Abstract
The paper introduces simulation model of a certain kind UAVs recovery procedure by using Matlab/Simulink software. The problem of time point to open main parachute (tm) in this UAV Recovery System is analyzed by simulation results of this model, and a series of meaningful conclusion is drawn. When recovery system works while UAV is flying steadily, tm becomes earlier as velocity increases, and later as pitch angle increases. tm is earliest when relieve drag parachute reefing at the time when control subsystem stops working. Larger the drag characteristics of the fully opened drag parachute is, earlier tm is, and larger the drag characteristics of the reefing opened drag parachute is, later tm is. These results are benefit for UAV recovery system design of this kind.
