nachomaga Posted July 30, 2018 Posted July 30, 2018 Not sure if this procedure has disscused before, but anyone know what is the purpose of pour water in the intake (I suppose is water)? Just for cooling down? Or is the italo-american way to add water in the engine instead the switch? ;) Full article here, interesting btw: https://theaviationist.com/2018/07/30/italian-navy-av-8b-harrier-jet-deploys-aboard-wasp-class-amphibious-assault-ship-uss-iwo-jima/
Marcus763 Posted July 30, 2018 Posted July 30, 2018 Hmmmm perhaps fresh water to wash away corrosive salt water ?
Retu81 Posted July 30, 2018 Posted July 30, 2018 Ever wondered how a jet engine is washed? That's how they do it. You spray in clean water and have the APU/Starter turn the engine.
TrigaNZ Posted July 31, 2018 Posted July 31, 2018 (edited) I would suggest this is a simple way of washing out the salt from the fan area. Water won’t be making it into the engine core if the engine is running. A proper engine wash is usually piped in through a Port/Tap/Valve so it can get into the compressor/hot section and often includes a chemical wash. Edited July 31, 2018 by (C/229) Kiwi
Zadren Posted July 31, 2018 Posted July 31, 2018 This is a compressor wash going on here. The Pegasus sucks in a lot of salt. The engine is dry-cranked, and a cleaning solution is hosed into the intake to wash the gunge out of it.
nachomaga Posted July 31, 2018 Author Posted July 31, 2018 Thanks for the input, guys, didn’t think about the salt.
joey45 Posted July 31, 2018 Posted July 31, 2018 You also notice it is chained down. The only way to make sense out of change is to plunge into it, move with it, and join the dance.

Zadren Posted July 31, 2018 Posted July 31, 2018 You also notice it is chained down. Yeah, quite. Tie-down run, and comp-wash. Standard. :thumbup:
TrigaNZ Posted July 31, 2018 Posted July 31, 2018 Looking at the flow of water out the cold nozzle and the lack of water out the hot nozzle I would say the engine is running. A dry crank would not produce that much airflow.

A dry crank would not produce that much airflow. Having spent some considerable time standing on, in and lying under Harriers while they are operating, I must respectfully disagree. If that engine was running, the guy with the hose would be on the way to a really bad headache. :huh:
dopebogey Posted August 1, 2018 Posted August 1, 2018 (edited) Ya, they are just windmilling the motor to get rid of the salt and other crud that is built up. Some aircraft have special attachments that attach right on the intake and spray detergent then wash it out with water. It's not just Harriers they do this to. Edited August 1, 2018 by walleye62
