The invention relates to the technical field of simulation test systems, in particular to a hypergravity environment cross-medium aircraft hydrodynamic force reduced scale model test system, which comprises a cylinder body, a centrifugal machine is arranged in the cylinder body, and the centrifugal machine comprises a supporting structure, a driving mechanism and a rotating arm; a steering rotating shaft is arranged on the supporting structure, and the driving mechanism is arranged on the supporting structure; the rotating arm is arranged on the supporting structure and connected with the driving mechanism, one end of the rotating arm is provided with a counterweight hoisting hopper, and the other end of the rotating arm is provided with a hanging basket water tank; the wave maker is arranged in the hanging basket water tank; and the electromagnetic rail gun is arranged on the rotating arm. According to the test system, a conventional similar theory system is broken through and a new test principle is established in a super-gravity environment in a cross-medium scale test; the speed scale contradiction of structural mechanics and fluid mechanics is eliminated, the conflict of decompression cavitation number simulation and gas density coefficient simulation is solved, the value of the allowable minimum scale ratio beta0 is reduced, the dissolving amount of allowable gas in water is increased, and the model test can neglect the surface tension influence.

    本发明涉及模拟试验系统技术领域,具体涉及一种超重力环境跨介质飞行器水动力缩尺模型试验系统,包括:筒体,筒体内设有离心机,离心机包括支撑结构和驱动机构、以及转臂;支撑结构上设有转向转轴,驱动机构设于支撑结构上;转臂设于支撑结构上,且与驱动机构连接,转臂的一端设有配重吊斗,转臂的另一端设有吊篮水箱;造波机,设于吊篮水箱内;电磁轨道炮,设于转臂上。该试验系统跨介质缩尺试验在超重力环境下,突破常规相似理论体系,建立新试验原理,消除了结构力学和流体力学速度缩尺矛盾、解决了减压空泡数模拟与气体密度系数模拟冲突、减小了允许最小缩尺比β0的值、增大了允许气体在水中的溶解量,并使模型试验可以忽略表面张力影响。
