A Fast Caculation Method for Shutoff Point of Rocket-Assisted Torpedo

为解决火箭助飞鱼雷射程与关机点计算速度问题,运用Chebyshev正交多项式拟合曲线,提出了一种基于时间或能量关机的计算方法。可根据不同的射程快速解算助飞雷关机点,达到实时控制助飞雷射程的目的,与现有方法相比,计算简洁、迅速。最后给出了关机方法软件的仿真流程,并将该软件应用于某助飞雷仿真系统,论证了该方法的可行性。

In order to settle the computing question between the range and the shutoff point of rocket-assisted torpedo, this paper applies curve fitting of Chebyshev polynomial to put forward a new calculating cut-off approach based on time and energy. This method can calculate the shutoff points quickly according to a variety of ranges, so as to control the ranges immediately. Comparing to other methods, this procedure has the characteristics of easily calculation and quick speed. Finally the feasibility of this approach is proven by an application to a flight simulation of one type of rocket-assisted torpedo according to the flow chart.
