The equipment comprises an azimuth and posture determining instrument and fighter vertical axis azimuth determining equipment, wherein the azimuth and posture determining instrument comprises an azimuth and posture regulator, a second fiber-optic gyroscope module is mounted on the azimuth and posture regulator, a computer for analyzing azimuth angle data is embedded into the second fiber-optic gyroscope module, an electronic optical aligner and a display are mounted on the second fiber-optic gyroscope module, both an integral solving module of the second fiber-optic gyroscope module and the display are connected with the computer through data transmission interfaces, the computer is connected with an integral solving module of a first fiber-optic gyroscope module through a data transmission interface, and the fighter vertical axis azimuth determining equipment can measure the current vertical axis direction of the fighter and indicate the direction through a cross line of sight, displayed in a level eyepiece. The method and the equipment have the advantages that steps in the process for calibrating fighter weapons can be effectively simplified, the calibrating efficiency can be effectively improved and the affect of natural factors can be prevented.

Description

technical field [0001] The invention relates to a weapon calibration method and equipment, in particular to a method and equipment for calibrating a fighter jet weapon system by using an optical fiber gyroscope. Background technique [0002] Weapon systems used on gunships and fixed-wing fighter aircraft require calibration before use, after weapons are changed, or when the pilot has doubts about their accuracy. The existing main calibration method is the reduced-distance target calibration method. Before target calibration, more than a dozen people must first coordinate the attitude of the top-level body, using the horizontal plane as a reference, and then use the wire-drawing method to determine the body position. During the entire weapon calibration process, the body position Both the measurement process and the target calibration process have the disadvantages of complex and cumbersome steps, low efficiency, and the need for a large number of people to work together, re...

The existing main calibration method is the reduced-distance target calibration method. Before target calibration, more than a dozen people must first coordinate the attitude of the top-level body, using the horizontal plane as a reference, and then use the wire-drawing method to determine the body position. During the entire weapon calibration process, the body position Both the measurement process and the target calibration process have the disadvantages of complex and cumbersome steps, low efficiency, and the need for a large number of people to work together, resulting in at least 3 to 4 hours for each calibration, which cannot meet the requirements of modern warfare for the rapid response of fighters. Easily affected by various natural factors such as terrain and wind, the accuracy of target calibration cannot be guaranteed, and it cannot meet the needs of target calibration at any time in the field environment
