DESIGN CHARACTERISTIC AND METHOD OF THE FLYWHEEL MOTOR OF CIHFAPE USED IN HELICOPTER

摘要

The flywheel motor is one of the best ways to improve the power-to-weight ratio of heavy fuel helicopter that equipped with compression ignition heavy fuel aircraft piston engine (CIHFAPE). In this paper, a flywheel system is designed, engine start, power demand of helicopter and rotation landing with flywheel motor are studied. Design characteristic of flywheel motor is studied for the application background of the helicopter designed by us, and the design indexes are given. The design method of the flywheel motor is proposed based on this Design characteristic, and the design is given. Finally, the performance of the flywheel motor designed by this method is verified by finite element method (FEM).
