低成本中高空超音速靶标弹道优化设计

Trajectory Optimization of Low-cost Supersonic Target at High Altitude

为了寻求一种价格低廉的中高空超音速靶标,文中拟定了战技指标,通过分析最终采用大口径超音速火箭弹改装,建立了以主动段末端速度及弹道倾角为设计变量,以供靶段水平距离为目标函数,满足战技指标的优化模型,再将优化结果反推得到主动段参量。经仿真证明该方法合理可行,可用于指导试验,能大幅度降低试验成本。

For seeking an inexpensive supersonic target at high altitude,tactical and technical data was studied. A big-caliber supersonic rocket was adopted for refitting finally. A mathematical model meeting tactic-technical specifications was established. In this model, burnout velocity and burnout trajectory tilt angle were set as the design variables, and effective target horizontal distance was set at the target function, powered phase parameter could be inferred subsequently. After simulation, the method was proved to be feasible, can reduce experimental cost greatly.
