The present invention relates to the technical field of supersonic wind tunnel propeller power measurement test verification, in particular to a supersonic wind tunnel propeller numerical model measurement and verification system and its control method, combined with a torque speed sensor and a box-type six-component balance to measure servo motors and propeller performance parameters , real-time acquisition of parameters such as propeller pull, lift, torque, speed (servo motor, propeller), vibration, etc., and sent to the real-time analysis system to form a closed-loop design verification model of torque and balance bending moment, propeller speed and motor speed, avoiding a single The error generated by the measurement system interferes with the supersonic wind tunnel propeller test; and the vibration sensor is used to monitor the state of the measurement system in real time to avoid dangerous state points during the test. The entire system is placed in a high-altitude environment simulation cabin, and the overall structure should be installed vertically Located on the windward side of the center of the wind tunnel test section, it is applied to propeller tests of different specifications in supersonic wind tunnels in high-altitude environments.
Description
technical field [0001] The invention relates to the technical field of supersonic wind tunnel propeller dynamic measurement test verification, in particular to a supersonic wind tunnel propeller numerical model measurement verification system and a control method thereof. Background technique [0002] At present, there is no supporting equipment for power acquisition in the high-altitude environment, and it is impossible to obtain performance parameters such as propeller pull, lift, torque, rotational speed (servo motor, propeller), and vibration for real-time evaluation of propellers of different specifications in the high-altitude environment. Therefore, it is urgent to provide a simulation The device can be placed on the ground to simulate the high-altitude environment and simulate the propeller power of the aircraft. [0003] However, only a small number of analog dynamic measurement systems that have appeared so far have complex structures and high manufacturing costs, ...
