Design and implementation of detecting instrument for an airborne gun fire control computer

This paper proposes a detecting instrument for an airborne gun fire control computer. Shooting system is a typical opened loop control system, whose most important part is fire control computer. The state of fire control computer directly effects shooting precision of airborne gun, therefore it's necessary to detect faults in cycle. Based on analysing interface characteristic of fire control computer, the paper proposed a testing scheme of in-situ detection and ex-situ detection, introduced testing principle, designed hardware and software of the detecting instrument, analysed testing precision and data. After application in the army, it is proved that the detecting instrument has high precision and speed, supports training and combat effectively. The design idea and realizing technique is a useful reference for detecting navy gun servo system.
