对某飞行器对面攻击的飞行弹道特点和运动规律进行了分析,重点对影响全弹道最大的爬升段,进行了推阻、升阻和操稳等特性以及优化目标及约束条件的分析,通过对爬升律设计和推力调节规律设计两方面的优化,建立了理论模型。在以往的开环弹道设计方法之外,引入更为便利和准确的虚拟导引方法对爬升律进行建模,可以实现爬升段相对于爬升终点的闭环调节和分析,通过建立余气系数与高度/马赫数等相关因素之间的调度关系,得出了爬升段弹道的优化规律,并进行了弹道仿真对比分析,更好地满足了工程设计需求。
The characteristics of the flight trajectory and the movement rule of an aircraft opposite to the attack are analyzed. The most influential part of the whole trajectory is analyzed, and the characteristics of thrust resistance, lift resistance and stability are analyzed, and the optimization objectives and constraints are analyzed. Law design and regulation of thrust regulation in two aspects of optimization, the establishment of a theoretical model. In addition to the previous open-loop ballistic design methods, the introduction of a more convenient and accurate virtual guidance method to model the climbing law can achieve closed-loop regulation and analysis of the climbing section relative to the climbing end. By establishing the residual gas coefficient and height / Mach number and other related factors in the scheduling relationship between the trajectory obtained in the optimization of the trajectory and trajectory simulation comparative analysis to better meet the engineering design needs.
