【Abstract】 Air bag forms an effectively protective cushion in the recovery of UAVs (unmanned aircraft vehicles)and has been successfully used in many types of UAVs abroad.In this paper,we improved on the design of a recovery air bag using optimum method.A model for optimal calculation of the cushioning characteristis of the bag was established.The calculation was based on the results of a preliminary air bag drop test.The expected objectives were reached only through several drop tests.The method was proved to be effective.From its successful application,it is proved that this method is a practical way of recovery air bag design.更多还原
