A turbine engine fleet wash management system is configured to electronically communicate with a turbine engine system, a fleet management service, and a cleaning management service. The turbine engine fleet wash system causes a cleaning of a turbine engine to occur based on information received from the turbine engine system and other sources. The turbine engine fleet wash management system includes a cleaning schedule optimizer that generates a cleaning schedule based on engine health monitoring data, engine operation data, maintenance schedules for the turbine engine, and cleaning regimen data. The cleaning schedule optimizer estimates turbine engine performance improvements based on the selected cleaning regimen, and calculating an estimate of carbon credits earned based on the predicted improvement in turbine engine performance.

A method for performing a cleaning cycle on a turbine engine mounted to an airframe includes conducting a cleaning agent from a cleaning agent supply into the gas turbine engine. The method further includes conducting compressed air from a cleaning air supply into the gas turbine engine to dry motor the gas turbine engine while the cleaning agent is conducted from the cleaning agent supply into the gas turbine engine.

Aircraft engine cleaning system

Wands are used as parts of cleaning systems to conduct cleaning agents into gas turbine engine cores. Wands according to the present disclosure include inlet assemblies adapted to connect to cleaning agents, dispensers adapted to discharge cleaners into gas turbine engines, and conduits that extend from the inlet assemblies to the dispensers.

Wands for gas turbine engine cleaning

A cleaning system for performing a cleaning cycle on a turbine engine mounted to an airframe includes a mobile supply unit. The mobile supply unit includes a cleaning agent supply that introduces cleaning agent into the turbine engine. The aircraft includes at least one valve configured to block cleaning agent from moving from the turbine engine into a passenger cabin of the aircraft.

A turbofan gas turbine engine for use in an aircraft includes a fan, an engine core, and a cleaning system. The fan and engine core cooperate to provide thrust for an aircraft when in use but may suffer performance degradation when dirty. The cleaning system is configured to conduct a cleaning agent from a supply into the turbofan gas turbine engine to clean the turbofan gas turbine engine.

An aircraft comprising a cabin air system, a gas turbine engine including an engine core coupled to the cabin air system to provide compressed bleed air to the cabin air system and a cleaning agent supply connector coupled to the engine core to conduct a cleaning agent to the engine core, and a pneumatic coupling system including a first valve coupled between the cabin air system and the engine core, a second valve coupled between the engine core and the cleaning agent supply connector, and a controller coupled to the first valve, the controller configured to automatically close the first valve and block compressed bleed air that may contain cleaning agent moving through the engine core from moving into the cabin air system in response to receipt of an input associated with a cleaning cycle.
