Correlation analysis of starting state and peak current of autonomous starting turbine starter in plateau environment

The autonomous starting engine with airborne battery is an important means to ensure the rapid dispatch of the aircraft, and it is particularly difficult to start the aircraft in the plateau environment of low air pressure and low oxygen content. The peak current generated by the autonomous starting state can reflect the status of the gas turbine starter, effectively analyze the discharge performance of the airborne battery, and judge whether the autonomous starting is successful based on this, which has important research significance. In this paper, the equivalent circuit model of the autonomous starting engine with airborne battery is established, and the influence of the starting state of the turbine starter on the transient peak current of the autonomous starting is analyzed. Then the mechanism of judging the success or failure of turbine starter is obtained according to the peak transient current of the airborne battery. Finally, the actual loading test has carried out on the plateau to verify the validity of the theoretical analysis.
