The invention discloses a model tail boom device suitable for a fighter wind tunnel test. The model tail boom device comprises a motion mechanism, a follow-up mechanism, a base, a support rod and a motion controller, wherein the base is fixedly arranged above a wind tunnel closed test section, the motion mechanism and the follow-up mechanism are arranged on the base, and a test model is arranged at the tail end of the motion mechanism through using the support rod; the motion mechanism comprises a Y-direction motion assembly, a yaw angle motion assembly, a Z-direction motion assembly and a pitch angle motion assembly; and the follow-up mechanism comprises two follow-up assemblies which are located on the left side and the right side of the Y-direction movement assembly and are symmetricalin structure. According to the model tail boom device, motion control of the fighter aircraft test model in the yaw angle, the pitch angle, the Y direction and the Z direction is realized, the pitch angle and the yaw angle of the test model can be continuously changed in a large range, the center of the model can be guaranteed to be always located on the axis of the wind tunnel test section in thechanging process, the model tail boom device has small supporting blockage degree and small interference on a support of the model, and accurate and continuous aerodynamic data of a military fighterin a wind tunnel test can be effectively obtained.
本发明公开一种适用于战斗机风洞试验的模型尾撑装置,包括运动机构、随动机构、基座、支杆和运动控制器,基座安装固定在风洞闭口试验段的上方,运动机构和随动机构安装在基座上,试验模型通过支杆安装在运动机构末端;运动机构包括Y向运动组件、偏航角运动组件、Z向运动组件和俯仰角运动组件;随动机构包括位于Y向运动组件左右的结构对称的两个随动组件。本发明实现战斗机试验模型在偏航角、俯仰角、Y向和Z向上的运动控制,实现试验模型的俯仰角和偏航角可连续大范围变化,且能保证变化过程中模型中心始终位于风洞试验段的轴线上,本装置的支撑阻塞度小且对模型的支架干扰小,能够有效获得军用战斗机在风洞试验中准确且连续的气动数据。
