(I'm sorry but why did you leave Russian in your English? The word "mozhnonayti" means "can be found"!)

The D261 was a 1964 two-seater attack helicopter proposal for the AAFSS contest (which was won by the AH-56 Cheyenne).

Bell Model D-261 Double combat helicopter project, it is not clear how you can sit in the front cabin, it is very small for the pilot.

Guy in front would have been the gunner... and from the looks of it, he must've been prone.

And so the endless circle of life comes to an end, meaningless and grim. Why did they live, and why did they die? No reason. Two hundred million years of evolution snuffed out, for in the end Nature is horrific and teaches us nothing

Pretty interesting summary of the X-5 program here; http://documents.theblackvault.com/documents/aviation/XPlanes/BellX5.pdf

Some of the more notable bits;

Bell was very serious about putting the XJ-46 in the plane, and also looked at adding booster rockets to the X-5. First twin 1500lbs, and by July 51 rockets with 4000lbs of thrust were looked at, with a projected speed of m1.4 at 40000ft. The Sapphire was also looked at. There is also a mention that douglas was interested in similar rocket boosters for the x-3.

Early in 48 Bell began looking at VG aircraft. In August of that year they were loaned the P1101. Bell proposed building 24 interceptor airplanes of their VG design, and for a time the Air Force was interested until the AMC killed the idea. They then proposed two research vg planes be built.

Prior to the X-5 program Woods designed a low-level, twin engine, swing wing attack plane. This design did not have the wings shift for and aft but instead used fuel transfer to shift the cg as the sweep changed.

Woods envisioned the X-5 tactical derivative as having an intake screen that doubled as a radar antenna and the dive brakes could be used as mounting points for rato.

General Saville visited Bell in July 50 and asked Bell for projected data of a fighter X-5 with different engines, but Wright Field was skeptical and shot the idea down.

In July 51, the issue of creating an X-5 fighter derivative was brought up again. This time Colonel Victor R. Haugen saw the X-5 as being roughly in line with fighter studies then under way and asked the Weapons Systems Division for an analysis. There summary was that a virtually complete redesign would be needed to turn it into a fighter.

Good Day All -

A recent EPay buy of a set of slides yielded quite a few pieces of Bell Aerospace concept artwork.  Attached are the first ones I have cleaned up.

Enjoy the Day!  Mark
