  • Publication number: 20240003302
    Abstract: A compressed air supply system includes: a bleed air passage; an auxiliary compressor structure including a compressor inlet and a compressor outlet, the compressor inlet being fluidly connected to the bleed air passage; a supply passage which is fluidly connected to the compressor outlet and through which compressed air from the auxiliary compressor structure is supplied to an air cycle machine; an accessory gear box; and a continuously variable transmission structure that changes speed of rotational driving force output from the accessory gear box and rotates the auxiliary compressor structure. The continuously variable transmission structure and the auxiliary compressor structure are fixed to the accessory gear box, and the accessory gear box is fixed to the gas turbine engine.

  • Publication number: 20240003293
    Abstract: A compressed air supply system that extracts compressed air from a gas turbine engine and supplies the compressed air to an air conditioning pack of an airframe. The compressed air supply system includes: a low-pressure bleed air port that extracts compressed air from an upstream side of a high-pressure compressor; a high-pressure bleed air port that extracts compressed air from a downstream side of a front-stage portion of the high-pressure compressor; a main pipe extending from the low-pressure bleed air port toward the air conditioning pack; an auxiliary compressor that is located at the main pipe and increases pressure of the compressed air; a high-pressure bleed air pipe that couples the main pipe to the high-pressure bleed air port; a high-pressure bleed air valve located at the high-pressure bleed air pipe; and circuitry that opens the high-pressure bleed air valve when the circuitry determines that an insufficient pressure state occurs.

  • Publication number: 20230407794
    Abstract: A core engine including a core casing covering a low-pressure rotary structure and a high-pressure rotary structure and includes a passage of air flowing through the low-pressure and the high-pressure rotary structures; a fan located in front of the core engine; an inner cowl serving as an inner peripheral surface of a bypass passage that extends through the fan and bypasses the core engine; an accessory gear box that extracts power from the low-pressure or the high-pressure rotary structure and supplies the power to accessories; an auxiliary compressor attached to the accessory gear box, is driven by power of the accessory gear box, and increases pressure of compressed air extracted from the core engine; and a compressed air pipe that extends through an inside of a strut connecting the core engine and an airframe and supplies the compressed air having an increased pressure by the auxiliary compressor to the airframe.
