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.

A bit of pre-X-wIng work with a similar config.

Hi,

here is two X-wing concepts,first x-wing single rotor helicopter

and the second is X-wing tandem rotor helicopter.

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.
