摘要
Abstract
In this paper, the MSC.Dytran finite element analysis software was used to simulate the fuel response in the process of the UAV rocket assisted takeoff. The ALE method was used to simulate the interaction between the fuel and the fuel tank. The change of UAV take-off attitude and the sloshing of fuel in the fuel tank were obtained by simulation under conditions of different amount of fuel in the fuel tank, the results showed that the change of UAV take-off attitude with half fuel was the most serious. In order to reduce the fuel sloshing, several improved designs of instaling spacer in the tank were studied. And the improvement effects were calculated. Based on the simulation results, some suggestions were given for the layout design of the tank. The method in this paper is expected to be used for the accurate simulation of UAV Take off phase.关键词
