摘　　要：针对真实气体效应飞行试验的要求对试飞器气动布局开展了设计研究,采用平衡气体模型对真实气体效应进行数值模拟,通过与理想气体状态方程数值模拟结果的比较,分析了真实气体效应对不同试飞器外形气动特性的影响规律,总结出真实气体效应试飞器外形的基本设计要素,给出了适用于真实气体效应飞行试验的试飞器气动布局.Research on aerodynamic configuration design of demonstration vehicle was carried out, due to the requirement of real gas effect flight test in the present work. Equilibrium gas model was used to perform the numerical simulation of real gas effect. By comparing with numerical simulation result of ideal gas status equation, the influence of real gas effect on aerodynamic characteristic of different demonstration vehicle was analyzed and the basic design element of real gas effect demonstration vehicle was summarized. Last but not least, the aerodynamic configuration of demonstration vehicle that is applicable to real gas effect flight test was given.
