The Road Load Simulator Facility located at the NASA Lewis Research Center in Cleveland, Ohio is described. This facility enables a propulsion system or any of its components to be evaluated under realistic vehicle inertia and road loads. The load is applied to the system under test according to the road load equation: F/sub net/ = K sub 1 F sub 1 + K sub 2 F sub 2 V + K sub 3 V exp 2 + K sub 4 (dv/dt) + K sub 5 sin theta. The coefficient of each term in the equation can be varied over a wide range with vehicle inertia representative of vehicles up to 7500 lb. simulated by means of flywheels. The required torque is applied by the flywheels, a hydroviscous absorber and clutch, and a drive motor integrated by a closed loop control system to produce a smooth, continuous load of up to 150 horsepower.
