摘　　要：根据德国宇航中心设计的ATLLAS-M6运输机的气动布局特点,利用基于类型函数和形状函数的CST方法对其进行了参数化建模,并初步计算分析了该外形的主要气动特性,包括配平特性、静/动稳定性以及控制面的控制效率等。研究结果表明,类ATLLAS-M6的气动性能基本满足高超声速运输机的设计要求,其气动布局方案是可以借鉴的。在此基础上,将进一步考虑运输机结构重量、热防护性能等对布局的约束,对其外形进行多学科优化设计。The aerodynamic configuration study of ATLLAS-M6 transport aircraft proposed by the Ger- man Aerospace Center （DLR） is presented and discussed. The ATLLAS-M6 has a turbine-based combined cycle （TBCC） propulsion system, and it＇s aerodynamic configuration has the following characteristics： double delta-wing with low-aspect ratio, axial vertical tail, high-set horizontal tail and lifting body with high-fine- ness ratio. In this paper, a parameterized configuration is proposed via the ＂class function and shape function transformation technique＂ （CST） method. The aerodynamic characteristics are investigated, such as the trim characteristic, static/dynamic stability and control efficiency of control surfaces. The detail research indica- ted that the ATLLAS-M6 analog has a high hypersonic lift to drag ratio at the cruise state of low trimming angle of attack. The hypersonic stability derivatives predicted by the ＂dahlem-buck＂ method and the ＂prandtl-meyer＂ method shown that the transporter is static and dynamic stable in both lateral and directional directions and the proposed configuration is one of the feasible transporter choices. Yet, the aerodynamic configuration conceptual design of the hypersonic transport aircraft is a highly integrated project, several dis- ciplines involved must be considered farther, such as structured materials and thermal protection system. Therefore, the ＂multidisciplinary design optimization＂ （MDO） method would be used to optimize the ATI.- LAS-M6 analog aerodynamic configuration at the farther work.
