Hesham also mentioned a D-209 for the Cobra attack helicopter, instead of "Model-209".



"Model D209", as his source refers it to, is likely just a simple designation mistake.


Or... perhaps the D-209 became the Model 209 when it went from proposal to actual prototype... although this doesn't seem to be standard Bell practice.

That was my second thought, but its not mentioned with that designation anywhere else because, as you said, it doesn't seem to be standard Bell practice.

D-196 is not in the list (it was a D-190 development).

Hi,

also here is the Bell Model-210;

the Model-211 Huey Tug and the Model-249 AH-1S Super Cobra ( fitted
with shortened version of four-blade main rotor from Model-412) were
well known helicopters.

For the Model-215,Model-216 and Model-217G,please see;

Certainly NOT so! Just try and find photos of the Model 211 and you'll see what I mean. Now if you DO have pics of it I'd be more than interested... I've only got one myself, see below.

I think he made it up to look helpful.

Despite the gap in the system I can't find a thing on his "D-2040". :P

I think he's talking about the D-2240. (aka: Model 2240, or just Bell 2240)

There was no such thing as an "XV-22". The first 6 Ospreys (FSD prototypes) were designated YV-22A. The prototype Eagle Eye was designated TR911X; the TR916 is the US Coast Guard version (HV-916 being the USCG designation); the TR918 is the final version.

The Bell Model 417

Bell Helicopter launched the Model 417 light turbine single at this weeks Heli-Expo show in Dallas, Texas. The 417 is a hot-and-high derivative of Bells Model 407 light commercial helicopter [see attachments], with a new co.ckpit, rotor system and the more powerful Honeywell HTS900 turboshaft.

A prototype modified by Bells XworX research centre from a used 407 will fly in April, says 417 programme executive director John Ricciardelli. Certification and first deliveries are set for early 2008, with the 417 to be produced alongside the 407 at Bells Mirabel plant near Montreal, Canada.

The 417 is intended to compete head-on with Eurocopters AS350B3, which is becoming increasingly popular, particularly in Europe, according to Honeywells latest civil turbine helicopter market outlook . The 417 is priced at $2.11 million in 2008 dollars, about $300,000 more than the 407.

As well as replacing the 407s 813shp (605kW) Rolls-Royce 250 with the 970shp HTS900, the 417 has a new all-composite main rotor derived from that on the Model 430 intermediate twin, a beefed-up tailboom and more powerful tailrotor from the Model 427 light twin. Gross weight is increased to 2,495kg from the 407s 2,270kg. The 417 has a Chelton electronic flight instrument system with two 150 x 200mm (6 x 8in) liquid-crystal displays as standard. The same co.ckpit is available as an option on the 407. The new avionics and engine will reduce operating costs, says Ricciardelli.

Compared with the AS350B3, the 417 has a higher gross weight, competitive hot-and-high useful load and superior hover out of ground-effect, says Ricciardelli, adding: The market is expanding. There is room for both the 407 and the 417.

The 417 was formerly the 407X and is the basis of Bells RAH-70 Armed Reconnaissance Helicopter (ARH) for the US Army, the first of which will fly just a week or so after the 417 prototype. The 417 will do the airframe/engine integration work before the ARH flies, Ricciardelli says.

Also here...

http://en.wikipedia.org/wiki/Bell_407

 

The Bell 417 was a growth variant of the Bell 407, in essence a civil version of the Bell ARH-70. The 417 made its first flight on June 8, 2006. The 417 was to be powered by a Honeywell HTS900 turboshaft engine, producing 970 shp (720 kW) and includes full FADEC controls. The cabin will seat 5 passengers in club-seating configuration, in addition to the crew of two. The civilian 417 was canceled at Heli-Expo 2007 in Orlando.

It seems you guys getting confused between Models 407, 417 and 445, and the Wikipedia quote that hesham posted is ambiguous and doesn't really help... So, if I'm not mistaken:

  • The Model 407 was a proposed commercial helicopter looking basically like a modernized Jet Ranger The proof-of-concept demonstrator [N2770X, later N407LR] was a Model 206L-4 LongRanger. The yellow demonstrator in hesham's post is a Model 407.
  • The ARH demonstrator, seen in Triton's pics, has also been described as a Model 407 [N91796].The Model 417 was to be a growth variant of the Bell 407, sometimes described as a civilian version of the ARH (which in itself is not clear since the ARH was supposed to be a military 407!). It first flew in June 2006 and was cancelled in 2007.
  • The Model 445 was the ARH-70A Arapaho, the all-military version for the Army that was cancelled after four prototypes were built [N44515, N44548, N445AR and N445HR].

Wikipedia is wrong, as they give the production ARH (H-70) as another Model 407 while in fact it was Model 445.

EDITED: found pics and data on the Model 417 (see below)

Found pics of the Model 417. Apparently the story is more complicated than I thought. The ones that have "Bell 417" written on it show it on display at exhibitions or on the tarmac (not a sign that it actually flew), but two distinct helos are seen actually flying here, one registered N415AT another one registered N417TX. The registrations (always chosen with care where Bell is concerned) leave little doubt that at least the second one was a proper Model 417 prototype...

The Bell Model 217G was not helicopter,

it is as I think a gearbox or something else,here is an info
about it through Model 208;

the Model 208 was basically a UH-1D re-engined with a Cont.
XT67-T-1 free-turbine power plant,comprising two T73-T-2
Model 217 turboshafts couple to a common reduction gearbox
and output shaft.

What upgrade of the 407 is this? I'm hoping its an artist's impression for a valid proposal.

Anthony, you're in luck. This is a proposal by Northrop Grumman to modify the 407 with the control system of the MQ-8B Fire Scout.

My dear Lark spoke about the Bell D-76 here;

....Bell Aircraft , on it's way to becoming a premier helicopter manufacturer
performed -Tiltrotor- design studies as early as the 1940's.One of their
earliest concepts was the Model 50 Convert-O-plane followed by the D-76 'rotor plane' for a single occupant....

Here is a beautiful drawing of the Bell D-292 ACAP contender (the prototype of which was evaluated by the U.S. Army against the Sikorsky S-75).
