General Electric CEO: "This NEW Engine Will Destroy The Entire Aviation Industry!"

Over the past decade, both Boeing and Airbus have upgraded the engines on their 737 and A320 families. The new engines they've put in are around 14 to 15% more efficient compared to the older ones. However, the new CFM Rise engine is expected to surpass this improvement by a significant margin.

There’s a reason these jets were never used…noise. In the 80s theses engines tested on the outer limits of stage 3 noise levels and today we are at stage 5 which is something like nearly 20 dB lower. Also, counter rotating props are a horrible idea for maintenance and longevity-too many moving parts in opposite directions and hence only the Russians employ that technique today. Plus, moving your blade to the outside on the endings where you cannot contain them in the advent of a failure or FOD hit, goes in counter to the last 30 years of standards and policy making for “contained blade separation”. Just ain’t gonna happen.

[@generaclesdey4622]

The wingtips of the propellors are a leaky airflow, wasting energy and fuel. The dual counter-rotating propellor-pairs are noisy because air is compressed and released. It's as if the engine is "clapping it hands" as propellor tips converge with each other. Ice buildup on the Props was also an issue!

[@martinandersson5278]

I wonder why they didn’t hire you😂

[@generaclesdey4622]

[@dextermorgan1]

​@@generaclesdey4622That's sounds about right. You seem to know what you're talking about. Why would Boeing need someone like that?! 😂

[@generaclesdey4622]

Those of us who seriously practice Risk Management spot the issues I listed immediately. RISK is not painful until it morphs into an ISSUE, so new technical ideas have to pass a rigerous scrutiniy to identify how known Risks can be shielded from the circumstances the will create the ISSUE. In this case, I believe that no such serious discussion has been presented.

[@bananajoe3669]

In Europe we introduced the A400M. At altitude of FL 300 this plane is very clearly to hear and much louder than regular airliners. I guess with that fans it will be the same.

If GE CEO really said "This NEW engine will destroy the entire aviation industry" then who does he think GE is going to sell this engine to?

[@dannybryant6873]

Back through the decades Popular Mechanics magazine kept predicting the return of the turbo prop. And jet engine companies kept making the front fan bigger and said "good enough"

[@porcelainthunder2213]

This has been around for 40 years. It pops up every 10 years or so. 0:03 They haven’t been put on planes yet. And they won’t be. They make far too much noise, they are slow, and the efficiency gains aren’t as good when you are running your engine longer because it takes more time to get there.

[@javadj184]

So basically they are inventing turboprop again.

[@jebise1126]

yeah its turbo prop all right. just to rename it to sound more fancy

[@scottpageusmc]

Yeah, I'm not buying this. - former Turbofan Test Engineer for Lockheed and Rolls-Royce at Stennis Space Center from 2007-2012 on the Trent 900, 1000, and XWB.

[@danbenson7587]

Vortexes peeling off the rotating blades make a noise, a lot of noise. I won’t hold my breath on this one. The open blades will be hard on tall baggage handlers.

[@petercrossley1069]

Vortices not “vortexes”.

[@DJ-gs8ly]

I've been with Boeing for 20 years now and I could tell you it's safe to say after we outsource cut some costs and use some super glue. These things won't work like they're intended to.

[@Rsantana380]

how is this going to work in extreme cold?

[@GAvation_Guy01]

I wonder how many planes with these types of engines with crash due to bad weather and maintenance and bird strikes😂👀👀

[@Chris_at_Home]

I was in a P- 3 squadron in the Navy and the props were one of the biggest maintenance items for the mechanics.

[@MarcosBay_]

If they equip the 737 I am sure many will fall

[@mikaelbiilmann6826]

3:36 Haha, A320 written on a Boeing 737. 😅

[@chaspfrank]

Wait till the first one throws a blade without a containment ring. Remember that C-130 that lost a prop blade a few years ago which effectively removed the cockpit from the rest of the fuselage? Or at the very least, it goes through the fuselage like the largest and fastest samurai sword you ever saw. No thanks.

[@JT-cf7dq]

That C-30 Crash was bad!

[@colinmacdonald5732]

Clickbait much?

[@ncooper8438]

How do they contain a blade failure when the prop blades are not shielded?

[@jebise1126]

so how will those vortex generation in tips be more silent now?

[@tonylam9548]

It is of the most importance the PR people think of a fancy name for the new engines. This new duct fan or high by pass turbo fan is just a glorified turbo prop , and the industry spent lots of time and money telling the public the jets are superior to props and props are a step backwards. They managed to hide the fact from the ignorant public the jets are still struggling with the "sound barrier" for 3/4 century. Jets nowadays are no faster than those in the 1960s. The avionics and manors at the coffin's corner improved a lot.

[@kpd3308]

Considering the noise problem, perhaps they could be used for transoceanic flights. But that's a helluva restriction.

[@saumyacow4435]

So what happens when one of these blades separates and slices through the fuselage?

[@1chish]

So why not build a large turbine contra rotating turboprop for the A320 / 737 sized aircraft? Possibly with an over fuselage wing. Go on Rolls Royce Allison you can do this

[@eduardodaquiljr9637]

By installing more fan blades there's no need to increase fan diameter if getting more thrust.You can increase rpm also but not so much because of vibration.

[@andrewtaylor940]

Every few years they pull this one out again and proclaim it the hot new thing. Until the public or executives find out just how much noise it makes. Look up the XF-84 “Thunderscreech” for an example of how far back this goes. And just how bad it can be. That one physically disabled the ground crew out to 100 yards.

[@cyrilmeynier8868]

The engines on the antonov-70 looks a lot like that, but they are classified as turboprops. Makes me wonder if there is still a clear distinction

[@ADobbin1]

Its called a contra-rotating turbo prop.

[@stephenallen4374]

What happens when there's a bird strike those blaze will snapped off and hit the aircraft fuselage😮 they haven't thought of that

[@unclefart5527]

I remember them hanging such on a DC-9. And that was supposed to change the world (according to Aviation Week). LOL.

[@Ryarios]

Jet engines have to pass a contained failure of the turbine blade test. How will they treat this type of engine? Will the consider these blades propellers or turbines?

[@JohnQDoe-ut3jj]

This video has so many aircraft identification errors it’s almost comical. Apparently the creator doesn’t have a firm grasp on the differences between the 727 and 737. Clearly the script is being generated by a computer voice but for crying out loud, double check your information for accuracy before you upload it to KZbin

[@rickwhite4137]

Why isn't there a funnel in front of the engines to force more air in?

[@jameswaters3939]

Right ... Some kind of housing or nacelle for the front to better channel relative wind? Kinda curious also about this? Plus, I think it would 'look' better to the flying public.

[@MykePagan]

Shouldn’t these be classified as “Turboprops”

[@stephenwood9703]

So basically super propellor engines ?

[@rockmandokeeperofthestones70]

No. Because new generation aircraft have low and forward hung engines due to lack of wing ground clearance and are not suitable for retrefittung due that sales will be shite untill overhead wing design returns to accomadate jet turbo prop engines which are not new in concept or functional use as yet not in a wing mounted slung pod design. Plenty of turbo props about as turbine powered propeller powered aircraft exist already.,

[@timkis64]

its an old design that was never adopted decades ago.& will never be adopted now either.

[@garethdavies2538]

"Destroy the entire aviation industry." Get real!

[@MrDiamondFlyer]

So ... Boeing will not develop a new model for now because they wait for this exact technological breakthrough to incorporate it on their next model. Meanwhile, this engine is planned to be tested on an Airbus 380 ... it's a bit hard to imagine how this engine will destroy the entire aviation industry by catching the two market leaders by surprise ;-)

[@Pete68T]

This Wont be better than TurboFan as the Thrust is Not Contained So a Lot is Wasted .

Then they unbalance the aircraft and it bites the dust, thanks Boeing

[@TheSanych]

So, It seems, that aircraft industry will just lobby more loose regulation for engine noise and we'll go back to open fan engines. And it will be sold to the public as great innovation. Welcome back to the 50''s of XX century 🤣

[@casey3831]

So this is really basically just a turboprop for all intents and purposes right? Or am I missing something lol? As an airline pilot I hope these engines don’t actually become the norm. Why? Because I think they look stupid

[@tomg6284]

The noise will kill this BS jet engine. To darn loud.

[@tsclly2377]

This only makes sense on airfreighters.. These engines are only more efficient at slower speeds, lower altitudes and people don't want to see those blades, as they represent a real visual threat (real or not), so they need to target the retrofit market. Airfreight also is not as severely constrained by time slot performance (thus can avoid weather conditions that may be a constraint) or have the huger passenger liabilities. Passenger traffic is very fickle to economic conditions and there is a great concern of this turning negative in the near future, while airfreight is less elastic. I'm laughing at the hydrogen 'wokeness'.. it will never happen in large aircraft, perhaps a few 'woke' propeller small trainers (that only have to be able to fly for two hours at the most) due to cost, ground facilities and weight.
