Abstract


Using ground-launched UAV is a booster rocket high degree of difficulty , numerous technical factors , but also a suitable ground-launched UAV technology, can greatly improve the efficiency of use of unmanned aerial vehicles and applications . In this paper, different booster mounting configurations based on the research , from the perspective of the overall design of the aircraft and discussed the separation characteristics of different configurations and choose the parallel configuration as well as a series of two typical configurations of UAVs ground-launched separate configurations were studied. Block structured grids using methods and nested grid , in considering the jet case, the use of CFD simulations booster at subsonic and supersonic speeds of 6DOF motion study the process of separation of the booster rockets and unmanned aerial vehicles aerodynamic characteristics , and the simulation calculation error and accuracy are analyzed. Based on simulation results and related research focuses on the effects of the booster rocket separated UAV flow field , has been separated from the booster rocket drones and aerodynamic characteristics . This paper studies done to help separate configuration choices UAV UAV surface heat protection design , separation time control law , the ground launch systems and separation systems research and design .
