Test method for helicopter rotating part signal and wireless collecting device therefor

Abstract

The invention discloses a test method for a helicopter rotating part signal and a wireless collection device therefor. The method comprises: setting a sensing and collecting component on a rotating part of a helicopter, wherein the sensing and collecting component comprises one or more of the following ones: a strain gage and an optical fiber; obtaining the detection signal of the rotating component through the sensing and collecting component to detect the fault of the rotating component. According to the test method for the helicopter rotating part signal, the sensing and collecting component is arranged on the rotating part of the helicopter, and the detection signal is collected by setting a sensing component to detect the fault of the rotating component, so that online real-time monitoring on the signal of the helicopter on engineering application is achieved, basis is provided for troubleshooting the rotating component, the problems about overlong wire, tedious circuit and the like in the data collecting way of the rotating component are solved, and the problem that the helicopter rotating component in engineering application cannot be measured due to that good engineering application cannot be achieved in actual types is solved.

Description

technical field [0001] The invention relates to the field of measurement and testing, in particular to a method for testing signals of rotating parts of a helicopter and a wireless acquisition device. Background technique [0002] Helicopters play an important role in transportation, communication, rescue and modern warfare because of their vertical take-off and landing capabilities. As an important part of the helicopter, the rotating parts mostly have problems such as single channel and no backup. Once a failure occurs, it will cause serious accidents. [0003] The rotor system is the subsystem with the largest number of rotating parts in the helicopter subsystem, such as rotor blades, hub central parts, pitch change rods, etc. The rotor blade is the main provider of lift and maneuverability of the helicopter. If it cracks, breaks or even falls off, it will lead to a major flight accident; the central part of the helicopter hub is mainly responsible for fixing the main ro...
