Abstract

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.

Key words： jet rotation; aerodynamic analysis; experimental research; drive performance
