Abstract: A collection apparatus for collecting waste from cleaning operations performed on an aircraft turbine engine includes a frame structure, a support arm having a first end movably attached to the frame structure and an opposite second end, an actuator device adapted to enable raising and lowering the support arm, a waste storage tank, a duct having an inlet end and an opposite outlet end adapted to be removably connected to the waste storage tank, and a flexible duct portion having a flexible portion inlet end and a flexible portion outlet end. The inlet end of the duct is adjustably supported by the second end of the support arm. The flexible portion outlet end engages the inlet end of the duct in fluid communication, and is bendable both up/down and sideways and is expandable in length between the flexible portion inlet end and the flexible portion outlet end.

Abstract: A collection apparatus is provided for collecting waste water from cleaning operations performed on aircraft turbine engines. It comprises a frame structure having a pivotally mounted support arm. An actuator device is arranged to rise and lower the support arm between an essentially horizontal transport position to an operative position. A flexible duct is provided with an inlet end and an outlet end. The inlet end of the flexible duct is pivotally attached to the support arm so as to be movable around at least a horizontal axis.

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.

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.

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: 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: An apparatus is provided for collecting waste water from cleaning operations performed on aircraft turbine engines. The apparatus comprises a frame structure. On the frame structure a support arm is pivotally mounted. An actuator arm is arranged to raise and lower the support arm between an essentially horizontal transport position to an operative position forming an angle in the range of more than 0° to 90° or less with respect to the horizontal. A liquid separation device is pivotally attached to the support arm so as to be movable around both a horizontal and a vertical axis.
