Hosepipe Assisted AN24 Startup?

Thu Jul 08, 2010 9:49 am

Never saw anything like this before, the guy is pointing a hosepipe at the engine during startup.
Is this really for cooling during startup as the photo comment suggests?

Probably just doing a water wash on the engines. We were required to do a desalination rinse on our aircraft if operated within a certain distance and altitude of salt water at the end of every flying day.

I think the photographer's comments...Chita is not near a marine environment... it would appear the an AN-24 is difficult to start at 41C (106 F)... had a truck like that had to cool the starter on hot days

Assuming ITT (or TIT or whatever Antonovs use) is the limiting start parameter on a hot day, is it an attempt to get the water into the compressor and all the way down the gas path to keep the temp below limit?

It looks like an attempt to increase the mass flow of air into the engine by cooling the air with water, something like the water injection on the spey engines fitted to the BAC 1-11.
