3:00 that sound has something to do with the V.S.V (Variable Stator Vanes). Because the engines are on its best above 80% of thrust. So those Vanes turns below the 80% thrust to make sure all incoming air will have the max performance as higher compression, less speed etc. My teacher could explane it better so sorry guys if you dont understand it ;)
@@SOUTHENDAVIATION indeed, but its manageable. For gasturbine engines (M15) is my last grade an 8. So i think for someone who didn't has the highest education at highschool tis wouldn't be that difficult.
@@jouniairplanevideos Further on to this discussion, as this howl has always fascinated me, Variable Stator Vanes were new to me when you mentioned them so I assumed that these were unique to the GTF. I did some further research on VSV's to find out a good few engines have them, CFM56 for example which has no Vulcan howl like the GTF does. One conclusion I did have was maybe it's the gear ratio which helps the howling noises? The fan rotates at a third of the speed as the HP and LP compressors. So I wondered is the howl created by the sudden acceleration of air once it enters the compressor stages?
I don’t think it’s due to the Variable Vanes. All digital engines has Variable Vanes. I worked on PW engines before and this howling sound is quite normal when the engine spools up to part power - 80%. It’s something got to do with newer engines, when the turbine blades are cutting into the outer seals. I might be wrong but this answer is best to be answered by OEM themselves.
Indeedy, the NEO with PW1000s sometimes does it but it's sort of hit n miss. I think it's to do with the Engine being larger means it's less common on the NEO?
GE90 drinks fuel man….. compared to PW4000, PW is worse. But GTF is a whole different game play…lesser parts, lesser stages, lighter and most important, lower maintenance cost.
Essentially yes that's what it is. What folks want to know (at least I did) was what exactly was causing the noise, not necessarily what the sound was.

Just goes to show how advanced those engines are!

@@SOUTHENDAVIATION good question, this is something I don't know exactly. I need to ask it my teacher myself.

Beautiful. The Embraer 190 with these big engines looks like a 777 little brother.
2:59 whale sound! ❤️
Wow, the gearbox really makes the engines quiet!
That’s worth 20yrs of research to make it work man…
The E190 and the A220 with the PW GTF has the whale mating calls and I love it. The A320Neo with the similar engine doesn’t really make this noise.
Indeedy, the NEO with PW1000s sometimes does it but it's sort of hit n miss. I think it's to do with the Engine being larger means it's less common on the NEO?
Neo has it
the WHALE SOUND at 3:00
2:52 - Here in Brazil we call it the sound of the whale.
A Embraer se superou com o E190 avião de linhas elegantes belas asas e um motor enorme que dá um certo charme à aeronave, linda máquina ❤
Very nice up close video of the Wideroe E190-E2 at Southend, great sound as well
3:00 Whale Sound
No one asked but cheers 👍
Linda máquina brasileira. Parabéns Embraer.
I like P&W ,powerfully sound 💪
Absolutely fire footage mate! That spool-up sound was incredible!
Thanks mate, yes I adore those engines!
Very nice sound and E290
With those huge engines that really give it a high power to weight ratio
That howl tho 🤤 great vid mate!
Love seeing the huge engines on a smaller airframe, these and the A220-300s look so mean
🐋 sound. Beautiful ❤️
Sounded brilliant hope they stay at SEN
Wao , That P&W engine are nice and quait it !!!.
That’s amazing I was at Southend yesterday and we saw a few amazing content keep it up 😀
Those engines are nearly as wide as the fuselage!
Orgulho dos brasileiros!
PARDO BURRO ACHAR AR ISSO ORGULHO....LOL
Whale sound amazing
Belo vídeo, lindas imagens.
beautiful plane, whale sound
Awesome Video
This engine have a "whale sound"...beautifull
It totally reminds me of the GE90
GE90 drinks fuel man….. compared to PW4000, PW is worse.
But GTF is a whole different game play…lesser parts, lesser stages, lighter and most important, lower maintenance cost.
@@ivtec74 I'm talking about the engine sound-
E2 the best
(EMBRAER) EMPRESA BRASILEIRA DE AERONÁUTICA
So good noise...
This plane is a best seller from Embraer....
the engines are so quiet
Nice vid!
Thanks!
It is just singing the blue whale song.
Those engines are just to big😁😁😁😁
P&W say it's low power transient combustor tone.
Essentially yes that's what it is. What folks want to know (at least I did) was what exactly was causing the noise, not necessarily what the sound was.
PW1900G engine not PW1000G engine😊
3:00 "The whale chant"
The whale's sound🐳
This will rattle a few teacups on the Marine Estate methinks!

Nice vid!
