悬挂外挂物的气动相关性问题包括确定外挂物对飞机气动特性的影响;确定处于主机干扰流场中外挂物的气动特性;确定带外挂物飞机的颤振特性及确定外挂物安全投放条件等。本文试图通过歼×飞机2000多次风洞试验及其它试验和必要的计算分析对外挂物悬挂的气动相关性问题进行综合性研究和评述并给出一些结果,对一些研究方法进行了一般性讨论
The aerodynamic correlation of suspended objects includes determining the impact of external objects on the aerodynamic characteristics of the aircraft; determining the aerodynamic characteristics of the external objects in the disturbance flow field of the host computer; determining the flutter characteristics of the aircraft with the external attached object and determining the safe placement conditions of the external objects. This article attempts to carry out a comprehensive study and review on the aerodynamic correlation of the extermination object suspension by means of more than 2000 wind tunnel tests, other tests and the necessary computational analysis of J-X aircraft and gives some results, and gives a general discussion on some research methods
