Oh something new!!
Hello All,
Found this while searching the web, not sure if its of any interest but thought i would post it anyway. Cheers
VTOL Dynamics Ltd
Update 16/01/14: Ive spoken to them! gave them a skype call today. Its a form of hybrid-electric so NO cross-shafting. Twin gen-sets plus two other forms of safety which they wouldnt state. Anyhow, did a bit of a dig and there is a video on You Tube of their POC test flight so i will try and find it.
The engineer i spoke too said they are talking to investors to get a full size platform built this year!
Cheers

Looks like a clean sheet of paper was used, but then why give the main body a tail similar to an ordinary Copter entrapped in a frame, or is that space for the open cargo/people pod area,
Whats the drive , same direction or Contra prop, where is the power unit, how does the Pwr Unit transmit the horses, through shaft and U/J's, or are they power cells at each corner, what happens if one set of props are shot off or fail to work, , the action of raising collective would need to be a work or art in contril wires or rods
Finally Eurocopter would contest the design of the skids, it seems they claim that sort of shape as theirs...!
But a very interesting concept, it would cost Mega Millions to make it to market, thankyou for posting most interesting.

Lets see what the real critics say!!

additionally i see an airplane that is more user friendly and less dangerous for ground crews (no tail rotor).

Not sure, according
Not so sure, according to this image, but I guess as with all concepts, its just a concept…
At least they took the time to build a 1/4 scale POC according to the site. Anyhow, just thought it may be interesting to someone.

From the picture of a stationary model each of the 4 stations appears to have 2 props, contra-rotating, making 8 props in total
In the rendered images the props overlap the covered wing section which seems to me to be a little wasteful of lift potential in the hover.

Not sure but if it acts like an Octo then it can fly with one or two motors out i think, I have a model that does it so i guess the principles are the same. All i know is the guy said two gensets and its a series hybrid so that means a battery pack as well i guess! I have no idea, sorry

IMO, that's a pretty basic good design, that still has a long way to go. Firstly, the addition of fenestrons to the ends of the covered wing sections would be a no-brainer to me - however, I'm not a helicopter designer!
Fenestrons would improve safety levels with regard to personnel immediately, and possibly improve lift performance with some dedicated attention to design.

Looks like it would be lots of fun to fly, and there does not seem to be any fundamental reason the design could not be made to work. The basic configuration was flight tested in 1963 on the Curtiss-Wright X-19. Unfortunately, I can't see any market demand for a single seat tilt-rotor with limited payload/range/speed/altitude capability and a price tag likely in excess of $1M.
For extra range you can pack your butt full of D cell batterys
