A nice Sikorsky design, which strangely enough uses rearward-facing pusher propellers instead of turbine engines.
A much better quality picture of this artwork and adjoining three-view plan. These were published in the September-October 2003 issue of Scott Lowther's Aerospace Projects Review.
Thanks for those, Stephane!
Another from Aviation Week, or one of those mags...
We have here the latest in primitive technology.
Internet + Opinions = OMG we are SCREWED!
Yippie Kai Yay, Mr. Falcon.
A bit of pre-X-wIng work with a similar config.
X-Wing never would have been practical, it was way too much complexity and cost for marginal return. Just consider what would have been involved with transtion to and from rotorborne/stopped rotor flight alone and you'll see what I mean.
Oh yeah X-Wings also have the gliding/autorotation charateristics of a brick.
