中文摘要:大型飞机研制过程中需要进行静态测力风洞试验,获得飞机小攻角条件下的气动特性,但对于飞机失速偏离尾旋研究,静态测力试验是不够的,无法获得飞机在失速过程中的动态特性与过渡过程。模型自由飞试验是一种动态试验,是通过飞机缩比模型来研究飞机的失速偏离尾旋问题,包括风洞模型自由飞试验和大气模型自由飞试验。
英文摘要:It is necessary to carry out the static force measurement wind tunnel experiments during the development of large civil aircraft in order to obtain the aerodynamic characteristics at low angle of attack condition. However, for aircraft stall/departure/spin research, static force measurement experiments are not enoughthe dynamic characteristics of aircraft stall is not obtained. Subscale model free-flight is a kind of dynamic experiment with aircraft subscale model to investigate aircraft stall/departure/spin problem, which includes wind tunnel free-flight test and atmosphere free-flight test.
