The device can be used for measuring and calculating the angles simultaneously, and realizes the wireless transmission of measured data, remote measurement and control through being combined with the advantage of high dynamic response speed of the angular velocity gyroscope and the advantage of high multiplicity of the gravity accelerometer.

Description

technical field [0001] The invention relates to the angle measurement of an aircraft flight control system, in particular to a measuring instrument for measuring the rotation angles of a steering rod, a steering wheel, a rudder pedal and a rudder surface. Background technique [0002] When performing functional tests on the flight control system in the aircraft assembly workshop, it is necessary to measure the rotation angles of the steering column, steering wheel, rudder pedals and rudder surfaces. At present, the traditional two-axis gravity accelerometer inclination measuring instrument displayed by the traditional liquid crystal digital tube is usually used. This kind of measuring instrument has low measurement accuracy, and can only measure the rotation angle of the rotation axis parallel to the ground, and cannot measure parameters such as the rotation angle of the steering wheel, the rotation angle of the rudder surface, and other parameters that the rotation axis for...

AI Technical Summary

Problems solved by technology

This kind of measuring instrument has low measurement accuracy, and can only measure the rotation angle of the rotation axis parallel to the ground, and cannot measure parameters such as the rotation angle of the steering wheel, the rotation angle of the rudder surface, etc. The rotation axis has a certain angle with the ground

Moreover, when using this measuring instrument to measure, the work intensity of the test personnel is relatively high and the work efficiency is low. For example, in order to measure the angle of the rudder surface on the wing, the operator needs to stand on the wing for 2 to 3 hours, constantly Repeat the work of clearing and reading the measured value, and contact and report the data through the walkie-talkie

Therefore, the existing measuring instruments cannot meet the requirements of the flight control function test
