Abstract:	In order to improve the design process of UAV assisted take off device, this paper proposes a parameter optimization method based on dynamic simulation. Firstly, based on the shape and structural parameters of the UAV, the Catia model of the assisted take off device is built and the mass and inertia information are extracted.Next, the aerodynamic shape parameters are calculated by Ansys CFD software, thereby obtaining the boundary conditions for the safe take off of the UAV.Then, the force of the take off device on the body and the impact of the collision between the body parts when the UAV takes off are simulated in Adams software. Meanwhile, the Matlab/Simulink module is applied to obtain the real time flight mechanics. Finally, the take off device is improved according to the obtained simulation results. In order to verify the rationality of the proposed scheme optimization design method, a simulation test of the assisted take off system under different working conditions is carried out considering the environmental factors with a certain type of solar powered drone. The structural parameters of the assisted take off device are improved through the simulation results.
