为了让悬浮子弹能在空中达到一段滞空悬浮时间,设计了一种多管喷气旋转悬浮装置,并应用理论计算和试验验证相结合的方法对其进行研究。结合流体运动的基本方程及雷诺输运定理,建立了旋转喷气悬浮装置的进出气分析模型,并对试验样机进行了气动分析和试验研究。通过试验验证,得到了弯管长度、弯管曲率、喷管数量、喷管口部直径及质量流率对悬浮装置驱动性能的影响规律。

In order to keep suspension bullets staying in the air for a while, a multiple jet rotating suspension device was designed, and research combining theoretical calculations and experimental verification had been done on it. Combined with the basic equations of fluid motion and Reynolds transport theorem, inlet and outlet gas analysis model of the rotating jet suspension device and aerodynamic analysis and experimental research of test prototype had been done. The effects of the length, the curvature, the number of elbow pipe, the diameter of exit nozzle and flow rate on the suspension device driving performance were studied by validation experiments.
