In order to meet the development requirement of the arresting net recovery system for certain unmanned aerial vehicle (UAV),the dynamic models of arresting process are built and simulated.The results of numerical analysis indicate that the mass and the shoving net speed of the UAV, and the rotor radius of the turbine damper are the key parameters affecting arresting process.The UAV with different mass can be recovered safely in mutative arresting distance by adjusting the design parameter.The simulation results are well in accordance with the experiment results,so that the dynamic models of arresting process is validated by the comparative study between simulation and experiment.
