was the team's most successful visit yet with the team clearing all the six scrutinizing inspections namely Tech, Safety, Chassis, Noise, Brake and Tilt, as per the rules & norms governed by the MSA (Motor Sport Association) and SAE (Society of Automotive Engineers). Out of the six Indian teams, TeamKART was one of the two teams to qualify for the dynamic events. The team competed in the endurance test. The team managed to secure 43rd position in Business Presentation and 45th in Cost and Sustainability Design Report and stood 67th overall among 120 participating teams.

K-2.2[edit | edit source]

The K-2.2 was the upgraded and improved version of K2. The car was powered by a Honda CBR 600RR engine. A consequential improvement could be seen in the car. A new impact attenuator was added and the intake diffuser, throttle body and air filter had been changed. A new Scorpion Carbon fibre muffler, which was the first carbon fibre part of the car was also introduced. The size of the radiator fan had also been increased for better performance. The team participated in Formula Design Challenge 2015 and passed technical scrutiny. Although a seized engine prevented the team from taking part in the dynamic events nonetheless it was a great learning experience for the whole team. The team bagged the first runners up position in both, the Business Presentation and the Cost Report.

TERMINOLOGIES RELATED TO SPROCKET

Chain Pitch is the distance between the pin centerlines in a link of chain.


Pitch Diameter is the diameter of the theoretical circle that passes through the centers of the link pins when the chain is wrapped around the sprocket. This canʼt be measured on the sprocket itself, since it is a dimension used to design to tooth profile.


Bottom Diameter is the diameter of a circle tangent to the curve (called the seating curve) at the bottom of the tooth gaps. This dimension cannot be measured properly on odd-toothed sprockets, so the Caliper Diameter is used.


Caliper Diameter is the same as the bottom diameter for a sprocket with an even number of teeth. For a sprocket with an odd number of teeth, it is the distance from the bottom of one tooth gap to the bottom of the nearest opposite tooth gap.


Outside Diameter is the diameter over the tips of the sprocket teeth.


Hub Diameter is the outside diameter of the hub, which cannot exceed the chain clearance circle.


Maximum Hub Diameter is the largest size of hub, without interfering with the chain articulation (wrapping around the sprocket).


Maximum Bore is the largest bore that can be safely put into the sprocket. It must allow sufficient hub wall thickness for the applicationʼs torque, with allowances made for keyway and screws.

Articulation Angle/Angle of Flex is the angle by which the chain turns while entering or leaving a sprocket

Pressure Angle is the angle between a tangent to the tooth profile and a line perpendicular to the pitch surface.
