Device and method for measuring deflection angle of aircraft rudder surface

Abstract

The invention discloses an airplane steering surface deflection angle measurement device comprising first and second connecting rods, and first, second and third angle measurement devices. The first ends of the first and second connecting rods are detachably and pivotally connected with an airplane rotating wing surface fixed side and an airplane steering surface respectively in use. The second ends of the first and second connecting rods are pivotally connected with each other and are away from the airplane rotating wing surface in use. The first, second and third angle measurement devices are respectively arranged at the first end of the first connecting rod, the first end of the second connecting rod and the second end of the first connecting rod so as to respectively detect the angles of a first inclined angle formed by the first connecting rod and the airplane rotating wing surface fixed side, a second inclined angle formed by the second connecting rod and the airplane steering surface and the first inclined angle formed by the first connecting rod and the second connecting rod. The invention also discloses an airplane steering surface deflection angle measurement method. The steering surface rotating angles of all angle wing potions within range from a horizontal steering surface to a vertical steering surface can be measured.

Description

technical field [0001] The invention belongs to the technical field of measuring devices, and in particular relates to a device and method for measuring an aircraft rudder surface angle. Background technique [0002] The aircraft rotating airfoil comprises a fixed side of the aircraft rotating airfoil and an aircraft control surface which can rotate around the fixed side of the aircraft rotating airfoil. In the actual flight process, the error between the actual flip angle of the rudder surface and the set angle directly affects the flight attitude of the aircraft. The motion attitude of the aircraft plays a vital role. In recent years, with the continuous development of aircraft for various purposes, the workload of rudder surface angle measurement is increasing, and the measurement accuracy requirements are getting higher and higher, so the demand for measurement technology of rudder surface rotation angle is also increasing. [0003] At present, there are three commonly...
