摘要
乘波构型作为一种能突破升阻比屏障的高超声速气动构型,是宽域可重复使用飞行器的一种重要候选气动布局形式。改善乘波飞行器低速性能不佳问题并实现宽速域飞行,已成为当前研究的热点。由于乘波飞行器采用了先设计流场后构造外形的思路,基准流场会影响其性能。本文对基准流场求解方法进行分析对比,并介绍了组合式、变马赫数和涡升力类宽速域乘波飞行器的设计方法,比较了各类方法的优势和不足,最后从基准流场和设计方法两个角度对宽速域乘波飞行器的未来发展提出了一些建议。
As a hypersonic aerodynamic configuration that can break through the lift-drag ratio barrier,waverider configuration is an important candidate for wide-speed reusable aircraft.Therefore.It has become a hot research topic that improving the low speed performance of the waverider vehicle and realizing wide-speed flight.Due to the idea of designing the flow field first and then constructing the shape of the waverider vehicle,the basic flow field will affect its performance.This paper analyzes and compares the calculation methods of the basic flow field,and then introduces the design methods of the combined,variable Mach number and vorticity lift wide-speed waverider vehicle,compares the advantages and disadvantages of each method.Finally,some suggestions for the future development of wide-speed waverider vehicle are put forward from two perspectives of basic flow field and design methods.
