Engine Compressor wash
Did a search on compressor washes, but only came up with plane spotter type info.
Can anyone give a link to the procedure for a compressor wash on a med to large turbofan engine. ie how its conncected, where, how it cleans the blades and removes what I would think was baked on contaminants.
Was asked a question today about it and couldnt give more than a basic answer.
An aditional question from myself is, to large jet engines have a gallery fitted as part of the engine for such compressor washes. I did notice a compresor was clip on youtube that showed a Citation with a hose pointed at the N1 fan.
Can one overdo compressor washes, ie if you did one after each flight, can it actually damage the engine.
Also, does any one know if this is fact or fiction. years ago I was told that the for the Mirage 3, several kilos of crushed walnut shells was thrown down the intake as the engine was dry spun. The shells being abrasive enough to remove the contaminants, but soft enough to do damage.
