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.

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 ?

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.

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

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.

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.

in this Flightglobal page;

I suggest that,

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

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?

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

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): McDonnell-XV-1-Helicopter-blueprint-plans-report-1950s-RARE.jpg
