XV-1 / XV-2 / XV-3 competition

devi · 25 August 2006

Friends.

know, that in competition participated seventeen firms: 19 proposals.

1) McDonnell Model M-82--------------XV-1
2) Sikorsky Model S-57------------------XV-2
3) Bell Model B-200----------------------XV-3
4) Lockheed TDN Model L-203

Help to find and other projects...

boxkite · 25 August 2006

Btw, David Brown gave the designation D200 to the Bell XV-3 in his"The Bell Helicopter Textron Story" instead of B-200. This should be correct.

devi · 2 September 2006

Hi boxkite.

I think, that should be: Model 200(B-200),
Because, development of model D-188/XF-109, in 1955-1956 years,
and development of Model 200, in 1950-1951 years.
(development of Model D-200 more late, than Model D-188)

Model 200-------------XV-3
Model D-188A--------XF-109
Model D-200--------what scheme or what type of the helicopter or airctraft or ?

Hi,

Was that Piasecki SUP project belong to that competition ?.

Pioneer · 27 March 2007

I am sure that Martin also entered a design to this competition

Pioneer

That could be the MArtin 365 model, but I have no other information.

Hi Jos,

Do you know that Gyrodyne project involved in this competition ?.

hesham · 10 July 2007

Hi,

The Kellett K-25 was a project of convertiplane powered by two
Lycoming XT53-L-1 gas turbine engines,it was involved in this
competition.

source for drawing only; Flightglobal.

Jos Heyman · 10 July 2007

Is it Kellett K-25 (your message) or Kellet K-15 (the pic file name)?

hesham · 11 July 2007

Hi Jos,

Sorry I correct it.

hesham · 29 August 2007

Hi,

May be the that Vertol convertiplane project was the
proposal for this competition,please see;

Jos Heyman · 29 August 2007

Considering that the XV-1, XV-2 and XV-3 appeared in the 1953/54 period (based on their serials), I would not consider a patent dated 1960 as part of that competition. Perhaps this patent is an outgrwoth of the Vertol VZ-2.

joncarrfarrelly · 29 August 2007

The patent file date is Dec. 28, 1956.

Hello All!

The competitor from firm Gyrodyne: Model GCA-5 (or Model GCA-15, as it is written in a picture.Picture on top)

luedo34 · 13 June 2009

Hi, where there any other tiltrotor-contenders in this competition, apart from the built XV-3 and the (unbuilt) Kellet K-25?

hesham · 13 June 2009

Hi,

for Kellett K-25,it was displayed here;

http://www.flightglobal.com/pdfarchive/view/1958/1958%20-%200381.html

And for the Gyrodyne I think it was GCA-32 project.

luedo34 · 14 June 2009

Thanks for the link, intersting stuff.

hesham · 14 June 2009

Thank you Luedo 34,

and I check from GCA-33,it had only two seat and one engine,and the GCA-32
was a convertiplane,but it powered by two engines and had seven seat,also
its rotor diameter 60ft,and for GCA-33 28ft.So I think it's anther project
for this competition,may be GCA-31.
The Goodyear Convo,I think it involved too.

lark · 14 June 2009

The convertiplane below in the illustration seems to be
an early design sketch of the McDonell XV-1..
Which is the multiwing aircraft ?

lark · 14 June 2009

Error..
The convertiplane is the Bell design ofcourse..
I'm getting older.. ;D

I think the Vertol VTOL aircraft which was mentioned in this patent,discribe
in this Flightglobal page;

http://www.flightglobal.com/pdfarchive/view/1956/1956%20-%201573.html

Jos Heyman · 14 January 2010

I think we discussed this Vertol design earlier in this set of postings. Timing is wtrong.

hesham · 21 October 2010

I suggest that,

the Convertiplane for Prof.Rutowski from the Wayne University
was involved in this competition,because the tender began in
1951.

Jos Heyman · 31 March 2011

In June 1952 Bell presented a mock-up of the Bell 200, what later became the XV-3.
Would anybody have a photo of that mock-up?

hesham · 4 September 2011

Hi,

and may be,it was the Goodyear proposal;

Essentially a cousin to the XFV-1, a VTOL liason aircraft.

Thank you, Paul.

It's Beech design.

The design you're showing, hesham, is the Beechcraft Cascade.
We've got a whole topic on it:

Oh sorry my dear Skyblazer,

we can transfer it to this topic.

Hi,

hesham · 14 April 2021

Hi,

I think Mr. Frank A. Dobson who designed a VTOL device in this topic,
he involved by this concept,need confirm ?.

Not sure if this goes here: McDonnell XV-1, blueprints are up on Ebay (not sure who's interested, I for one am not bidding. And for clarification, I'm not the seller either):

Also we can say,

1- McDonnell Model M-82--------------XV-1
2- Sikorsky Model S-57------------------XV-2
3- Bell Model B-200----------------------XV-3
4- Lockheed TDN Model L-203

I think that,the Dobson is wrong,and from a reliable source,the contenders
were 19 from 17 companies,and we forget Richard Prewitt,to be;

1- McDonnell Model M-82--------------XV-1
2- Sikorsky Model S-57------------------XV-2
3- Bell Model B-200----------------------XV-3

Platt-LePage Aircraft · 3 February 2024

Rheem was the Platt-LePage PL-15 design.
Haviland Platt had ties to Rheem that continued beyond the closing of Platt-LePage Aircraft.
