Abstract:

Accurate-point recovery of unmanned aerial vehicle (UAV) is a critical technology to promote the widespread use of small- and medium-sized UAVs. The rope-hook recovery technology provides an advanced accurate-point recovery method for small-sized fixed-wing UAV in limited recovery fields or naval vessels, which is of great value in advanced research and application and has splendid future. The space mechanism dynamics problem of the rope-hook recovery system is resolved by using the simultaneous constraint method based on the closing-vector-circle method and Euler kinematical and dynamical equations. The energy-absorbing and buffer capability of the rope-hook recovery system is deeply analyzed based on the dynamic modeling of UAV rope-hook recovery system. The main characteristic of the system, for instance, the velocity change, is estimated through the simulation of the dynamics modeling in the environment of MATLAB/Simulink. The influences of parameter variation on the system's main characteristics are discussed. The stress and strain of the wing forced by the arresting peak load in the process of recovery are analyzed. The results and analysis show preliminarily that the rope-hook recovery system has good performance and is a new recovery technology to develop. It offers a significant theoretical reference for the manufacture of the UAV rope-hook recovery system.
