Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention proposes an aircraft attitude adjustment method applied to ground thermal target calibration of airborne aircraft guns, which can effectively solve the problem that the structural strength of the contact surface between the jack and the aircraft cannot bear the load and the aircraft during the shooting process of the aircraft gun. The problem of aircraft slippage caused by aircraft recoil during the gun ground thermal target calibration process is especially suitable for the aircraft attitude adjustment of the airborne aircraft gun ground thermal target calibration where the aircraft gun is located above the back of the aircraft and the axis of the aircraft gun is raised relative to the axis of the aircraft.

Abstract

The invention relates to the technical field of aircraft calibration, in particular to an aircraft attitude adjustment method applied to ground thermal target calibration of airborne cannons. The support device is used to replace the front landing gear pillar to realize the cancellation of the nose jack, relying on the support device, left and right The height difference of the wing jack is used to realize the angle change between the aircraft axis and the ground horizontal line, to realize the downward tilt of the aircraft axis, and to make the height of the gun muzzle axis from the ground meet the requirements. The method can effectively solve the problem that the structural strength of the contact surface between the jack and the aircraft cannot bear the load during the shooting process of the aircraft gun and the problem that the aircraft slips due to the recoil force of the aircraft during the thermal target calibration process of the aircraft gun on the ground.

Description

technical field [0001] The invention relates to the technical field of aircraft calibration, in particular to an aircraft attitude adjustment method applied to ground thermal target calibration of an airborne aircraft gun. Background technique [0002] In order to check and adjust the dynamic characteristics of each aircraft's cannon system and the working characteristics of the cannon installation system and the bomb supply system for aircraft equipped with cannons, it is necessary to perform thermal target calibration of the cannons on the ground. One of the indispensable links in the ground thermal target calibration process of aircraft guns is the adjustment of the aircraft attitude. The height of the projection point from the ground. [0003] At present, the aircraft attitude adjustment method for aircraft gun ground thermal target calibration is to use 1 nose jack and 2 wing jacks to jack up the aircraft, and the 2 wing jacks are used to adjust the lateral level of th...
