摘要

以美国某WCMD为背景进行滑翔增程设计,以使其达到防区外打击的目的。文中借助商业CFD软件FLUENT获得了加装滑翔翼后WCMD在不同马赫数、不同攻角以及不同舵偏下的气动力系数和力矩系数;将计算所得的气动数据进行力矩配平处理后,进行了加装滑翔翼后WCMD的三自由度弹道仿真,结果表明文中所设计的滑翔翼能使WCMD达到防区外打击的目标,且对其它飞行器的滑翔增程设计有一定的参考价值。

Abstract

This article is based on a certain WCMD of America for hang-glider extended range (WCMD-ER) design, and then make the WCMD can carry out stand-off attack. Using commercial CFD software FLUENT acquire aerodynamic force coefficient and moment coefficient of this WCMD-ER on different Mach number, angle of attack and rudder bias; After processing aerodynamic data with moment balancing methods, then completing the three-degree of freedom trajectory simulation with this WCMD-ER, simulation result showed that the designed hang-glider make the WCMD attack stand-off, and the process of design have some benefit for other aircrafts' hang-glider extended range design.

Key words： WCMD; aerodynamic calculation; FLUENT; extending range; trajectory simulation
