Aero Jet Wash, LLC presents an on-wing washing system using injected water or detergent which penetrates deep into the engine, cleaning performance stealing contaminants.
The Aero Jet Wash cleaning process is superior in terms of its cleaning efficiency and matchless environmentally friendliness. With the Aero Jet Wash process there are no harsh effluents blown out into the atmosphere. The newly developed Collection Suit recovers the fluids used in the wash, along with the poisonous effluent they clean from the engine. Best of all, this is accomplished in a fraction of the time taken for traditional engine wash events.
The Aero Jet Wash’s Collection Suit has been carefully designed and tested to be used in all U.S. and international airports and maintenance facilities with the environmental concerns in mind.
It is the revolutionary Aero Jet Wash’s Collection Suit that has changed the face of engine washing in the industry. Accomplishing engine washing in a fraction of the time traditional engine washes take, this new method can be accomplished virtually anywhere the aircraft is parked.
"We not only bring the wash to the aircraft, but we do so in the hangar (for most engines), on the ramp or at the gate." reports the Managing Director of Aero Jet Wash, LLC.
ENGINE WASHING MADE FAST AND EASY
Engines can be washed in as little as one quarter the traditional wash time (approximately 30-45 minutes) using as little as 5-10 gallons/minute, depending on the size and make of the engine. With multiple-engine cleaning capability, a commercial twinjet can be cleaned in approximately 1 hour at the end of the flight day. Even more convenient this can be done virtually anywhere; even inside the hangar for most engines. The service is typically offered overnight, while the aircraft is parked at the gate. Another benefit is that the wash procedure can be done with one technician.
HOW IS THIS ACCOMPLISHED?
Initially maintenance personnel perform the pre-wash preparation procedures as instructed in the appropriate engine manuals. The engine lines are disconnected, capped off and prepared by maintenance crew according to manufactures’ specifications manual(s). Once the preparation is completed the Aero Jet Wash equipment is brought to the aircraft.
The injection cart contains everything needed to wash the engines. The Aero Jet Wash Collection Suit is placed over the engine cowl, and the J-Hooks, which inject the water/detergent straight into the core of the engine, are attached. The injection cart that features storage tanks for de-ionized water/detergent and expelled effluent provide water for cleaning and a collection system. The entire procedure is completely controlled from fluid injection into the engine to recovery as the effluent is discharged.
The system consists of the injection cart, nozzles, and the Collection Suit (collection system) and the waste water collection unit. The AJW 115 (Green Jet Wash®) injection cart is a completely self contained system for supplying de-ionized water (hot or cold) for the cleaning procedure, and a collection system that is designed to capture and contain the effluent. This injection system is able to supply cold or hot water/detergent upon demand. The J-Hook installation makes it possible for the personnel washing the engine to deliver water/detergent into the engine without losing any to the bypass. For areas where power is not readily available, an auxiliary generator is used to power the cart.
The Collection Suit is a one piece special fabric enclosure that fits over any aircraft engine. The enclosure is water proof, and when installed it becomes water tight. Once the suit is in place the collection system is connected and the Aero Jet Wash system is ready to be used.
AJW asserts that because pure water is used in place of the previous harsh chemicals used by the industry, there are no adverse effects to the engine gaspath coatings and sealants. This is an especially important consideration for hot section components that may have expensive thermal barrier and corrosion resistant coatings.
Additionally, there are no poisonous mists sprayed into the atmosphere, and the technicians are subjected to no hazardous environment.
The engine is rotated, using the electric starter motor, to about 20% of its idle speed, and the water is injected through the J-Hook into the engine. Our company stresses that conventional washing methods are not as effective due to the use of denser washing mixtures which, when sprayed in the front of the engine, are partially centrifuged out into the bypass fan duct and never reaches the critical gaspath components.
This engine wash process is applicable to all turbine engines. The adjustable nature of the J-Hook and universal fit of the Collection Suit are designed to fit just about any engine size.
COMMON BENEFITS FROM AERO JET WASH SERVICES
- Recovered EGT margin
- Increased Fuel Savings
- Prolonged Engine life
- Lower maintenance costs
- Reduction in pollution
- No interruption to flight schedules
- Performed in or out of a hanger environment for most engines
- 100% environmentally friendly
In the recent past, wet washing engines resulted in the expelling of contaminants indiscriminately upon the ground. Too often this hazardous waste would then find its way into the local water systems.
However, the Collection Suit contains all the contaminants and it is then cleaned and disposed of, thus satisfying all EPA requirements for the proper handling of hazardous waste.
