摘要
在研究了翼型叶片腹支（前、后位）／尾支对大展弦比飞机全机及部件的纵向干扰特性，尾支对全机横向干扰特性，并分析了各种支撑对飞机各部件干扰的影响之后表明：对于不同平尾位置的大飞机，前位叶片腹支是三种支撑中干扰最小的，其纵向干扰量均小于风洞试验最大误差。利用前位腹支－尾支组合进行大飞机纵、横向试验具有明显的优越性。
An investigation has been conducted to determine the longitudinal aerodynamical interference effects of support system of airfoil section ventral strut(forward/aft)and sting on complete aircraft model with large aspect ratio and its components,and the lateral aerodynamical interference effects of sting on that complete aircraft model.The interference effects of various supports on components of the aircraft have been analysed. The support interference of the forward ventval strut is the lowest in the three kinds of supports for large aspect ratio aircraft with different tail positions,and the longitudinal support interference is less than the maximum error of wind tunnel test.Using the combined support system of forward ventral strut and sting to conduct the longitudinal and lateral tests of the large aspect ratio aircraft is of superiority.
