Dynamics Analysis for the First Fire Running away from the Fire Gang of the Antiaircraft Machine Gun

摘要

When examining the precision of the antiaircraft machine gun's running fires, people often meet the problem that the first fire runs away from the gang. There are obviously departure between the first fire and the others. It makes the precision between the single fire and the running fires contradictorily. And it can't be solved by fire's emendation. It makes the firer attended to one thing and lost another and takes great effect in the precise-fire demand which need first fire hitting the target and first group overcastting the targets. In this paper, we will discuss the direct reason of problem that the first fire runs away from the gang. It is that gunpoint flounce leads to big reverberation difference angle of the next fire. And we will also make the dynamics analysis of gunpoint flounce in force and frequency response function and other characteristics. At last, we will put up some measures on how to cut down on gunpoint flounce.
