The invention discloses an aircraft ground equivalent test turntable device, and belongs to the technical field of aircraft tests. Comprising a base, a supporting module, a pitch angle driving module and a yaw angle driving module, an aircraft scaling model mounting platform is arranged on the supporting module, and an aircraft scaling model is mounted on the base through the supporting module; the pitch angle driving module controls the support module to move, so that the included angle of the mounting platform relative to the horizontal plane is changed, and the pitch angle of the aircraft scaling model is adjusted; the supporting module is controlled to rotate relative to the base through the yaw angle driving module, so that the mounting platform rotates circumferentially in the horizontal plane, and then the yaw angle of the aircraft scaling model is adjusted. The rotary table continuously and controllably rotates under the high-speed blowing condition, and it can be guaranteed that the position of a nose in an airflow field is fixed while the posture of an aircraft model continuously changes in the blowing test process.
本发明一种飞行器地面等效试验转台装置,属于飞行器试验技术领域;包括底座、支撑模块、俯仰角驱动模块和偏航角驱动模块,所述支撑模块上设置有飞行器缩比模型安装平台,飞行器缩比模型通过所述支撑模块安装于底座上;通过所述俯仰角驱动模块控制支撑模块运动,使得安装平台相对于水平面的夹角产生变化,进而实现对飞行器缩比模型的俯仰角调整;通过所述偏航角驱动模块控制支撑模块相对底座转动,使得安装平台在水平面内进行周向转动,进而实现对飞行器缩比模型的偏航角调整。本发明在高速吹气条件下转台连续可控地转动,能够实现飞行器模型在吹气试验过程中姿态连续变化的同时,保证机头在气流场中位置固定不变。
