The invention is suitable for the technical field of wind tunnel tests, and provides a vertical wind tunnel model pitching-rolling test device and a use method, and the test device comprises a base which is fixedly installed on a vertical wind tunnel test section tunnel wall platform; a stand column, the bottom end of the stand column being fixedly connected with the base; a supporting rod, located between the stand column and the web supporting bent rod, one end of the supporting rod being fixedly connected with the top end of the stand column, the other end of the supporting rod being connected with one end of the web supporting bent rod through a rotating assembly, and the rotating assembly being installed at the end, away from the stand column, of the supporting rod; and a belly supporting bend rod, the end, away from the rotating assembly, of the belly supporting bent rod being fixedly connected with the installation base, and the installation base being fixedly installed on the belly of the aircraft model. Free pitching/rolling motion of the airplane model under the action of aerodynamic force can be achieved, the structure is simple, mechanism rotation damping is small, interference is small, precision is high, and installation is easy, convenient and reliable.
本发明适用于风洞试验技术领域,提供了一种立式风洞模型俯仰‑翻滚试验装置及使用方法,其中所述试验装置包括:底座,所述底座固定安装于立式风洞试验段洞壁平台上;立柱,所述立柱的底端与底座固定连接;支撑杆,所述支撑杆位于所述立柱和腹撑弯杆之间,所述支撑杆一端与所述立柱的顶端固定连接,另一端通过转动组件与所述腹撑弯杆的一端连接,所述转动组件,安装于所述支撑杆远离所述立柱的一端;所述腹撑弯杆,在远离转动组件的一端与安装座固定连接,所述安装座固定安装于飞行器模型的腹部。通过本发能够实现飞机模型在空气动力的作用下的自由俯仰/翻滚运动,结构简单,机构转动阻尼小且干扰小、精度高,安装简便可靠。
