Working in a team 4 four members a drag reduction system was designed for the Imperial Racing Green EV. The system works by tilting the two flaps on the wing, setting their angle of attack to 0 degrees. The project included -
1) There were 14 concepts which were considered, 8 concepts moved on to morphological analysis and detailed design was undertaken for 2.
2) Complete mechanical design of linkage mechanism which is housed within the endplates, with a total width of only 13mm

2) Complete mechanical design of linkage mechanism which is housed within the endplates, with a total width of only 13mm
3) Electronic design using an Arduino, which controls the opening and closing of the wing; the actuation happens in under 0.5 seconds which prevents the wing from stalling
4) Carbon fibre design, which included consideration for carbon layup, supporting foam and curing techniques
5) Water proofing methods and thermal dissipation were also key aspects of the design
6) A steady flow CFD analysis was conducted on SimScale to find the Drag and Lift forces, coefficients for the rear wing alone and the complete car in the high and low downforce configurations
7) A lap time simulation was conducted to estimate the performance benefit of using the DRS, there was a lap time reduction of 0.1 seconds over a 52 second lap. Vis mindre

This project was undertaken as coursework for the "Automotive Design and Motorsport Technology" module. The complete project included design of the electric drivetrain, battery module and braking system for the Imperial Racing Green EV; I was the brake team lead. The project included -
1) Study of the existing brake system on the ICE car and looking at possibilities for improvement. Two key areas were chosen for improvements, reduction in weight and making position adjustment easier.

1) Study of the existing brake system on the ICE car and looking at possibilities for improvement. Two key areas were chosen for improvements, reduction in weight and making position adjustment easier.
2) The first step in design was selecting the optimum angle for the master cylinders, stress analysis was conducted on the brake bar to find the optimum diameter such the it could withstand the pedal forces.
3) The brake arm was designed as an I-Beam since it results in a low maximum stress and reduces weight at the same time. Stress analysis was conducted to reach the ideal safety factor, hole placement on the cross section of the pedal arm was also considered.
4) Heat transfer analysis was conducted to design the disc brakes; this helped in selecting the correct type of disc brakes while reducing weight.
5) Brake Calliper selection followed next along with Master and Slave cylinder bias setup and a lockup check.
6) The base plate was designed such that it could be CNC milled out of one slab of aluminium, the mounting features for the pedals and springs were integrated into the base plate itself. The net weight of the base plate was only 886 grams. Stress analysis was conducted on the base plate to ensure it did not flex under applied load.
7) The final design was approximately 3.5Kg lighter than the previous version and shifting it to suit the height of the driver was made easier due to a simpler attachment design.

Researched was conducted on the existing and future advancements in EV technology. The study was focused on the asian market and covered the manufacturing of components, production of complete vehicles, limitations in terms of infrastructure, demand in the market and government schemes. Research showed that cost was a key limiting factor for developing economies such as India, infrastructure to support charing was another.

Researched was conducted on the existing and future advancements in EV technology. The study was focused on the asian market and covered the manufacturing of components, production of complete vehicles, limitations in terms of infrastructure, demand in the market and government schemes. Research showed that cost was a key limiting factor for developing economies such as India, infrastructure to support charing was another. The last step of the project was developing a business plan which encourages production and sale of EV's. The proposed plan changed the battery modules from being fixed to being replaceable; since batteries account for 40% of the net cost, buying a car without the battery module would reduce cost drastically. The battery modules would be available at charging station (similar to fuel pumps) where they would be stored, recharged and maintained under ideal conditions which would effectively increasing their life. EV drivers could have their modules replaced when they depleted the battery, and continue with their journey. Vis mindre
