doi:10.3969/j.issn.1000-1093.2016.08.001

Abstract

Abstract: Based on the analysis of influence of plateau environment on rocket ballistics, a differential equations model is derived for the attitude motion of rockets. The law of attitude motion of rockets is analyzed. The law and causes of attitude motion of fin stabilized rocket on plateau are determined by analyzing the attitude test data on plain and plateau. The test results show that the attack angle of rocket increases rapidly after the end of the boost phase, and keeps at large angle for coning motion during firing at high altitude. In the case of low air density on plateau, the motion is caused by the effect of Magnus moment. A theoretical reference is provided for establishing the trajectory model, realizing the motion law of rocket and enhancing the firing precision of the weapons on plateau.

Key words: ordnance science and technology, plateau trajectory, rocket, attitude motion
