Roman Bühler also makes these…with more blades.
I just want to inform you if interested that I have solved the problem of the actuators and also tested a two bladed prototype of this 50%+ efficient type machine.

1978 McDonnell Aircraft reached 51% efficiency with another H-darreius…called Giromill.
How about 40 TX trainers and 40 Gripens….only 2.1 billion ??
Thanks for sharing Jason !
Here is another remarkable video of the same replica racer; https://www.youtube.com/watch?time_continue=1&v=ORCv6UayRns
The building video.
Here is my try on the subject…lifting fuselage.
There is a small free flying model of it.
Along the same lines…sort of…
The Boeing blended wing concept.
https://en.m.wikipedia.org/wiki/Blended_wing_bodyIt’s so radical it would likely have to have a full scale proof of concept before (rightfully) conservative airlines would order them.
Frankly, I’d like to see the USAF order some as advanced tankers to supplement the KC-46, that would certainly demonstrate the concept.
You have be to real careful now.
There is a flying wing, lifting body, blended wing…and a lifting fuselage…latter is the Burnelli /DeMonge concept from 1922.
Fairly similar Dave – it is just as ugly 😀
Yes..they are hidiously ugly…but could they be developed to something new and exciting ?
Awesome data ! Great photos.
Thank you.
Just think about putting Scaled Composites to revitalize the concept ?!
Easy Jet electric passenger plane with V-tail.
Eye witness has seen something; https://abc7.com/historic-small-plane-crashes-at-state-prison-in-norco/5264698/
Scaled Composites has a new V-tail design ..also a stealth…type 401.

A real tragedy.
It will be interesting to learn the cause(s).
It had been flying since 1993.
https://m.youtube.com/watch?v=4H8lF_RZ8FIMy heartfelt condolences to the pilots family and friends. I’ve met a few of the PoF staff and pilots, very, very nice people.
Yes it will be interesting.
Any guesses ?
R.I.P. David Vopat !
I’m pretty sure they can help you with that information here; https://www.beechcraftheritagemuseum.org/
Ok . Test pilot died when v-tail separated the aircraft. http://kuknamys.cz/1_48/0262.htm

I get the impression they never really solved the problem of the weak tail assembly.

Bill Odom made a record with it; https://www.youtube.com/watch?v=5XpRptVPrtI
Yes it is, for all types.
Since it doesn’t happen with warbirds these days, many forum members may not appreciate the continued flight in IMC, leading to loss of control which leads to in-flight breakups.
If happens to higher performance, owner-flown types because they are out there in the bad weather whereas lesser types are still on the ground. If the pilot is a bit rusty with his/her instrument work, bad things can happen. Unfortunately, many who own high performance IFR capable aircraft are busy professionals…which is how they can afford the aircraft in the first place…and despite training requirements put in place by the FAA
and their insurance companies…get into trouble.Yes, Beech won the trial and also the FAA conducted a special review of its type approval and found it safe.
Is the Type Approval open source info ?
