KLM and Delft University to Create New Flying V Airplane with Passengers in Wings
This two-pronged innovative flight concept coined the ‘flying-V’ embraces an entirely different approach to aircraft design, and anticipates a future for sustainable long-distance flight. dutch airliner KLM will be contributing towards the research of the aerospace engineering team at delft university of technology (TU delft) to make this highly energy-efficient long-distance airplane a reality. its aerodynamic shape and reduced weight will allow it to use 20% less fuel than today’s most advanced aircraft — the airbus A350. furthermore, the spectacular, V-shaped design — which takes its name from the gibson guitar model — will accommodate the passenger cabin, the cargo hold and the fuel tanks within its wings. https://cimg2.ibsrv.net/gimg/pprune....6326c5cca1.jpg |
I wonder what's in this for KLM and why they would attach their name to it?
As a fantasy design, sure, why not. But the little design feature that the centre of lift is way behind the centre of gravity could be a bit of practical problem. |
Hmm . . . those white spots on the centre cabin roof - Tear along the dotted line?
So we sit next to the fuel? Oh, and better have a very advanced MCAS to stop the engine airflow from being too curly. "And whatever you do Hoskins, don't round out." |
Similar to the Airbus Flying donut patent:

You might get a nasty surprise when you calculate the drag of such a "thing".
I'd like to see the airflow over such a leading edge and study the vortices that it leaves behind. => Airflow going outboard spanwise! That's no airplane but some clown's wet dream. |
everytime you are in a car you sit next to the fuel better or on top of it Just what surface is giving the lift? Whatever it is, it'll have to counter the AND effect of the thrust. If I could get a job as consultant for the company, I'd write a report consisting of just one word: Daft. |

I notice that there is no aircraft manufacturer associated with this "sustainable design." Perhaps KLM is just looking for good PR by sponsoring student engineering projects at a local university. |
Just chopped a "V" from the back of the Boeing

I wonder how that leading edge is to be deiced. And, I suppose, like the first few cabin windows of the 747, every one of those cabin windows would have to be able to withstand a bird strike. Both surmountable, I suppose....
But, if there's fire outside on one side during the emergency evacuation, getting everyone out on the other side in 90 seconds could be a challenge, it looks like a long walk from the back of one side to the exit on the other side! |

Bottom line - KLM gets green PR and likely some tax write-off for the suport, the profs get to publish and not perish, and some students get class credit for the cool promotional CGI work.
Judging the design from the imagery (since we have zero facts about the actual intended engineering and aerodynamics), I would propose that this be viewed more as a lifting body fuselage concept, with blended stub wings outboard the engines for additional (and flexible, slatted/flapped, aileroned) lift. As in the Cranfield U./Boeing X-48 concept Megan shows us :ok: . Minus the "theater" seating, which is what put the customer kibosh on Cranfield's concept as an airliner, although it's still being developed for UAV, tanker or cargo use. https://en.wikipedia.org/wiki/Boeing_X-48 In which case the center of body lift may be much further forward than obvious, and the high engines and ND thrust may actually be a plus. (As well as protecting the engines from FOD). Not sure that leading edge icing would be as significant an issue as with a regular airfoil, either. Except on the stub wings. |

Pick a member at random from, say, the A350 design team and there's a good chance that he/she will have come up with something equally unconventional during their university days. That's what students do. It's how they learn.

What a load of old knockers, naysayers and cynics so far, pretty sad imho. its a student exercise in engineering and, strangely enough, some students are pretty bright. Why have windows at all on an aircraft when other visual means exist and are used daily. Structural integrity surely and reduced manufacturing costs? |

Probably made by the same guy that made the circular runway project ( same NLR bureau)
Why have windows at all on an aircraft when other visual means exist and are used daily. Out of a curiosity, can you transport legally pax in a cargo aircraft (one with no windows at all ) |

Think Easy also did another concept design about 7 or 7 years ago also. |
I think it is great that we have people and companies trying to look forward! Easyjet is trying to push the boundries on electrical flights and now KLM on this. Perfect!
The fact that we are still being sold old crappy 1950's tubes as "new" MAX aircraft is beyond me.... |
20% fuel save vs A350!
Now that is worth a shot!
I figure if we can have a leap of this magnitude long haul can eventually be acceptable with regards to the environment,so why not. DAR I think that if we get this one flying ice is not a big problem to solve. Having logged a few 1000 hrs in turboprops fighting ice, only the Beech 100 was ever a problem as it never got over FL200 on the average 180 nm trips we flew. The B200 and the Do 328TP just punched above it , and in the B 737 for 10 000 hrs plus I never had any issues. DAR , lets embrace the Young and the idea. And if You have 150 Billion laying around mail it to TU Delft, NL. The Futures so Bright we got to wear Shads! Rayban On Regards cpt B |
