Combined type propeller thrust torque measurement device

Abstract

The invention provides a combined type propeller thrust torque measurement device and belongs to the technical field of force measurement. The device comprises a motor, a propeller and a sensor balance. The sensor balance comprises a vertically-pulling pressure measuring mechanism and a horizontally-pulling pressure measuring mechanism. An output shaft of the motor penetrates through a push-pull force bearing pedestal to be connected with the propeller. The vertically-pulling pressure measuring mechanism is arranged below the motor, and the horizontally-pulling pressure measuring mechanism is arranged below the vertically-pulling pressure measuring mechanism. The vertically-pulling pressure measuring mechanism comprises a detachable vertically-pulling pressure sensor, and the horizontally-pulling pressure measuring mechanism comprises a detachable horizontally-pulling pressure sensor. The combined type propeller thrust torque measurement device is simple in structure, and convenient to disassemble and assemble; even if pulling pressure sensor components are damaged by accident impact and violent vibration in the on-board testing process, the pulling pressure sensor components can be replaced at any time, and the combined type propeller thrust torque measurement device can be continued to be used.

Description

technical field [0001] The invention relates to the technical field of force measurement, in particular to a combined propeller thrust torque measurement device. Background technique [0002] The air propeller is a tool that converts the power of the aeroengine into the propulsion of the aircraft. In the process of aircraft research and design, the thrust and torque data of the propeller are important input conditions for the identification of its aerodynamic parameters. Generally, the flight is simulated through a wind tunnel test or a vehicle test. Working conditions, measure the aerodynamic performance data of the propeller, and provide a basis for research and design work. [0003] When performing propeller dynamic characteristic test experiments, the existing measuring devices generally use balance mechanisms. However, during the vehicle test or real flight test, the propeller, motor and other components of the propulsion system will generate large vibrations or be sub...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a combined propeller thrust torque measurement device, which aims to improve the existing propeller thrust torque measurement device. During the vehicle test or real flight test, because the components of the propulsion system are prone to large vibrations or unexpected instantaneous shocks As a result, the measurement accuracy is low, and the tension and pressure sensor parts are easily damaged, and it is difficult to replace after damage, resulting in the problem that the balance mechanism can no longer be used.
