velocity increment

Aiming at the obstinate after-working impulse and big thrust deviation of motor after depleted shutdown, a new hybrid orbit self-adaptive guidance scheme which combines velocity increment cutoff ( VIC) and terminal velocity matching correction was put forward.

针对固体火箭发动机在指令关机后存在量级小但顽固的后效冲量及推力偏差大等问题，提出了将速度增益制导（VIC）、末速匹配修正二者结合的混合轨道自适应制导方案。

The orbit injection parameters and firing attitude that affected velocity increment for orbital acquisition were presented. The relationships between the velocity increment and orbit semimajor axis, perigee altitude, inclination, and perigee argument were simulated.

给出了影响卫星定点捕获所需速度增量的入轨轨道参数和点火姿态等因素，并仿真计算了轨道半长轴、近地点高度、倾角和近地点幅角与速度增量的关系。
