【Abstract】 This experiment is performed on a simple model of revolutionary body by means of gas injection on the wall.The results show that it is feasible to reduce the drag of submarine body by gas injection.Under given conditions,about 8% total drag reduction is obtained.Moreover,after an analysis of factors affecting the drag reduction authors point that it is possible to obtain more drag reduction in later experiments.更多还原
