Design of Efficient Power Generation System for Composite Wing Unmanned Aerial Vehicle
To enhance the maneuverability and expand the reconnaissance range of composite wing unmanned aerial vehicles,a design scheme for a 6 kW power generation system of a 50 kg class composite wing unmanned aerial vehicle is proposed.Selected electrical system topology structure to achieve integrated motor starting and starting.Using motor electromagnetic theory to calculate and determine the armature design parameters of permanent magnet synchronous generators.Study the performance characteristics of the engine,combine electromagnetic field calculation models and finite element simulation to determine the winding form,and match the rated electrical power output of the generator with the peak operating speed of the engine.The prototype generator has been tested on a ground test bench and can achieve integrated starting and power generation,and can continuously output rated power of over 6 kW.The power generation system has established an efficient energy flow relationship for composite wing unmanned aerial vehicles,with an energy density higher than that of lithium polymer batteries by 15.4%,and has a good electromechanical matching effect.
