运载火箭减载控制技术研究

Study on Load Control Technology of Launch Vehicle

分析了被动减载和主动减载的机理,给出了基于减载的火箭攻角、摆角计算方法,并进行了相应的数值仿真。理论分析和仿真结果表明,采用被动和主动减载能够有效地减小火箭飞行攻角和发动机摆角,进而降低箭体载荷。同时,给出了一种攻角反演算法,以分析减载效果。

The mechanisms of active and passive load control were analyzed,the calculation methods about angle of attack and engine swing angle were given,and numerical simulation was considered.Theory analysis and simulations show that the methods of the active and passive load control could decrease angle of attack and engine swing angle,and decrease load of missile further.In order to analyze load control effects,a inversion arithmetic was proposed.
