Abstract: An inlet door state control system for an auxiliary power unit (APU) includes an inlet door configured to allow air into an inlet of the APU. The system also includes an actuator configured to open the inlet door. The system also includes an APU threshold switch connected to the actuator, the APU threshold switch configured to automatically change from an open position to a closed position when a predetermined APU operating condition is met. In the system, the actuator opens the inlet door when the APU threshold switch is in the closed position.

Abstract: Methods and apparatus to vary an air intake of aircraft engines are disclosed. An example nacelle assembly includes a fan cowl and an inlet cowl movably coupled to the fan cowl. The inlet cowl defines a primary flow path and an auxiliary flow path of an intake of the aircraft engine. The inlet cowl moves relative to the fan cowl between an open position to allow airflow via an auxiliary flow path and a closed position to prevent airflow through the auxiliary flow path.

Abstract: A gas turbine engine including a core having in serial flow order a compressor, a combustor, and a turbine—the compressor, combustor, and turbine together defining a core air flowpath. The gas turbine engine additionally includes a fan section mechanically coupled to the core, the fan section including a plurality of fan blades, and each of the plurality fan blades defining a pitch axis. An actuation device is operable with the plurality fan blades for rotating the plurality fan blades about their respective pitch axes, the actuation device including an actuator located outward of the core air flowpath to, e.g., simplify the gas turbine engine.
