1102 Study on Dynamic Characteristics of High Speed Traction Drive CVT for Aircraft Generator

This paper shows the dynamic characteristics of traction drive integrated drive generator "T-IDG" and prediction method of them with showing the comparison between test results and simulation results. The simulation analysis of traction drive CVT has proved that the dynamic performance of T-IDG is affected not only by the geometric design and rotational speed as traditional theory but by the inertia, stiffness and other mechanical or hydraulic factors of T-IDG. The hydraulic control system of T-IDG based on this simulation analysis can help keeping the rotational speed of generator within MIL-STD-704 allowable limit against steep change of load.
