Can't wait to see this at a air show one day
The blended wing body has been in research for decades but this gives me hope that somebody actually will build one. The concept for a long time had been that of super jumbo BWB airliners that can carry 1000+ people while having the same footprint as current widebodies though Bombardier here is thinking "what if we make it smaller? You know, something we can actually build, sell, and prove that it can work, like really work?"
These aircraft essentially are proven designs . What isn’t working yet is the tooling, manufacturing, commissioning and maintenance programs, which will take decades… the industry is always aiming 20 years away. But it will happen.
@@christianweller4288 Yeah it's about time somebody actually builds one and it's a smart move to make it into a business/private jet first
@@TheOz91 They already have….. see USAF for details.
@@christianweller4288 The Air Force has flying wing aircraft, not a blended wing body.
@@TheOz91 Similar enough.
What a beautiful looking machine. I have not seen innovation like this in the commercial aircraft industry in a long time.
BWB aircraft, even at this scale, have been in development for at least twenty years...just not by Bombardier.
Innovation in aircraft has been slowed to a glacial pace. Too much government.
@@nunyabidness3075 too much risk. Besides, a cylinder is the best shape to contain pressure. Blended Wing Bodies bring significant challenges to make a structure that is safe in a very demanding environment. Commercial aircraft undergo massive amounts of stress and massive cycles.
@@rickintexas1584 The engineering risks are, unfortunately, the least worry. Certification processes, along with liability, are the real culprits. First, anything new gets forced to put in triple triple redundancy. (That’s noncuple, or nine fold). For instance, a regular passenger plane might need redundant metal spar for redundancy. If lightning hits the plane, the skin will diffuse the energy and if a hole still punctures a spar, there’s still a second spar strong enough to do the job.
Now, Beech tried to certify their new design called the Starship. I don’t know the exact issues, but let’s call this historical fiction to make the point. They needed a redundant spar, but since the spars were composite, the FAA might have said they needed to make them much stronger because the composite might degrade AND still stronger because it’s non ferrous And stronger still because of the unknowns. Then, since the skin was composite, they’d need to embed a wire mesh for lightening protection. Besides the wing itself has to be stronger because it too is composite. So now the wing is much heavier, the spars have to be beefed up again. I really don’t know the real story, but I do know the difference between the prototype and production model was so much weight the planes were unsellable and Beech scrapped them. 25 years later, we of course know that the Beech engineers were right at the start. Composites don’t degrade that much when painted, and the spars would not degrade in a hundred years or mor not being exposed to sunlight.
Now, if you get through certification, eventually you have a crash. Let’s say the NTSB investigation concludes obvious pilot error. No problem? Nope. Not admissible in court. The lawyers will create a narrative based on who among the parties has money. So every parts manufacturer has to carry huge liability coverage and then the plane company has to have their own on top of that. Even winning against a fictional and fantastical narrative costs lots of money.
Remember the Boeing Sonic Cruiser? Back in 2001 it was pretty innovative. And look where it is now! :)
I like the shaping of it. Looks as though it might even handle a shorter runway than most other private jets.
Sounds like a good idea. Bizjet is a good size to experiment.
Looks spot on. Now go build it!
Look at 1:36 i do not think that is a render...
@@Paul-qk3wrCorrect. They have built a subscale model for testing.
It’s about time.
When is this coming to Microsoft Flight Simulator?
My first thought too
Getting close to the B-2 shape.. Maybe another 40 years...
Bernelli is back!
❤❤❤ Keep leading we love you👍👍
Love it! Pair it with a hydrogen-electric set up and Taylor Swift's MASSIVE carbon footprint could be a thing of the past!
Carbon footprint shmarbon footprint - it’s just moral mumbo jumbo from pompous elites assaulting my middle class wallet. 😂 But I love aviation tech for the sake of better flying planes.
I try not to give Taylor too much grief about it. As if she's been riding alone on the aircraft. I'm sure there's generally an entourage of friends and tour staff aboard.

One huge benefit of this twin top mounted Turbo Fan ENGINE is dramatically reduced Foreign Object damage prevention from FOD on the ramp and even in flight via Birds I really like this design of passenger jet and the known fuel efficiency gains and wider passenger seating arrangement etc. With modern avionics helping preventing stall recovery conditions I feel this design is ready for production and only the legal insurance cost factors prevent these newer Blended wing designs from making it to market in the USA. American government should help pave the way to ensuring these newer aircraft designs have the aviation safety regulation management to clear the path to commercial success.
Looks futuristic
They couldn't make the c series profitable without help, so I can't see this concept ever fly..
I think their biggest issues were multinational certification of a commercial airplane and marketing. Both of which Airbus is more equipped to handle. The technical side was a non-issue... This, however, is well within their business jet centric business model. So, as long as the newer composite construction techniques don't pose much more certification difficulties than the usual tube construction methods they have a good chance at success!
Not Bombardier's fault. It wasn't that the C-series was bad, it was that it was too good. Boeing meddled with the process, called in some favors from our elected officials that they had in their pockets. Embarrassing for Boeing and the US, IMO.
@@willdejong7763 Trump’s import duty didn’t help either!
Make it float too! Just in case...
Any numbers? How much more efficient is it?
A full blended wing can be up to 30% more efficient. This hybrid design retains a reduced empennage with both vertical and horizontal stabilizers - efficiency gains will surely be less than 15%. Which is still a lot!
The future of ALL aircrafts!
All aircraft MUST be electric the Tuesday after next Wednesday🤡
@@paulo7200 And they most likely will...or hydrogen powered, battery fans or fuel for jet engines.
I really hope Bombardier can bring this machine to life, the sad reality being that it takes billions of dollars of investment and that can only be provided by government in Canada. Taxpayers don't have a lot of patience for pouring billions into years-long projects without a guaranteed outcome, so this is a long-term battle. The A220 still isn't profitable despite being the best in its class, what would public opinion be if Canada was still funding this project on its own? I want our aviation industry to succeed independently, but the US and EU just have so much more capacity to subsidize their own industries.
I want to see a blended wing 4 seater kit aircraft?

🎶 My name is Bombardier Incorporated, but you can call me, "Bombardier." 😎✌️
Yes!
Sick
Does reducing power needed to propel the craft through the air, allowing smaller engines mean longer takeoffs (less powerful engines will accelerate the craft's mass more slowly from rest), or does this design also reduce takeoff speed? Perhaps in this market segment, there is already runway to spare?
Are the two models of jets shown at 1:25 calibrated in scale so as to carry the same number of passengers, or offer the same volume for cargo?
Asking, as the EcoJet appears to be ~70 percent the scale of the traditional Bombardier aircraft next to it. Showing cutaway, seat layout, or just general block area layout (cockpit, passenger, storage areas) would really help to provide context.
Boeing developed something similar a long time ago, never went anywhere, obviously. Hope this moves forward.
I would have thought that was a pretty bad 2-minute-video to sell an aircraft concept... starting with B&W images of some ancient history, remarkably little to enthuse us of the Ecojet, and the reminder that for what they've done today will be better in the next version.
Does anyone notice that the windows on this machine are shaped like squares?
Looks a bit like B-2? Or F-111?
With a shorty fuselage/body, emergency exits will be an issue for airliner concepts… might have to have doors that open through the floor to get down to the tarmac?
Also need to have a way out the top in case of gear up landings.
YESSSSS
What about the down sides of this design?
Ok but that seemed to be only a private jet design. Could they make it eventually for 100s of people like the boeing and airbus designs?
Little heavy on the buzz words... 🤣
You loved it. You chose to watch it. Buzz words stiffen a man.
❤
wish I could afford that
Ok…so absolutely nothing new and essentially clickbait.
Cool aircraft concept
Now, to get to why no one did it yet, are stability issues with that consideration resolved?
I even can't count it anymore how often the BWB-stuff popped up in the recent 30 years....and guess what?! Nothing will happen in the next 30 years as well
What ever it is. Most humans wont experience it. 😂
But we can enjoy watching it fly.
Sleek and innovative will always lose to "efficient enough designs", build costs, and market norms.
If I can get 10% off with free shipping, I'll buy two. Thanks.
When either one of the two engines explode, it will take out the entire tail structure...and possibly the other engine also....Paul

Please tell me it has ramjet/scramjet options. 😂
A person that spends $10M on a private jet is not interested in a 2% improvement in "eco-efficiency".
LOL ... nothing to do with birds and EVERYTHING to do with the research of Mark Drela at NASA

How much will Canadian taxpayers pay for this, only to see it sold to Airbus, like the C Series?
Since the nummber of super rich in next years will double or triple world needs new solutions. Planes have to be 50 % more efficient to level 2024 with 2030.
Me: Sexy!
Wife: Who?
This is bad advertising, the graphs don't have numbers or reference points. And the fact that only now bombardier has decided on the blended wing is not encouraging news. The blended wing has exsited scince WW2. The only blended wing to be mass prosuced is the b2 spirit, not the best private jet.
Graphs without numbers are a deliberate technique to avoid dealing with objective data.
The reasoning behind not doing BWB is the cost for R&D, new manufacturing techniques, and the time it takes to certify new styles of aircraft. With incentives to minimize drag and maximize efficiency companies are now looking to create BWB. The government is giving out money to those who develop a BWB. With extreme advancements in technology since WW2 a BWB is now easy to test and operate.
Blended wing wasn't invested in for a long time because the technology to cheaply manufacture smooth, blended parts didn't exist. Now days with composites, computers and highly precise machinery, we can easily produce these complex parts cheaply.
EMBRAER IS SO BETTER......
So another toy for the rich.... how nice!
yeah, well poor people don't buy airplanes to travel on global business a lot...so not much a market there.
barely blended wing more like
It's business jet, waiting for airliner instead. Since I might not be able to afford even a single flight in my entire life to fly it.
Bombardier tried the small airliner business, and it backed out. Don't expect another attempt any time soon.
The fact this is made by a actual aircraft company scares me
Why?
i get scared by change too. /s
Tbh, Ecojet is looking weird.😅 I like the design of Global Series more
Please make it have VTOL capabilities. It looks like the Starling VTOL jet already.
You’re dreaming. Requires far too much power, meaning fuel inefficiency.
Bombardier tried learjet 85 with all composites and it terribly failed. Aslo going back to Canadian history, avro aero was failed by the Canadian govt. So they will fail at this. I am not saying Canada doesn't have the talent infact they have the best talent but the system is not designed to commercialize very innovative projects.
