Performance Simulation of Small UAV Ejection Frame Based on Simulink

The ejection system dynamic model was established for the catapult launch analysis and design simulation plat.form to improve high credibility. The UAV catapult dynamics and kinematics model was established, by which the catapultlaunching system was researched in this paper. Based on the Matlab/Simulink module, the analyses were conducted on theelastic coefficient, elastic element guide rail length, the plane launch speed parameters. In the process of simulation, bychanging different parameters of system, the influence law of these parameters on the ejection system performance was ob.tained. Reasonable matching these parameters, eject a variety of models of UAV could use this system, improve the effi.ciency, save the test resources and funds. At the same time it provided theory for UAV ejection system research and devel.opment.
