Abstract

For the oblique launch of uncontrolled target projectile, a numerical simulation model of unsimultaneous derailment is established. With defined thrust conditions the influence of different launch angles and projectile weigh on the derailment velocity, time and angular velocity is analyzed. The motion interference of the projectile and launcher is checked. The rationality of the design of slider, projectile body and slide clearance is verified. And a ballistic correction scheme is proposed. Compare with the actual flight data of a target projectile. The result show that, motion characteristics of uncontrolled target projectile, when it leaves orbit, have a great influence on the subsequent flight trajectory. The correction scheme can effectively improve the accuracy of ballistic calculation.

Key words： uncontrolled target projectile; off slide; motion characteristics; flight trajectory
