Benefits of technology

[0008]Accordingly, it is desired to provide a system and a process for washing engines which allows engine operators to clean their engines more frequently without significantly impacting aircraft availability.

Problems solved by technology

Compressor blades and vanes can suffer from the accumulation of hydrocarbon deposits, dirt, salt, and corrosion residues, affecting their aerodynamic performance.
These deposits can increase exhaust gas temperature and fuel use and decrease the engine's surge margin.
Once a deposited contaminant hardens or the amount becomes excessive, then the effectiveness of a water wash becomes reduced or possibly ineffective.

Embodiment Construction

)

[0022]Referring now to FIGS. 1 and 2, there is shown a mobile on-wing engine washing and water reclamation system 10 in accordance with the present invention. The system 10 includes a mobile unit 12 on which there is located a source 14 of cleaning liquid and a used cleaning liquid collection trough or effluent trough 16. The system 10 also includes a second mobile unit 18 on which there is located a water treatment unit 20, a collection tank 22, and a generator 24 for mobile power production. While the trough 16 has been shown as being on mobile unit 12, it could be located on the second mobile unit 18 or on yet another mobile unit.

[0023]The cleaning liquid source 14 may contain water by itself or water mixed with an appropriate detergent. The detergent may comprise any suitable detergent known in the art in any suitable concentration. The particular type of detergent used, if any, depends on the type of contaminants, dirt, etc. to be removed. The cleaning liquid source 14 may com...

Abstract

A system for on-wing engine washing and water reclamation includes a fluid applicator configured to introduce a cleaning liquid containing at least water into an engine while the engine is being operated, a trough positioned adjacent to the engine, and a collection conduit operatively positioned between an exit end of the engine and the trough to collect an air / liquid effluent mixture leaving the exit end of the engine and deliver at least a portion of the air / liquid effluent mixture to the trough. The collection conduit has an outlet that deposits collected liquid effluent into the trough, and further includes a series of diversion plates positioned within the collection conduit to separate liquid droplets from the air / liquid effluent mixture.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)[0001]The present application is a continuation of U.S. patent application Ser. No. 11 / 098,064, filed Apr. 4, 2005.BACKGROUND OF THE INVENTION[0002](1) Field of the Invention[0003]The present invention relates to a mobile on-wing engine washing system having a mobile unit for reclaiming water used to wash the engine.[0004](2) Prior Art[0005]Jet engine efficiencies are reduced due to environmental contamination buildup in the engine components. Compressor blades and vanes can suffer from the accumulation of hydrocarbon deposits, dirt, salt, and corrosion residues, affecting their aerodynamic performance. These deposits can increase exhaust gas temperature and fuel use and decrease the engine's surge margin.[0006]Many operators report good success in performance recovery using water wash procedures on a regular basis. The washing process involves cyclic washing of the engine with large amounts of water and sometimes, a small amount of detergent...
