And the effect of the work order of the two propellant units to the performance of the trajectory and the matching conditions to obtain the theoretical optimum trajectory is discussed too. according to the ballistic speciality of a hybrid base - bleed - rocket extended - range projectile during base - bleed and rocket work, its physical parameter is non - constant, such as its mass position of mass centre polar and equatorial moment of inertia. after a mulriple ballistic model of constant physical parameter is established, a mulriple ballistic model of continuous and non - continuous physical parameter is educed and the program is compiled, the theoretical tool is constructed to study othe other pivotal technology of a hybrid base - bleed - rocket extended - range projectile
本文根據底排?火箭復合增程彈其底排燃減阻和火箭助推階段的質量、質心位置、轉動慣量等結構特徵參量變化的彈道特徵，在建立底排?火箭復合增程彈結構特徵參量為不變常量的多元彈道計算模型基礎上，導出了結構特徵參量為連續變化量和非連續變化量的底排?火箭復合增程彈多元彈道計算模型，編制了相應的計算機數值分析程序，構建了研究底排?火箭復合增程彈其它關鍵技術的理論工具。
