探讨了战斗机内埋式武器舱的一些研究进展,对武器舱形状、来流马赫数、边界层厚度、噪声等对武器安全投放的影响进行综合分析,重点讨论了武器舱几何形状对流动特性的影响;基于N-S方程,采用数值模拟方法,分析了几种不同长深比二维武器舱的流动特性,以及三维武器舱锯齿舱门对气动特性的影响;探讨了噪声特性及噪声抑制技术,并对武器投放中涉及的隐身性能进行了分析讨论。
This paper discusses some research progress of the fighter aircraft cabin with embedded weapons, and analyzes the influence of weapon cabin shape, Mach number, boundary layer thickness and noise on the safe deployment of weapons. It focuses on the influence of the geometry of the weapon cabin on the flow characteristics Based on the NS equation, the numerical simulation method is used to analyze the flow characteristics of several different deep-to-deep two-dimensional weapons compartments and the influence of three-dimensional weapon cabin serrated hatch on the aerodynamic characteristics. The noise characteristics and noise suppression techniques are also discussed The stealth performance involved in the delivery of weapons was analyzed and discussed.
