| Abstract: | A two-body system of plane-cargo's dynamics model is built based on the Lagrange analytical mechanics for a heavy equipment airdrop mission.A compensation scheme is proposed to weaken the cargo's impact to airplane.Numerical simulation shows the dynamic coupling between airplane and cargoes,and the relevancy between the size of extraction parachute and simulation results is analyzed.Numerical simulation results also supports the effectiveness of control law proposed in this paper,that is,flying qualities an... |
