摘要
为了提升高超声速飞行器在低速和超声速条件下的气动特性,提出了一种新型宽速域类乘波体机身加可变菱形连接翼的气动构型,飞行器通过连接翼的收放变化来实现展弦比和掠角的增减,提高全速域范围的气动性能。采用CFD方法,对低(超声)速和高超声速时的气动特性进行了数值计算。通过分析计算得出结论:在低速和高超声速时,飞行器的气动特性良好。结果表明,该设计方法是可行的,符合水平起降、宽速域飞行的发展趋势。
In order to improve aerodynamic characteristics of a hypersonic vehicle at low and supersonic speed, a novel aerodynamic configuration is put forward for wide-speed range Mach number, which is combined by quasi-waverider and variable diamond shaped joined-wing. The aerodynamic performance of the vehicle is improved by contraction and release of the joined-wing for wide-speed range. In this paper, the CFD was used to investigate its aerodynamic characteristics at low speed,supersonic speed and hypersonic speed. By analyzing the result,it is concluded that the aerodynamic characteristics of aircraft is good at low speed and hypersonic speed. The result shows that this design method is feasible and conforms to the development trend of horizontal take-off and landing and wide speed range flight.
