An electric aircraft propulsion test rig was designed and fabricated to predict thrust, torque, and battery discharge profiles for an electric aircraft. It included the DC brushless motor, carbon fiber propeller, charger, electronic controller, and lithium polymer batteries.

This apparatus allows for simultaneous measurement of the torque and thrust of the system through the use of a biaxial sensor. The test rig also measures system voltage and current, which allows the user to determine the discharge profile of the lithium polymer battery pack at various throttle settings.

The performance characteristics that are measured are system voltage, system current, temperature, motor torque, and propeller thrust. The system voltage and current data can be used to measure the Li-polymer battery discharge profile and develop the corresponding C rate. Also, torque and thrust measurements can be used for aircraft design purposes.
