very good demonstration - clearly the GTF is much quieter, really very impressive. Gives Better understanding of its benefits & much more confidence that despite some current problems the GTF has a bright future.
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.
Wow, the GTF is nearly silent. The buzz saw sound coming from the CFM is the tips of the bypass fan breaking the sound barrier. This causes huge stresses that need to be mitigated. The gearing allows larger but slower moving fans that increase efficiency.
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
@@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.
That sonic resonance from the talon x combuster of PW 1000 ❤ #whalesound this quieter geared engine is the result of a 20+ year-long research of nasa and PW. Amazing!
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
A few days ago I flew on an A321 neo with Pratt & Whitney, sitting in row 5. You can hear the friction of the air on the fuselage much more than the engines.
As an avgeek the cfm engines sound glorious. As a passenger, though, I prefer the P&W engines by a longshot. That droning stops being music to the ears once you have to listen to it for multiple hours nonstop.
Great video! That GTF sounds like a watered down version of a PW4000 from a 777! Of course! That's the main point of GTF! The fan spins slower than the compressor; therefore it requires less fuel.
As much as I love the roar that older turbofans put out due to the blade tips breaking the sound barrier, it's nice to just hear the singsong of the engine core.
@@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.
@@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.
P&W hands down. Dam thing sounds like it’s still at idle. Prefer smooth & quiet over the buzz saw any day. That’s the same Buzz saw sound the 737 makes.
Besides the engines' sounds, there's an interesting difference in how the pilots flew their respective vessels: ===CEO=== Just over a minute after applying TOGA thrust, pilot reduced engine power to climb thrust. Next, after about a minute and a half, pilot retracted slats. ===NEO=== Pilot applied TOGA thrust, retracted slats after 2 minutes, and then kept TOGA thrust all the way until the video cut to the next segment I'm guessing the NEO aircraft was heavier at the time and thus needed full TOGA thrust for a longer time to safely climb up.
@@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.
When I get in a plane and start hearing whale noises. No no no. WAIT WAIT WAIT. I just wanted to fly with the cfm56/leap instead. Just because I've spent years with the cfm56. The pratt is impressive very quiet. Ascend Flightglobal found that the LEAP had an engine dispatch reliability (EDR) of 99.4%, while the PW1100G had an EDR of 98.4%.
it is really not fair : you compare a new PW engine with the last CFM engine configuration (CFM56-5B) - please do the same with the new CFM engine : LEAP-1A and we will see (heard :-) )
The new PW GTF engines maybe quieter and more efficient but the CFM56 is ultra reliable. As with most engines from GE (joint venture) it has Toyota like reliability. Even the new LEAP engines are proving to be more reliable than the PW GTFs.
@@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

I love the old racket that the A321 CEO makes, but The NEO is definitely alot quieter

Silent is worser, I like sounding engines
The sound of that CFM-56 at takeoff thrust gives me a hard-on!!!

@@yolo_burrito it is more efficient if they can stay on wing long enough
Nothing like the best PW G1100 , powerful , efficient , quiet ✈️
Nowadays they have some “Minor” issues but they will fix it for sure 🤗

Wow. Very different. The CFM engine has that buzz sound that compared with the NEO’s engine is just more annoying. Very quiet PW geared turbofan.
the PW1000 can buzz

Just think about how much of an improvement these engines are over the howling turbo jets on the early jet liners like the Boeing 707. DC-8
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
in 8:45, that sound is the signal of Pratt & Whitney Engines
RR also does this. Trent 500, Trent 700. The classic whale noises.

so smooth sound for pw1100G , amazing design!
Звук двигателя PW просто кайф. Я недавно летал и влюбился в этот шедевр.
It's like F1 switching from v8 to v6. The new sounds quieter but less exciting.
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.

impressively quiet
Defenetely going for the CFM here good old calming buzzsaw sound. The PWs just sound annoying imo. Though of course it’s personal preference.
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.

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.
A321Ceo - Cebu Pacific
Noisy but reliable and at least it works!
you can hear a faint buzzsaw from the neo at 13:20
I didn’t hear it, but hill kept trying
I didn't hear
Judging By The Sharklet Wind Stabilizer That Airline Is Cebu Pacific
geared turbo fan looks bigger and sounds quieter.
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.
I like both!
I'll forever stick with CFM56
CFM56 not fuel efficent
In comparison to the PW1100G , the CFM56 sounds like an upright vacuum cleaner with a coin stuck in the belt drive. 🤔🤫🤔
Tru

Quieter, Lower Pollution and Fuel savings.
I can hear a howl on PW1100G 8:43
It's annoying sounds like a sick whale or a cow suffering in pain
Big difference!
8:44 sounds so much like an A220 lmao
ill choose NEO rather than CEO
I prefer the CFM LEAP over the PW1100G on the A321neo
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?

Agreed
My favorite is the CFM Leap 1A-32. Love that bassy startup hum and the spool up sound.
oh yeah how can I miss the whale sound of the pw1100g
I love cfm56 engine sound loud
Same here I also love it more over then the IAE V2500'S CFM56 Is definitely better
The sound of the PW1100G! 😍
PW howls like its an Avro Vulcan! 8:44
Combustor resonance.
The P&W engines are Much quieter, shame you couldn’t compare the old CFM with the New CFM Leap

CFM Sounds like razor
What airline is this
Cebu pacific i think
PW for the win
Funny...the gee whiz GTF has about 3000 engines that are NOT anywhere near the LEAP when it comes to reliability. Not even close.
8:43 if you hear this then your aircraft has PW 1100G engines LOL
ROARRRRRRRRRRRRRR
GTF is significantly quieter!
The Pratt engine sounds better
incase your wonderwering what airline is this its cebu pacific
Wondering, not wonderwering
