I still think the RSRA program should be a separate topic, which could then be linked to this one in hyperlinks...

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.

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.
