摘要
本文梳理了美国军方和军工部门提出的4个高超声速作战飞机概念方案,对比分析了各个概念方案的气动布局特点,按照时间线总结分析了两批概念方案气动布局的演化特征和方向。分析认为,美国高超声速作战飞机气动布局呈现出提升低速特性、降低内外流耦合程度、增加机身容量等演变方向,为紧密掌握高超声速飞机发展方向提供参考借鉴。
The paper reviews all 4 hypersonic military aircraft concepts released publicly by U.S.military departments and industries,contrasts aerodynamic configuration of those concepts,analyses the trends of aerodynamic configuration of U.S.hypersonic military aircraft.It concludes that the developing directions includes improving aerodynamic performance at low speed,reducing coupling degree between the internal and external flow,increasing the airframe volume,etc.,which could help to closely understand the evolution of hypersonic military aircraft.
