APU AIRCRAFT AUXILIARY POWER UNIT APU CONTROL SYSTEM HAVING SPEED COMPENSATION

摘要

An auxiliary power unit (APU) control system for an aircraft is disclosed. The APU control system includes an APU, one or more processors, and memory coupled to the one or more processors. Memory includes data including database and program code that, when executed by one or more processors, cause the APU control system to receive one or more ambient signals representing air density values and one or more power signals representing a specific amount of power generated by the APU. To save. The APU control system further determines the variable rotation speed of the APU based on the air density value and commands the APU to operate at the variable rotation speed. When operating at variable rotation speeds, the APU continues to generate a certain amount of power.
