Abstract

The invention relates to the technical field of supersonic wind tunnel propeller power measurement test verification. The invention particularly relates to a supersonic wind tunnel propeller numericalmodel measurement and verification system and a control method thereof. A torque and rotating speed integrated sensor and a box type six-component balance are combined to measure performance parameters of a servo motor and a propeller, parameters such as propeller tension, lift force, torque, rotating speed (a servo motor and a propeller) and vibration are obtained in real time and sent into a real-time analysis system, a closed-loop design verification model of the torque, the bending moment of the balance, the rotating speed of the propeller and the rotating speed of the motor is formed, and the interference influence of errors generated by a single measurement system on a supersonic wind tunnel propeller test is avoided. A vibration sensor is used for monitoring and measuring the system state in real time, dangerous state points in the test process are avoided, the whole system is placed in a high-altitude environment simulation cabin, the whole structure is vertically installed onthe windward side of the center of a wind tunnel test section, and the system is applied to tests of propellers of different specifications in a supersonic wind tunnel in the high-altitude environment.

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, ...
