Abstract:
The constitution, structure, working principle and launching process of the wedge-shaped pneumatic launcher of an unmanned aerial vehicle(UAV) are described.By simplifying its physical model, two dynamic models of the UAV launch system are established based on Lagrange equation and MSC.ADAMS, respectively. The curves of the acceleration and the velocity of UAV changing with time are obtained. The simulation results are compared with the experimental results to verify the correctness of the model. Then, the influence of the parameters on the launch is explored. Finally, the system is optimized. The maximum overload and the acceleration fluctuation are reduced.
