Digital aerogun target-correcting method applied to airplane general assembly

Abstract

The invention discloses a digital aerogun target-correcting method applied to airplane general assembly. The method comprises the following steps of: 1) leveling an airplane and unifying a measuring coordinate system of a laser tracking instrument with an assembling coordinate system of an airplane general assembly station; 2) measuring 2# and 12# points by using the laser tracking instrument andautomatically building a symmetrical axis of the airplane by using a computer; 3) starting a measuring program and measuring four target points on an aerogun target-correcting tool in a manually or automatically measuring mode; 4) calculating and graphically displaying a distance between a midpoint of a connecting line of left and right gun barrel aiming points and a central point of a target plate, if the distance meets the requirement, finishing the aerogun target-correcting process, and if the distance does not meet the requirement, turning to a step 5); and 5) according to the prompt of acomputer, manually regulating the aerogun and repeating the steps 3) and 4) after regulating until the distance meets the aerogun target-correcting requirement. The method has the advantages of effectively improving target-correcting precision, greatly improving target-correcting efficiency, obviously reducing the dependence of the target-correcting operation on the work on-site space size and improving the automation and integration levels of the airplane general assembly.

Description

Technical field [0001] The invention relates to a target calibration method, in particular to an aerial gun digital calibration method applied to aircraft assembly. Background technique [0002] Air cannon is a kind of non-control weapon equipped on most modern combat aircraft. It is mainly used to attack short-distance visible targets. It can shoot enemy aircraft in the air and attack ground targets. The purpose of the aircraft cannon calibration during the aircraft assembly process is to install the cannon to maintain a certain position with the aircraft fuselage axis and related accessories, such as the coordination of the mutual position of rockets, missiles and sights. Over the years, my country’s aerial artillery target calibration method still follows the traditional optical school target method, with low automation, poor reliability of measurement data, and large work site space, which seriously inhibits the improvement of calibration accuracy and calibration. Efficiency ...
