Abstract: A wash unit for washing a gas turbine compressor include a wash fluid delivery system for injecting wash fluid into a compressor; one or more sensors for indicating one or more of wash fluid levels, temperature and quality; a unit controller for receiving information from the one or more sensors and controlling one or more components of the transportable wash unit; and a mobility unit for mobilizing the transportable wash unit.

Abstract: An engine wash system includes a manifold for delivering wash liquid to an engine. The manifold includes an internal engine contour segment shaped to correspond with at least a portion of the engine case at the inlet; a wash delivery segment connected to the internal engine contour segment which follows the engine case curvature in an axial direction and hooks around an outside of the engine case at the inlet; an inlet on the wash delivery segment to receive wash fluid; a nozzle on the wash delivery portion directed to spray into the compressor inlet of the engine; and a guide extending from the pipe and shaped to align the manifold with respect to the engine so that the nozzle sprays into the engine aft of the inlet particle separator.

Abstract: An engine wash system with a collector includes a collection pan with a base angled toward a centerline and first and second panels rotatably connecting to first and second sides of the collection pan; a plurality of wheels connecting to the base; a first support connecting on a lower end to the collection pan and extending vertically upward from the collection pan; a first funnel connecting to the first support; and a first hose connecting the first funnel to the collection pan.

Abstract: A transportable wash unit comprises a wash fluid delivery system for delivering wash fluid to a desired washing location; a power supply for providing power to components of the transportable washing unit; a unit controller for controlling one or more components of the transportable wash unit; and a mobility unit for mobilizing the transportable wash unit.

Abstract: The disclosure relates to a maintenance unit for servicing aircraft during stand-still, comprising electrically powered service and/or maintenance equipment. There is a power input for connecting the unit to an electrical power supply operating at 200/115VAC at 400 Hz. The unit further comprises a transformer and conversion unit (TCU) for transforming the 200/115 VAC/400 Hz power to standard grid voltage at 400/23OVAC at 50 Hz and at least one frequency converter enabling variable frequency of the output voltage, for powering said service and/or maintenance equipment. The maintenance equipment may be a gas turbine engine washing equipment and comprises a water delivery member for supplying water from a water source, a high pressure pump coupled to the water providing means for providing pressurized water, and a high pressure water outlet connection for connecting cleaning devices.

Abstract: A spray cleaning device for cleaning an auxiliary power unit (APU) within an aircraft comprises one or more spray nozzles, a water tube for supplying water to the nozzles, and positioning means. A system for cleaning APUs comprises a spray cleaning device and a supply system for providing pressurized and temperature controlled washing fluid to the cleaning device. A method for cleaning APUs comprises providing a spray cleaning device, attaching the cleaning device to an air inlet structure of an aircraft, and supplying washing fluid to the cleaning device at a desired spray pressure, spray temperature, and spray droplet size.
