Design of the key systems in gas fluid pressure launch equipment of pilotless aircraft

The takeoff of pilotless aircraft launched by gas fluid pressure is an international advanced launch technology of pilotless aircraft.The gas fluid pressure launch equipment includes some key systems,such as gas fluid pressure power system,pulley accelerating system,sliding dolly system,unloading control system,buffer system for absorbing energy and so on.Some key systems are introduced and discussed detailedly from the point of view of design in this paper.The research resutt in the paper has been used for the development of certain pilotless aircraft system.And the new thought and method may come into being from it when designing other machinery with high-speed movement.
