Abstract针对乘波体在高空以高马赫数飞行时的特点,给出了一种考虑高温平衡气体效应的乘波体设计方法,并通过数值模拟的方法研究了高空高马赫数飞行条件下高温平衡气体对乘波体气动特性的影响。研究结果表明,相对于完全气体,平衡气体对乘波体的气动力特性影响不大,但对乘波体的前缘驻点区和下表面的热流及辐射平衡温度有较大的影响。另外在乘波体较为适宜的飞行攻角范围内,攻角的增大不会显著改变平衡气体效应对乘波体气动力特性的影响,也不会显著改变平衡气体效应对乘波体前缘驻点区的热流与辐射平衡温度的影响,但却会在一定程度上减小平衡气体效应对乘波体下表面的气动热及辐射平衡温度的影响区域。
Other AbstractA method including equilibrium gas effects have been given to generate waveriders fling at high altitude with high Mach number.And the CFD technique has been used to investigate the equilibrium gas effects on aerodynamic and aerothermal characteristics of waveriders fling at high altitude with high Mach number.The results indicated that the equilibrium gas affects aerodynamic characteristics of waveriders slightly in comparison with perfect gas,but it does have some effects on the aerothermal characteristics of the nose region and lower wall for wavriders.Additionally,the angle of attack,which is suitable for waverider,will not change the equilibrium gas effects on aerodynamic of waveriders and heat flux and radiative equilibrium temperature of nose region of waveriders,but it will narrow the region affected by equilibrium gas of heat flux and radiative equilibrium temperature down for lower wall of waveriders.
