latest miracle aircraft

latest miracle aircraft

RE: latest miracle aircraft

You can buy a smaller one at Brookstone for about $300.

RE: latest miracle aircraft

Reminds me a lot of the Moller project.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

RE: latest miracle aircraft

It looks like a re-hash of something from the 1870's, cyclogiro maybe?

Google:

"Austrian research firm IAT21 has unveiled a radically new type of aircraft that could render the helicopter obsolete, D-Dalus."




 

RE: latest miracle aircraft

Looks neat, but I'm skeptical. All you really see is massive reposting and cross linking.

If it really made a splash at Le Bourget, it would be in avweek, where it doesn't show.

RE: latest miracle aircraft

How does it make no noise when it has rotating blades and a jet engine?

The fellow who wrote this press release, in all likelyhood, has never laid eyes (or ears) on the "aircraft".

RE: latest miracle aircraft

...or ever thought about it.. ha

RE: latest miracle aircraft

I believe the person writing this press release is a woman.

Gizmag has some better photos
 It is essentialy a feathering paddle wheel design.

'We had to find a friction-free bearing'

Really?  Would you like to buy my perpetual motion machine?

I find these bearings very interesting. Some would call them friction free, others would not.

This says nothing about my HUGE skepticism for this "noise-less" machine built with alien technology however.

RE: latest miracle aircraft

I should probably point out that those that think they are frictionless forget about eddie currents.

RE: latest miracle aircraft

this is based on the low pressure that builds up under a spinning disc, yes?  seems like a difficult way to create a force ... the disc needs to be light so it doesn't require much power to keep it running, but stiff so that it doesn't deflect; and i guess if you mount it on gimballs you'd be able to point the force in any direction ... but i'd've thought that the low pressure would be reacted by atmospheric pressure from both sides = no nett force ??

how did Cranfield get into this ? ... a big enough bag of money I suspect will turn anyone into a 'hore ??

"'We had to find a friction-free bearing'"

I would think this would be the REAL news in this dust-up.

Miracle flying bedsteads surface pretty often, "friction-Free" bearings, not so much.  

RE: latest miracle aircraft

I think you will find that this is a feathering paddle wheel design.
Think voith schneider propellor
The thing that is different about this design, to prior attempts, is that the sideplates ( Discs) are solid thereby trapping the tip vortices. allowing a very low aspect ratio wing. I think his comments about the "Frictionless bearing " refers to the hinge bearings for the " paddle blades"

RE: latest miracle aircraft

I wonder if you can do something equivelant to autorotate or glide in this thing.  I for one would like to have some means of safely landing an aircraft if the engine(s) crap out.
