无人机电磁弹射器的综合制动方法
Hybrid brake method for electromagnetic launcher of unmanned aerial vehicle
摘要
Abstract
Electromagnetic launcher for unmanned aerial vehicle (UAV)which utilizes linear motor to accelerate in short distance is already a new trend for launching fixed-wing UAV.To brake shuttle in shorter distance when aircraft taking off,a hybrid brake method including solid stator eddy current brake,eddy current brake based on Halbach permanent arrays and rubber damping brake was proposed and analyzed.When the speed of shuttle is above 10 m /s,it is notable for the brake by means of solid stator eddy current brake.In addition,when the speed of shuttle is below 3 m /s,the brake force induced by solid stator eddy current is decreased greatly.It can increase 30% brake force by Halbach permanent arrays eddy current brake.By model analysis and collision experiments,rubber damping brake can absorb kinetic energy to brake shuttle in short distance as the final stage brake.关键词
