The Research of Evaluation on Helicopter Power Supply System Based on Simulink

The performance of the power supply system is directly related to helicopter´s flight safety, therefore the evaluation on power supply system is very important in the design of helicopter. In this paper, the design evaluation techniques of helicopter power supply system are studied. Combined with the China´s national military standard GJB181A-2003, this paper evaluated and analyzed the three-level brush less alternator system as an example, introduced the digital signal processing techniques and performance parameters, then finally finished the assessment of the digital simulation model of the whole system under software Matlab/Simulink. The simulation results show that the proposed evaluation method has strong versatility and accuracy.
