Default The Flying V.

This month,s copy of Airliner World ( UK magazine) has a very interesting article on this new airliner concept, the flying V. Partly sponsored by KLM and Delft University of Technology. (TU Delft)

Apparently they, the Dutch scientists/ engineers are testing the concept with a 45 pound, 10 feet wide flying model, probably with twin EDFs.

Does anyone have any more info on this model, propulsion, control system etc .?

The problem with these type of planes sitting people that far away from the CG on the roll axis will make them sick with any kind of turbulence or roll input.

it’s very efficient though. Boeing had a big flying turbine model similar in design several years ago.

The efficiency of the flying wings due to the lack of a fuselage and tail surfaces is just a myth, very well known among airspace engineers: the drag from the special airfoil and other parasity drags created by the auto stabilisation wing requirements are quite bigger than those from a well designed classic airframe.

It was well documented by scientific studies and comparatives between top performance classic gliders and flying wing gliders (mainly Horten ones) and the results and conclusions were clear and kep up today. Flying wings developed since then were from other requirements (reentry requirements for the Space Shuttle and stealth for the B-2 bomber), but never performance.

The academic reference book on th ematter is "Tailles Aircraft in Theory and Practice" by Karl Nicker and Michael Wohlfahrt and English translated by no other one than Eric M. Brown, the world famous Royal Navy test pilot.

Thank you for replies.

I am just curious about the model, as it is a forerunner of a potential jet transport with the same range/ payload performane as an A 350 but with 20 % lower fuel burn. It is a long term project.

I know the Hortens etc were not succesful but this shape is quite different and who knows what it might lead to.

I have no opinions on the aerodynamics, we did not study flying wings on my CFS course, the RAF did not operate any, Vulcans don't count!

I am sure the translation by Eric Brown was spot on, fluent in technical German, and a highly experienced test pilot, the best.

I met Eric on several occasions and once had a great discussion with him on the single engine handling of the ME 262 in comparison with the Meteor and Canberra. Glad I never flew a 262 with its safety speed of about 170 knots !

This project model is Jeti controlled with Electron retracts, EDF s not sure !

That said, I wish them every success.
