The dynamic model of LAPES base on separate method

摘要

LAPES (Low Altitude Parachute Extraction System) is one of the three methods used for Aerial Delivery. It can transport the cargos, weapons and equipments to the front fast. However, it also makes a high demand to the aircraft. The drop sequence's low altitude allows for no margin for pilot error and a plane crash is real dangerous. This paper takes the cargos which are moving in the aircraft or falling off the aircraft as the disturbance to build dynamic model of the plane. Then, try to obtain the posture response of the aircraft when engage in the airdrop through the simulation. The result will be helpful to provide a foundation to design the control system of the airdrop to ensure the safety of the plane.
