Testing

Phase 1 - Dimensionality

  • Must measure 11.75” diameter  x 1.25” wide

  • Rotor body must mount to a hub carrier  with eight 5/16” fasteners on a 7-inch bolt circle.

Phase 2 - Off-car testing

  • Reduce the static mass by 20%.

    • Was only able to acheive a 12% reduction in mass (12.9lbs vs 11.35lbs)

 

  • Confirm an existing manufacturer’s claim of 34% reduction in the moment of inertia. Litebrake.com

    • Material selection and careful machining was only able to reduce Moment of Inertia by 24%

Phase 3 - On-car testing

  • Rotor assembly must be able to resist the forces created by an angular velocity of 315 rad/sec (3000RPM)

    • AT 100MPH, rotor/wheel is spinning at ~1200RPM

 

 

  • Dissipate the heat generated from 125 kilowatts of kinetic energy if mounted on the front axle of the racing car

    • Repeatedly. For 74 laps until the rotor body warped.

 

 

  • Rotor must be able to resist the torque provided by the linear deceleration rate of 8 m/s^2

    • GPS Telemetry shows that entry/exit speeds and braking zone times are reasonaly consistent to provide proof of such a deceleration event
