    Abstract: Bleed air systems for use with aircraft and related methods are disclosed. An example apparatus includes a compressor having a compressor inlet, a compressor outlet, and a first drive shaft. The compressor outlet is to be fluidly coupled to a system of an aircraft that receives pressurized air, and the compressor inlet is to receive bleed air from a low-pressure compressor of an engine of the aircraft. The example apparatus includes a gearbox operatively coupled to the first drive shaft to drive the compressor. The gearbox is to be operatively coupled to and powered by a second drive shaft extending from the engine. The example apparatus also includes a clutch disposed between the first drive shaft and the gearbox to selectively disconnect the first drive shaft from the gearbox.

    Abstract: Thermal management systems incorporating shape memory alloy (SMA) actuators and related methods. A thermal management system includes a heat transfer region, a process fluid conduit, a thermal management fluid conduit, and an SMA actuator assembly. The SMA actuator assembly includes an SMA element coupled to an actuation element, which is configured to assume a position among a plurality of positions defined between a restrictive position and an open position. The position of the actuation element is based, at least in part, on a conformation of the SMA element. A method of passively regulating a temperature of a process fluid includes conveying a process fluid stream in heat exchange relation with an SMA element, transitioning the SMA element to assume a conformation, flowing each of the process fluid stream and a thermal management fluid stream through a heat transfer region, and modulating a flow rate of the thermal management fluid stream.

    Abstract: A fan air modulating valve (FAMV) employs a pair of doors rotatably attached at the fan bypass air exit of a precooler. An actuator engages the doors for simultaneous rotation through a range of motion from a first closed position to a second open position, wherein trailing edges of said doors sealingly engage an exit plenum extending from the precooler in the first closed position and fan bypass air flow is modulated by positioning the doors within the range of motion between the first and second positions.

    Abstract: An example system for providing mechanical power to an aircraft accessory with a turbine engine, where the turbine engine includes a low-speed spool and a high-speed spool, includes an accessory gearbox disposed between the low-speed spool and the high-speed spool and a clutch disposed within or external to the accessory gearbox. The accessory gearbox is configured to drive the aircraft accessory, and the clutch is configured to enable either the high-speed spool or the low-speed spool to provide mechanical power to the aircraft accessory via the accessory gearbox.
