Handheld aircraft borescope calibrator and calibration method

Abstract

The invention discloses a handheld aircraft borescope calibrator and a calibration method, and relates to the technical field of aircraft assembly and debugging. By using the specially designed and manufactured handheld borescope calibrator, the problem that a projection point is difficult to position in the borescope process of an aircraft is solved, and it is guaranteed that borescope personnel can rapidly and accurately determine the calibration position of the original point projection of a borescope on a target plate in the borescope process.. According to the technical scheme, the calibrator comprises a handle and a calibration disc. A cross curve is carved on the surface of the calibration disc, and the cross curve divides the surface of the calibration disc into four quadrants. The calibration disc adopts a hollowed-out design, and a hollowed-out point is located in the circle center of the calibration disc and is also the circle center of the cross curve of the calibrator. The hollowed-out point is a tapered hole. One end of the handle is fixed to the calibration disc, and the central axis of the handle coincides with the 30-degree radius line of one quadrant on the surface of the calibration disc.

Description

technical field [0001] The invention relates to the technical field of aircraft assembly and debugging, in particular to a hand-held aircraft target calibration device and a calibration method. Background technique [0002] Target calibration is an important method for checking the deviation of the photoelectric or mechanical axis of each airborne equipment relative to the reference axis during the aircraft assembly and debugging process, measuring the initial deviation and assisting deviation correction. The existing radar antenna, head-up display and other target calibration methods of a certain type of aircraft are to use the target calibration mirror to determine the origin of the reticle and project it onto the target board. Keep moving the marking pen until the final calibration. Due to the influence of on-site light, the influence of the background color of the target board, the interweaving of the target mirror and the grid lines of the target board, and the long-di...
