US troops discovered a Messerschmitt P.1011 prototype on 29 April 1945. It was 80% completed. Bell borrowed it in 1948 and decided to fly it with a J35 engine but the aircraft was too damaged. Then, the Bell team decided to produce a design based on it and show their proposal to the Air Force in late 1948 but the Engineering Division stated that it was unable to carry enough fuel and armament to be a good interceptor. Bell proposed building two experimental aircraft to prove the validity of the concept, that was the Bell Model 60 / NACA X-5. Several fighter projects were studied from 1949 to 1951. A single 5,200 lb J35-A-17 would have been the powerplant (720 mph at sea level). Armament: 46 rockets and nose mounted AN/APS-19A radar.

Hi Maveric,

unfortunately, the answer is no. All drawings were included for pure ornamental purpose to illustrate an article about the Bell XV-15.

BELL *All Wing* helicopter project dated 1954!

From: http://www.flightglobal.com/pdfarchive/view/1954/1954%20-%201943.html?search=Bell

The text mentioned: "The prototype is now being built"  ???

It seems related with the D-218 cargo helicopter project.

Hmmm, I just came across this one and the linked posts, what an interesting design.  I wonder if the lifting fuselage would provide enough lift in forward flight to offload the rotors?  It probably wouldn't increase speed very much (look how thick the wing is) but it might increase efficiency at modest speed.

The "wingspan" would be problematic for maneuvering, but it's also not hard to imagine it as a very effective assault transport.  Big clamshell doors open forward and 50 troopers run out or maybe four light vehicles with four troops each drive out, simultaneously, and the transport is away again in seconds.

Does anyone know of any other "flying wing" or "lifting body" helicopter designs?

Barrington Bond,

That looks a lot like Bell'S Hypersonic Transport design...

Hi,

What was that Bell aircraft ?.

http://www.google.com/patents?id=jRF0AAAAEBAJ&printsec=abstract&zoom=4&dq=hawker+aircraft+airplane&num=100

I suspect this to be depicting the Bell D-400A as seen in this diagram published in page 2:
