Abstract

A system for cleaning a jet engine with a first compressor stage and a second compressor stage comprises a water holding tank, a waterproof cover, and input hose coupled between the water holding tank and the waterproof cover. Further, the system includes a J-hook coupled to the input hose. The J-hook affixes to a front compressor stator of the second compressor stage of the jet engine. To clean the jet engine, fluid from the water holding tank is injected though the input hose and directed through the J-hook inside the engine.

Claims (20)

1. A system for cleaning a jet engine with a first compressor stage and a second compressor stage, the system comprising:

a water holding tank;

a waterproof cover including a waterproof connection at a rear of the waterproof cover;

an input hose directly coupled between the water holding tank and the waterproof connector of the waterproof cover; and

a J-hook coupled to the input hose via the waterproof connection, wherein the J-hook affixes to a front compressor stator of the second compressor stage of the jet engine;

wherein:

fluid from the water holding tank is injected through the input hose and directed through the J-hook inside the engine.

2. The system of claim 1 , wherein the waterproof cover at least partially covers the jet engine.

3. The system of claim 2 , wherein the waterproof cover further comprises an elasticized rim to seal the waterproof cover around an opening on the jet engine.

4. The system of claim 2 further comprising a heating source thermally coupled to the water holding tank, wherein the heating source heats the fluid.

5. The system of claim 1 , wherein the J-hook affixes to the front compressor stator of the second compressor stage of the jet engine through a back of the engine towards a front of the engine.

6. The system of claim 1 , wherein the waterproof cover collects resultant effluent.

7. The system of claim 6 further comprising:

a pump;

a storage container coupled to the waterproof cover; and

a drainage hose coupled between the waterproof cover and the storage container, wherein the pump pumps the effluent from the waterproof cover to the storage container.

8. The system of claim 7 further comprising a filter coupled to the storage container, wherein the filter removes foreign particles from the effluent.

9. The system of claim 1 wherein the waterproof cover further comprises a screen to prevent pressure build-up during the cleaning of the jet engine, yet effluent from cleaning the engine is still collected in the waterproof cover.

10. The system of claim 1 , wherein the fluid comprises water.

11. The system of claim 1 , wherein the fluid comprises water and detergent.
