The Hanging Scheme and Simulation Analysis for the Tail Cabin of Launch Vehicle based on Aerial Recovery
The hanging process is one of the key links in the Mid-Air retrieval of launch vehicle.According to the whole process of the launch vehicle tail cabin hanging in the air,the design of the hanging device based on the helicopter as the recovery platform is carried out.The hanging device includes tension sensor,load shedding device,overload protection device and the actuator in the end of the hanging device.Parafoil and parachute eject from the bottom of the tail cabin of launch vehicle.The hanging device can realize the hanging operation of the retrieval by hanging attached apex drogue on the top of parafoil.Through the simulation analysis of the hanging process,it can be seen that when the weight of the retrieval increases,the overload increases significantly.When the parachute retraction time increases,the load reduction effect is obvious.
