  1. Instructor: Raresh Pascali Underclassman: Matt Walsh Team Members: Daulet Urkenbayev (Project Manager) Paul Orieukwu(Frame Designer) Jonathon Fulbright (Electrical System Designer) Rajeev Bhattacharya (Mechanical System Designer) :

  2. Competition Objective • To challenge teams of university students to conceive, design, fabricate, develop, and compete with small, formula-style hybrid-powered cars. • The formula hybrid competition is intended as an educational program requiring students to work across disciplinary boundaries. • To allow teams to freely express design, engineering, and imagination. • Teams are allowed eight to twelve month to design, build, and test for the competition.

  3. Competition Scoring • Top three teams that score the highest points will receive trophies and awards.

  4. Team Goal • Register for competition before slots fill. • Successfully implement switchable hybrid drive. • Finished curb weight not to accede 650 pounds. • Successfully implement data logging system. • Complete unrestricted 75 meter (246 feet) acceleration run in 5.4 seconds or less. • Complete the final assembly by April 1.

  5. What is a Hybrid? Parallel Hybrid System Layout Energy flows in 2 parallel paths from reservoirs to the wheels. Series Hybrid System Layout Energy flows in one path from reservoir, through all components, and finally to the wheels.

  6. Design Outlook Both Parallel and Series configuration have different advantages and disadvantages. This is why we plan to implement a design that has the ability to switch between the two. In theory, this should achieve the best of both worlds.

  7. Material Market Research Carbon Fiber Yield Strength = 710684psi Modulus of elasticity = 33000ksi Material Consideration • Weight • Feasibility • Strength • Cost Aluminum Yield Strength = 31000psi Modulus of elasticity = 10000ksi Steel Yield Strength = 50800psi Modulus of elasticity = 29700ksi

  8. Conceptual Frame Design • Must meet the 95th percentile male and 5th percentile female template. Lawrence Technology University SAE Frame University of Idaho SAE Frame University of Houston SAE Frame

  9. Aerodynamic Devices • Back Wing • Front Wing • Diffuser • All of these device are used to increase the downforce on the vehicle by manipulating the air flow.

  10. Conceptual Design of Body • These are the top three teams who scored the highest in the design category. • Expectation for our project is for it to be unique and marketable. • (1) McMaster University • (2) University of Idaho (3) Embry-Riddle Aeronautical University
