Water injection used to be used in older turbo jet engines for a boost in power.

[@rfvtgbzhn]

Yes, it increases the temperature difference within the engine, which increases it's Carnot efficiency.

​@@rfvtgbzhn The >800-fold expansion due to the phase transition probably doesn't hurt with thrust either.

[@wormbo2]

​@@xitheris1758is this basically "water into hot place =steam? And the volume expansion of said steam adds thrust?

[@dukecraig2402]

​@@xitheris1758 If you're talking about the water expanding into steam then yes, that's part of how it works, by adding thrust from the water expanding into steam but that's still only part of it, there's people here in the comments that are arguing that military jet aircraft like the B52 that used water injection to take off heavy from shorter runways had turbo jet engine's and these are turbo fan engine's that are different, true but the fact is even though they operate somewhat differently water injection has still been used on turbo fan engine's, Air Force One has the system fitted on it's engine's so the President can get out of Dodge that much quicker, some KC-135's also have the system fitted on their engine's for heavy take off's and even some turboshaft engine's have used it like the top secret Hughes 500P helicopters dubbed "The Quiet One's" that were secretly modified for a top secret CIA mission into North Vietnam during the Vietnam War had water injection for emergency power. If you've never heard of that one do yourself a favor and Google "The Quiet One's Helicopters", it's a story that between all the skullduggery used to keep the special modifications made to the helicopters to make them quiet a secret in America during it's development it's as comical as it is fascinating and is the kind of thing that would make a great movie.

[@Hopeless_and_Forlorn]

Actually, rain water can shut down a jet engine in flight, which is why the engine ignition is usually turned on during flight in rain. The early model of the CFM56-3 engine was susceptible to flameout in very heavy precipitation. A redesign of the fan spinner and a higher N1 idle speed were required to fix the problem.

[@h8GW]

Also, larger diameter fans mean more centrifugal force, which means heavier particles, like water droplets are more prone to get thrown outwards towards the bypass ducts. It's the same principle as on a cyclone vacuum cleaner.

[@tadferd4340]

Continous Ignition is mainly a precaution. Airliner turbofans are water tested and must maintain operation while ingesting heavy amounts of water. Planes with older engines sometimes had a water injection system to inject water into the turbine core to boost thrust. There were cases with older engines flaming out from rain and hail, but those tended to be in non standard configurations or had other contributing factors. Designs have improved and it us extremely unlikely for water ingestion to cause a flame out. Still, there is no reason not to be safe, just incase. Hence, continuous ignition.

[@SidestickPilot]

The amount of rain you’d need to truly drown out a modern turbofan is ludicrous. We are only instructed to use continuous ignition if it’s heavy rain. There’s more of a chance the igniter is flamed out due to lightning. Even then the FADEC will sense a flameout either partial or completely and command both igniters to fire continuously.

[@weerolein]

​@@h8GWthere are nearly no centrifugal forces on the airflow through the engine as the air doesn't co-rotate with the blades.

[@louisbeerreviews8964]

Nope

[@Rick_Sue0601]

Funny, the B-52 bombers models D-G use water injection for thrust

[@patricklenigan4309]

Well, those are turbojets, and the injection system is built directly into the design and finely tuned to perform its job properly

[@Rick_Sue0601]

Turbojets? They’re J57s & yes the demineralization of water used for injection for thrust. Commercial engines are turbofans

[@Idrinklight44]

Has something to do with cooling down everything

[@complexdevice]

It is indirectly related to thrust. The water injection system lowers combustion temperatures and thus allows the engines to operate at a higher power setting for longer. This is why the B52s exhaust is so smokey on takeoff.

[@MaddogMike-444]

KC-135 tankers do this too for extra thrust on takeoff.

Granted, what goes in also goes out, but when you burn jet fuel with oxygen, you get carbon dioxide and high temperature water vapor (steam).

[@menjolno]

strawman argument 😡

[@atlanciaza]

Technically you are right and wrong, because water is a chemical, as it consists of matter that has interacted and formed a compound, which is the definition of chemistry. Also the fuel used, has water vapour as a byproduct, so the chemistry even happens during operation, so some of the water vapour is not from the atmosphere itself but from the fuel combustion process. But yes it is not an artificially created chemicals for altering the atmosphere as the conspiracy theorists believe it to be.

[@tartufo4870]

Nice work 👏 👌

[@rolandotillit2867]

Water actually helps the efficiency of the fan, because it reduces the gap between the fan blades and the housing, as the water is flung out.

[@thatmitchellguy]

Yeah, that’s not how that works 😂

[@rolandotillit2867]

@@thatmitchellguy and yet it does.

[@thatmitchellguy]

@@rolandotillit2867 Please explain, I’m curious. Since the gap between fan blades and the fan case is no greater than .80 of an inch and decreases during operation due to centrifugal force and heat, hence the purpose of having rub strips/seals between the case and the fan for that purpose. Or are you talking about the compressor where the clearance is a lot tighter? Or let me guess you’re talking about the gap between each of the fan blades itself? The same gap that will never change due to the locking of the mid-span shrouds? 🤔 Guess you never disassembled and engine or troubleshot temperature trends before huh? And the fan is free floating driven from the rear by hot gases of the HPT via the LPT, how would water make the fan efficient? But please, tell me more, this MFE vet would love to know.

[@rolandotillit2867]

@@thatmitchellguy Because by reducing tip to hub clearance you get less separation in the fan blades. It's like lowering the ride height on a car.

[@thatmitchellguy]

@@rolandotillit2867 well for starters, that’s a bad analogy to use when talking jet engines considering that lowering a car’s height is that you’re lowering the frame in relevance to the hub. Speaking jet engines in that analogy the fan’s rotor would be the hub and the blades would be the tire, clearance change from the fan to the casing would be by you adjusting the casing‘s clearance and relevance to the fan. However, that’s not how clearance is achieved. But back to the matter of hand, the fan blades are attached to the rotor which is fixed and balanced and rainwater is not changing the clearances of the fan compared to casing. I’m not sure who’s feeding you that or led you on a wild goose chase but that’s not how clearances work and how water is processed through the engine. I’ve done plenty of runs in the rain, compressor washes and my fair share of teardowns, somebody led you astray. But to each its own🤷🏾‍♂️

[@alext8828]

Only place to learn such things. Bravo!

[@thatmitchellguy]

One thing the video doesn’t clarify, is the difference between low bypass and high bypass turbofans. High bypass turbofan the majority of any water that got sucked in would go through the bypass because 80% of it’s airflow is all bypass whereas the other 20% is core flow so in theory, most of the water would end up in the bypass. Low turbofan though, the majority of the water is going through the core, and the end result is usually just lower EGT temperatures. It will take a massive volume of water ingested at one time being ingested to cause a problem which most likely would be a compressor stall. And most washes, the water is usually introduced through dummy ports or fan discharge temperature sensor ports (after the fan stage) because the primary focus is washing the last several stages of the compressor, high pressure turbine/nozzles, low pressure turbine/nozzles, and combustion chambers because that’s is where the majority of carbon build up happens. The objective is to maintain proper cooling airflow, prevent hot spots, and increase the engine’s time on wing.

thats not quite how that works. the system that adds water to the engine does so only to decrease engine temps which allow even more fuel to be used for limited amount of time (almost exclusively on takeoff) the water itself also does slightly increase thrust when this is done but thats because its more mass being thrown out of the exhaust. if you attempted this process w/o sufficient water flow the engine will fail on. this has happened before.

[@justanotherperson2960]

The infographic shown is partly wrong. Worked as an engineer who analysed performance and stress of RR Trent engines. Water from rain is ingested by core stage (bypass stage is outside the core) as well and is completely ok, as the thermal efficiency is barely affected by this. What matters is the pressure, and if the pressure is maintained in the initial stages (compressor), the combustion occurring in the combustion chamber can easily surpass the surface of the sun (temperature wise). Pressure and temperature is directly correlated. Bypass has got nothing to do here.
