The power system test device is a system that can verify the propeller design indexes. The system can collect propeller output power, propeller pull, propeller torque, and propeller speed in real time; the system includes a power test bench and an acquisition system.

The power system test device continuously drives the propeller to rotate at a certain speed through the motor and simultaneously measures the driving torque and the normal force of the propeller to provide effective test data for the design of propellers.
