摘要: 碟形飞行器是一种新颖的,采用翼身融合布局的飞行器.应用经典飞行动力学理论的线性化小扰动方法对碟形飞行器在低速条件下的纵向稳定特性进行了仿真计算,采用时域分析的方法对其纵向模态进行了分析,得到了碟形飞行器的纵向飞行品质状况,并进行了试飞验证.同时将碟形飞行器同常规布局飞机和飞翼飞机的特性做了简要的对比,分析了碟形飞行器同二者的异同之处和产生的原因.研究结果表明,碟形飞行器纵向模态稳定,具有良好的纵向飞行品质和综合性能.

Abstract: The saucer-shaped aircraft is a novel aircraft adopting blend-wing-body configuration. The linear perturbation theory based on the classic flight dynamics was used to analyze the longitudinal flight qualities of the saucer-shaped aircraft under low speed conditions, and the time-domain method was applied on the longitudinal mode. The longitudinal flight qualities were given by simulation. Meanwhile, flight tests were conducted to validate the analysis results. The aerodynamic characteristics of the saucer-shaped aircraft, the conventional aircraft and the flying wing aircraft were also contrasted to discuss their similarities and differences. The results show that he saucer-shaped aircraft has a stable longitudinal mode and exhibits superior flight qualities and excellent comprehensive performances.
