Hi,

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.
http://www.secretprojects.co.uk/forum/index.php/topic,1222.msg24342/highlight,bell+d-218.html#msg24342

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?

And here is a twin-boom fighter, thanks!

Barrington Bond,

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

Hi,

What was that Bell aircraft ?.

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

Not sure if these have been posted before.
From "The Bell Helicopter Textron Story", David Brown:

Hi,

I heard that the Bell X-5 was redesigned as interceptor
aircraft,is that right ?.

And may be the answer to my question,from my dear Scott site;

XP67_Moonbat · 11 October 2012

Anybody have information on the RX-1 recon variant of the X-1?

hesham · 29 October 2012

By the way,

that aircraft was in the report D-7605,with all projects here;

That is the source,

and the report was D-7605.

Hi,

here is the Bell D-7233 project for the C-119 transport aircraft fitted with air cushion
to landing,also in this topic,I spoke about the Bell D-7605 for the air cushion which used
in various aircraft.

Hi,

here is the Bell XV-3 two shapes,one is early configuration with 3-balded proprotor,
and the second is the final configuarion with 2-balded proprotor,note also the other
different between them.

hesham · 14 November 2013

Hi,

also from Germany museum site,here is a Bell VTOL design of 1970s,it looks
like anther Bell VTOL aircraft from my dear Scott's site;

And here is again the Bell VTOL aircraft series,as my Dear Scott sent a looks like
that list,with addition the Bell D-133 profile,and also developed from X-5.

Stargazer · 25 November 2014

Nice find, the D-133. I had it listed as a fixed-wing version of the X-5 but hadn't seen a picture before.

Hi,

here is the Bell LMA,a Large Multimissiom Amphibian with air-cushion to land,and
a comparison with Boeing 759-182A.

royabulgaf · 22 December 2014

I think International Rescue was interested in this project.

hesham · 10 May 2015

Hi,

here is a two versions of Bell-222,i think they remained a projects,the Gunship and
the missiles carrier;

Nice findings hesham,this is the first time i see the model 222 as a gunship.

best regards

specify who knows the project Bell Helicopter Model d261 was a single or double, and where mozhnonayti more information about this project.

(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).

No worries, I do exactly the same!!! ;-)

interesting model where you can still see the images D-261

hesham · 11 October 2015

Nice find Mil.

mil · 14 October 2015

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.

Orionblamblam · 15 October 2015

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

Hi,

the Bell ETA (ejector thrust augmentation).

sienar · 29 April 2016

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 short blurb and artwork from the June 1956 issue of Flying magazine about the Bell D-216.

Enjoy the Day! Mark

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

Amazing find my dear Mark,

and as I discovered in this NASA report,some Bell Projects with air cushion,the attack
aircraft called Off-Runway Tactical Fighter.

Mark Nankivil · 9 February 2017

Good Day All -

In splendid color, Bell's LMA proposal....

Enjoy the Day! Mark

Apophenia · 9 February 2017

Thanks ... great stuff Mark! Interesting to see Bell working their Air Cushion Landing System concept

cluttonfred · 10 February 2017

Great stuff, thanks for sharing. Does anyone know if these retractable air cushion designs were actual projects or just speculative artwork?

yasotay · 10 February 2017

If I am not mistaken Bell did test the air cushion concept on a seconded DHC-7 from the Army in the early 70's.
