The invention discloses an empennage supporting device applied to an airplane wind tunnel test, belongs to the technical field of airplane wind tunnel tests, and aims to solve the problems that the height of an airplane empennage is inconvenient to adjust, the test result is affected, and the test precision is low. The empennage supporting device comprises a bottom plate, and a plurality of universal wheels which are symmetrically distributed are fixed to the side wall of the bottom end of the bottom plate; a bearing plate is arranged over the bottom plate, a lifting assembly matched with the bearing plate is arranged on the side wall of the top end of the bottom plate, a pressing plate is arranged over the bearing plate, a positioning assembly matched with the pressing plate is arranged at the top end of the bearing plate, and an amplitude tester is fixed to the side wall of the top end of the pressing plate. Through the arrangement of the amplitude tester, the vibration frequency of the empennage of the airplane can be collected, after the amplitude frequency of the empennage is measured, a signal is transmitted to the controller and finally displayed through the amplitude tester, and the amplitude of the empennage of the airplane is accurately and effectively collected.
本发明公开了一种应用于飞机风洞试验的尾翼支撑装置,属于飞机风洞试验技术领域,针对了对飞机尾翼高度调节不便影响试验结果以及试验精准度低的问题,包括底板,底板底端侧壁固定有多个呈对称分布的万向轮,底板正上方设置有承载板,底板顶端侧壁设置有与承载板相适配的升降组件,承载板正上方设置有压板,承载板顶端设置有与压板相适配的定位组件,压板顶端侧壁固定有振幅测试器;本发明通过振幅测试器的设置,能够收集飞机尾翼震动的频率,测量出尾翼振幅频率后再将信号传递的控制器处,并最终通过振幅测试器显示,精准且有效的收集飞机尾翼振幅。
