CFM56 ON A321CEO VS PW1100G ON A321NEO ENGINE SOUND TAKE-OFF AND MID FLIGHT 

It depends on the engine as well, if you are on a NEO with PW1100 engine then it will be quiet. The CFM is way louder although it uses advanced material, but still it is still a conventional engine. PW engine was designed differently, they incorporated their engine with geared mechanism to achieved the ultra high bypass ratio while maintaining the performance power of the engine. Because of the Gear, they can make the outer fan rotate differently(slower) than the inner fan making it a quieter engine.

Silent is worser, I like sounding engines

do you think that the buzz saw sound from the CFM is because of that? I have no idea, but I don’t really think so… they lose so much lift and generates a big amount of drag if the speed is supersonic

@@xXivanhornetXx It indeed is because of that

The LEAP engine eliminated the buzz saw sound. Leap is better than the overly complicated gtf

@@GAMRMNTS2 better is subjective. LEAP is less complex but also less efficient. The GTF wins in a high fuel cost environment. Right now it’s less valuable but if oil spikes to $200/bbl it will be the preferred power plant.

@@yolo_burrito it is more efficient if they can stay on wing long enough

the PW1000 can buzz

If people are annoyed at the buzz of the engine literally just sit at the back of the aircraft where you can’t hear it at all. Let the people who really enjoy the buzz sit at the front of a plane

Ah but these new engines don't hold a candle to the amazing sound those engines put out.

@@tristarRB211i mean nice engine sound can be pleasing, but if you’re on a multi-hour flight, you just want them to be as quiet as possible

So many maintenance problems though...Definitely a rocket of an engine and quiet

RR also does this. Trent 500, Trent 700. The classic whale noises.

True but on airplane you don’t care

If the airline opts for the Leap 1A-32s intead, they are quieter but sound really nice

@@fsdkonjab *most don't care. Some enthusiasts might have preferred loud ones. But me personally, I don't care that much. Also, both switches are similar in other ways. Like cooler, more interesting tech, aimed for higher overall efficiency while not losing performance.

yes but people who are not aviation enthusiasts like us don't like the noise, especially new flyers.

@@DevolanteI’ve flown on A320s with the CFM Leap 1A-32s. It’s a beautiful and relaxing sound. Also CFM Leap series of engines have 3d printed fuel nozzles and they are so reliable.

They have the same engines, basically (or most of them do).

You must be a big Trent fan then. I don't know anyone who can stand the sound of the CFM56 or Trent series of engines. Horrible sounding engines.

@@AB-80X CFM? IAE? RR? even GE? this sound is not limited to certain specific engine but rather the design of the fan blades. I prefer the PW because of engine technology and not really the sound nor silence since the noises all get drowned out once you reach cruising alt.

I'm with you on that I love the buzzsaw CFM56 engines

I’m staying with the PW here. I love the engine howling. Also buzzing is way more annoying.

Same here I also love it more over then the IAE V2500'S CFM56 Is definitely better

CFM56 not fuel efficent

I didn’t hear it, but hill kept trying

I didn't hear

It's annoying sounds like a sick whale or a cow suffering in pain

Tru

There are carbon blades on LEAP but it has no gear so fuel unefficent

@@yangsherienazainalfitri84But it has a better safety then the PW, PW has many problems that caused airlines to ground the fleet.

@@GarlandTexasSpotter2024 Gears jumping teeth?

Diameter is slightly larger, but not that much. It's a 321 after all, so there are some basic limitations to the engine nacelle size.

Combustor resonance.

Agreed

Cebu pacific i think

V2500 is my most disliked engine

Wondering, not wonderwering

@@yangsherienazainalfitri84 sorry i had a bad phone back then.

Manila

NAIA, Manila

eh, i mean the new one is more efficient, is quieter, and has that "whale" noise which i absolutely love, just my thoughts tho

@@Fynnley525 funny thing though is once you're well up in the air, if you're in front of the engine there isn't that much noise difference. Fuel efficiency I couldn't care less about,. And buzz is always better than whale noises XD

only if you are not flying at night

@@calvinrovinescu6166 ))

@@Rasalguul the older 5B engines honestly are quiet in the seats in front of the engine. The extra noise older engines in general make is actually better for sleeping too.
