The invention relates to the technical field of aerodynamic test devices, and provides an interstage free separation structure and a two-body free separation wind tunnel test device.The interstage free separation structure comprises a target aircraft model, and the target aircraft model comprises a front-stage model and a rear-stage model; the rear end face of the front-stage model abuts against the front end face of the rear-stage model, the front-stage model and the rear-stage model are attracted and fixed through a first electromagnet and a first electromagnetic armature, a power source and a controller are arranged in the target aircraft model, the power source is electrically connected with the electromagnets, and the controller is electrically connected with the power source; a force generating part is arranged between the rear end face of the front-stage model and the front end face of the rear-stage model and used for generating thrust to overcome magnetic force generated by residual magnetism of the first electromagnet. According to the method, the front-stage model and the rear-stage model can be freely separated, and the front-stage model and the rear-stage model can also be separated at a certain relative speed.
本发明涉及空气动力学试验装置技术领域,本发明提供了一种级间自由分离结构及两体自由分离风洞试验装置,级间自由分离结构包括目标飞行器模型,目标飞行器模型包括前级模型和后级模型,前级模型的后端面和后级模型的前端面相抵,且两者通过第一电磁铁和第一电磁衔铁吸附固定,目标飞行器模型的内部设有电源和控制器,电源与电磁铁电性连接,控制器与电源电性连接;前级模型的后端面和后级模型的前端面之间设有力发生部件,用以产生推力克服第一电磁铁剩磁产生的磁力。本发明既可使前级模型和后级模型之间能够自由分离,也可使前级模型和后级模型之间以一定相对速度分离。
