Pulse Trajectory Correction Correction Method

In modern battlefield the intelligent munition is not only decides the victory of the war but also come down to decrease of non-battle object. The trajectory correction projectile is the typical delegate. One of the technical difficulties is how to choose the correction implement mechanism with high performance and low cost.The small solid rocket impulse engines have the advantages of small volume, short reaction time, and simple configuration, low cost, so it is a right choice.To satisfy the requirements of developing ground-to-air trajectory correction, based on external ballistics and the characteristic of impulse engines, found one corrected model .Backing ground on 57mm shell of antiaircraft gun ,analyses the stability when the impulse working, drew the picture about the attack angle and got the stable area. The results have an important meaning.Gaining the rules between correction distance and the impulse power, correction angle, correction time, the numbers of impulse engine, duration of one impulse. The result of emulation about accelerating and turning maneuver shows that the distance between target and shell was decreased evidently,. The result proved that the model is correct. So the TCM which are corrected by impulse engines have a actual meaning.
