> JetZero, co-founded in 2020 by start-up veteran Tom O’Leary and aerospace legend Mark Page, is developing the world’s first commercial all-wing airplane. With up to 50% better fuel efficiency and lower carbon emissions compared to existing commercial airliners, JetZero's Z4 will offer the aviation industry a clear path to achieving its 2050 net-zero goals while also elevating the passenger experience. Working alongside the US Air Force, NASA, and the FAA, and backed by decades of investment and research into blended wing technology. JetZero looks to enter commercial service in the early 2030s.
Where an "all-wing" airplane is, kudos to Gemini,
> one that merges the main body and wings into a single lifting surface. This can reduce drag, lower fuel burn, and expand interior space.
This sounds fixable in avionics and training. (Shallow, gradual banks.)
Note, too, that a larger lifting body needs to bank less to execute the same turn as a craft with more loading.
This is not really helpful for passenger comfort. For a turn to be comfortable, you want the turn to be such that the effective force the passengers feel has no sideways (relative to the passengers) component, and the required roll angle is only a function of the velocity and turning radius. The aircraft design is irrelevant.
The Wikipedia article is mediocre: https://en.wikipedia.org/wiki/Coordinated_flight
Picking out my house, seeing tiny cars on a remote highway, etc. Even 100+ MP cameras and high resolution screens won't come close to that level of detail.
Where that number comes from: they claim 50% reduction in fuel consumption, which sounds doubtful to me, and fuel is about a third of flight costs, and I’m making some generous assumptions around perfect competition.
And that's before we talk about night flights when there's nothing to see, flights over water when there's nothing to see and so on.
So yes, I'm sure some people like windows. But the majority have demonstrated that they're just fine flying without them.
Edit: apparently 12.5% of the population has claustrophobia. If 5% of flyers choose a different airline due to simulated windows that would wipe out any cost benefit from fuel savings.
Ah... A dream
Just hope they don’t make an “ad-free” window a premium upgrade…
Suffice it to say, from stable aeronautics at-edge, jet way footprint efficiency, ground support efficiency, airframe pressurization, cargo & passenger logistics, lifespan, and certification, there are many, many reasons “tube + wings” is the dominant airframe architecture for all non-military aircraft.
traditional looking commercial jets, their designs, their manufacturing processes, their innovations (yes boeing/airbus do innovate and have for a long time even though it doesnt seem that way) have all been shaped heavily by human blood. to some degree a radical new design almost guarantees more deaths at a commercial level there's really no shortcutting this without it.
dont get me wrong im super open to the possibility that something like this is possible itd be better for the whole world, but there's no way we get there without re-experiencing some hard lessons if we want to push it pash some sort of proverbial finish line
This assumes the lessons were specific to the body type and aren’t generalizable?
Novel things always look unviable. First cars, first planes, first EVs all looked like dubious gimmicks sorely lacking the required infrastructure.
Scaled Composites? Now that’s a name I’ve not heard in a long time…
Presumably we haven't heard as much after Northrop bought them?
I think it's awesome that Scaled Composites is involved... they really have such specialized knowledge of all kinds of aeronautical engineering.
Btw, it will take hydrogen propulsion for their planes to be zero CO2 emission.
Why does it need bold new design and innovation? More people (can afford to) fly every year, more safely, and with broadly more consistency than they ever have. The success of the commercial aviation industry as a whole is breathtaking.
From a regulatory perspective, the layers of bureaucracy needed to get approval to build a bridge has nothing on starting up an airline manufacturing company. Once you have a company with a history of approval, you can practically do what you want, but getting to that point is nearly impossible.
I also feel like a lot of modern air travel is designed around making something that's highly unnatural and inherently terrifying into something palatable for most people. I'm not talking about actual safety, but the perception of safety. Which isn't exactly a logic thing. More about keeping that lizard brain from freaking out too hard.
