Abstract

The invention discloses a measurement method and a measurement device for rotation angles of aircraft windshield wipers. The measurement device comprises two symmetrical fan-shaped dials and a supporting locating pin subassembly; a U-shaped opening is disposed in a central position of each of the fan-shaped dials; an angle marked line is disposed at a distal end of each of the fan-shaped dials; each of the fan-shaped dials is provided with a pointer; the U-shaped openings of the two sector-shaped dials are respectively clamped in rotating shaft protection walls of the aircraft windshield wipers; the two symmetrical fan-shaped dials are connected into a whole through the supporting locating pin subassembly; the pointers are respectively fixed on rotating shafts of the two windshield wipers,so that the front ends of the pointers respectively point to zero-degree marked line positions of the fan-shaped dials; the aircraft windshield wipers are started to drive the pointers to rotate so as to implement measurement for the rotation angles of the aircraft windshield wipers.

Description

technical field [0001] The invention belongs to the technical field of aircraft design and manufacture, and further relates to the detection and measurement of aircraft structures, in particular to a method and a measurement device for measuring the angle of rotation of an aircraft windshield wiper. Background technique [0002] The function of the windshield wiper of the aircraft is to provide a clear view for the pilot and co-pilot during the take-off roll, take-off, descent, and landing stages of the aircraft under rainy conditions to ensure flight safety. Whether the field of vision of the driver and the co-pilot is wide enough depends on whether the sweeping rotation angle of the windshield wiper meets the requirements. For example, there are two requirements for the rotation angle of the windshield wiper of the MA700 aircraft. One is that the retrace angle of the wiper when it is working meets 40°±2°; the other is that the angle of rotation of the wiper when it is park...
