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 4 ай бұрын

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 Ай бұрын

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 20 күн бұрын

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.

But yes it is not an artificially created chemicals for altering the atmosphere as the conspiracy theorists believe it to be.

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.

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.

@thatmitchellguy7687 5 ай бұрын

@@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🤷🏾‍♂️

It’s the two runs with the hose and then one without to dry.

@justanotherperson2960 5 ай бұрын

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.
