another one which is often evoked but nothing seems to have come out regarding pictures, dimensions etc... (speed , ceiling, etc... must be zero , even double zero "licence to kill its pilot")

"bird 6" is a model of Quetzalcoalus:

http://en.wikipedia.org/wiki/Quetzalcoatlus

a pterodactyloid (flying reptile, no related to dinosaurs) from late Cretacious period (84 to 65 million years ago). It was built for a Science TV documentary.

(I also love Evolution's secretprojects ;D)

Cheers,
Antonio

The third pic reminds me of something called 'Winggrid', website is gone now but was a concept involving 'feather-like' winglets.

Really great, probably the most agile lighter-than-air vehicle ever built.
But heavier-than-air, man carrying ornithopters still seem notto be
around the corner.
But, would there be any advantage to other concepts ? ???

Re: the flying scale-model of 'Quetzalcoatlus Northropi', there's the following paper: A. N. Brooks, P. B. MacCready (et al), 'Development of a Wing-Flapping Flying Replica of the Largest Pterosaur', AIAA Paper 85 - 1446, 1985.
(And yes, I gather the beast is officially Q. 'Northropi' because of its resemblance to one of Jack N.'s fabulous flying-wings.)
Cheers,

What about the Bich-16 and Bich-18? :D

I head that the Quetz was a real pain to keep from blowing off the vehicle while it was being taken uprange (people had to ride on the outside of the truck to keep it on...

Although it does fly, and surprisingly well, but I wouldn't quite call it an "ornithopter" because this means "bird's wings", and obviously this one ought to be called "whale's flaps"...

To be still the most precise, the ray is a fish. Then we have a fish wing and going to a classical greek derivative it would be called "ichthyopter"

Thanks! You are absolutely right, it is not in the shape of a sea mammal but a fish, indeed.

To be quite accurate, it should be spelled "ichtyopter". Thanks again!

I suppose AeroVironment mid-80's Quetzalcoatlus Northropi research UAV would fit in here:​

Ahem... "Ornithopter" means "bird's wing." Insectopters do not quite belong in the same category, do they?

Have googled a bit and although you're right about the literal meaning of the word "Ornithopter", but the general
meaning seems to be a flying machine, which produces lift by flapping its wings. The word "Insectothopter"
seems to have been created originally for that artificial dragonfly, as most hits refer directly to it, but is used
sometimes for other very small (insect sized) flying machines. Maybe a differentiation between machines with
a single pair of wings like a bird and others with at least two pairs, like many insects would make sense, but it
seems not to be used that way.

I assume you are referring to a Pterodactylus-like wing. Etymology rears its head here, apologies in advance.
Pterodactylus is derived from pteron (wing) and dactylos (finger), literally wing-finger.
Pterothopter, with both "pter"'s deriving from pteron, means, therefore, wing-wing.
I would suggest dactylopter (finger-wing) instead for the Quetzalcoatlus Northropi research UAV. Or Butch.
</pedant_mode>
Thank you for reminding me of Butch.

Unknown ornithopter.
here is the source,but it is not working.

http://www.impdb.org/index.php?title=Category:Unidentified_Aircraft&from=The+Green+Berets

(Edit: Judging the search results, the original source could be the DVD box "A Century of Flight: 100 Years of Aviation")
