THE TEST TECHNICAL RESEARCH OF SHOOTING PRECISION ON ANTI-AIRCRAFT MACHINE GUN

摘要

Owing to the lack of sound test establishments and feasible testing and measuring technologies, the execution of present anti-aircraft machine gun precision tests have to rely on the balloon-hung targets method or closely fixed hanging targets method, which are not only complicated and wasteful with a bad precision result, but also can only be treated as a qualitative exam rather than a quantitative evaluation. Based on the analysis of the factors affecting the bullets dispersion of the anti-aircraft machine gun, and the precise measurement of the major parameters affecting the dispersion precision through advanced measuring technologies, this paper set up and choose a suitable ballistic calculation model to conduct precise ballistic simulation calculation. This kind of calculation helps to ascertain the dispersion of the bullets in a random area inside the test area. Then after the validation of tests, we make a scientific project to conduct the anti-aircraft machine gun precision test, and by this way, we lay the theoretical foundation and provide concrete execution method for the anti-aircraft machine gun precision test in the future.
