Rolls-Royce Engine Water Ingestion Test

How does the water bypass the combustion?

- @ fryloc359 - The fan portion of the engine is much larger than the engine itself. Water, for some reason actually improves efficiency in some way. Here, they're putting in thousands of gallons per minute. Other good videos are; 'blade off test' where they blow a portion of the turbo fan blade off to see if the engine shroud can contain the damage...and 'bird ingestion test' where they fire frozen chickens and turkeys in the engine to analyze damage to the fan. (more in next post)

For the record, they fire raw/thawed birds...if you're going to nail an avian creature inflight, it's probably not going to be frozen, hence, it wouldn't make sense to blast rock-hard feathered friends into them ;)

Water reduces the temp in the turbine allowing more fuel and therefore more thrust! Old low bypass and turbojets use water and methonal for this purpose!

(continued) They test things like this so they can see where points of failure will occur. If part of the blade came off and went through the fuselage, obviously that would be bad... Only a few have been unfortunate enough to get sucked into the turbo-fan by standing too close. The result is immediate evisceration...e.g. they're ripped apart and the only way to identify is through DNA. (sorry to be graphic). Testing and running engines such as these require a great amount of safety.

I've seen the bird and sand videos, and a few cutaway jet engines. I just never looked that closely to see how water could get around the compressor and combustion chamber. the thing about water and efficiency is that in car engines at least when combustion occurs the water turns to steam which expands, giving you a bit more energy. I suppose that since the water displaces a bit of air it would raise the compression a bit, which would also give a bit more energy.

It goes straight through.

wouldn't that blow the engine out? I.e extinguish the flames?

no, it's bypassed

hey i`m just playing the fool.
