Hi all,

I'm looking for a drawing (preferably 3-view) of Westland's original Wyvern design with the Rolls Royce Eagle engine. Thanks!
 
I can only provide a side view I'm afraid, but I'll throw in a photo of the real aircraft as a bonus :D:

There are detailed multiviews (6 way I think) and lots of pictures in
Westland Wyvern 4_016 Mark 1 publications mark1@cmail.cz
 
Sorry - a rather important typo

This series is 4+ publications. the Wyvern being number 016
 
I'm looking for either of the above. All I found thru Google was an all black silhoutte (no detail) side view of it. A couple of Wyvern books I have have mention it but about all that's mentioned is 3 bladed c/r props. Thanks in advance if anyone has anything.
 
The only thing I have is this, from Gunston's 'Rolls-Royce Aero Engines', page 119,
THe Clyde powered Wyvern, VP120, and a picture of the Clyde engine itself,
from page 117 of the same book...

EDIT. Found another one, from Putnam's 'Westland', page 295, showing the
engine running.


cheers,
Robin.

By courtesy of lark, I got an article from Flypast about the heritage of Stanley Seager, working for
Westland in the years of 1917 to 1969, as a designer after his years of apprenticeship. Besides
other stuff, there were two handmade sketches of trainer variants of the Westland Wyvern torpedo
fighter. Not much seems to be known about them, so I just tried to sketch them as 3-views.
The first is a layout for Westlands response to the T12/48 specification, that later emerged as the
T.3. Obviously it had a 2-men cockpit with tandem seating, but with a completely new canopy,
whereas in the T.3 two standard canopies were used, connected by a perspex tunnel, maybe just
as a cheaper and quicker solution. The additional fins are absent, maybe an indication, that this
design was made, when the need for them still wasn't apparent.
The other sketch shows a trainer with a wider canopy, so probably featuring side-by-side seating,
as generally preffered by the Britsh during that time. Although still using contra props, the engine
and its cowling are slimmer, suggesting a lighter, less powerful engine, than the Armstrong Siddeley
Python of the S.4/T.3 . No fins here, too, but the central fin/rudder looks bigger. Maybe this was a
proposal to field a Wyvern derivative as as contender to turboprop trainers like the Avro Athena.
Strange detail, that both proposals seem to carry the full armament of four guns.
(I split and moved the posts about the Wyvern from the thread in the Early Projects section, as
the Wyvern, although answering a wartime specification, came to its own not before the war had
ended)

It can be difficult to know what to do about these. e.g. Tony Buttler put the B-36 into the postwar American Bombers book despite it beginning its development in WW2 because, to use his words, it shaped what followed - but on the other hand, the Avro Shackleton appears in the 1935-1950 book even though its service didn't end until the 1990s.

[/size]I suppose they envisaged it as a gunnery trainer as well as for conversion onto type.

Yes, maybe, although i think, two guns, one in each wing would have been sufficient (and
cheape !) just for training purposes. But as I understand, Stanley Seager did some of those
sketches from memory and although still using "MS Paper & Pencil", of course, he maybe just
started each sketch with the "standard" Wyvern, as a kind of manually copy & paste.
 
Wow,Amazing projects my dear Jemiba,


and great thanks to my dear Lark.
 
Wyvern W.36.

"The never-built variants of the Westland Wyvern.
The first W.34 design in mid-1944 penned by W.E.W. Petter had the Rolls-Royce Eagle behind the cockpit for excellent landing visibility and it was slightly smaller than the TF.Mk.I as built. Top speed was estimated at 420mph, all-up weight 17,300lbs. There was brief RAF interest in an escort fighter version but in the end Spec the aircraft was developed to N.11/44 for the Navy. The desire to upgrade to turboprops was built into the design, probably one reason why the layout was altered to a more conventional engine-first layout.

The W.36 was a Wyvern with a jet-engine drawn up in 1946. It would have had either a Rolls-Royce AJ.65 (became the Avon) or a Metrovick F.9 axial-jet. The plan seems to show six cannon, two in the nose and four in the wings, the exhausts were planned as flush outlets but I think this would have been modified if built into a nib-pipe like the Sea Hawk. Oddly, this split tailpipe arrange would have allowed the retention of a tailwheel undercarriage, nothing on the plan indicates a nosewheel.

The S.Mk.5E was proposed in March 1954 with a Napier E.141 Double Eland turboprop with wingtip tanks."

The brief information I put together for that shipbucket page was based on entries in Tony Buttler's BSP Vol.3 and the Westland Putnam.
Friedman in British Carrier Aviation also touched on the original mid-engine layout design.
 
Looking for TF.4 (S.4) Rotol props drawings / blades airfoils data. Any help is appreciated.
 
Can someone help with understanding those Rotol props designation numbers?

Why was the Wyvern withdrawn from service so quickly ? (1958)
It had some interesting features. In particular, a good range (1400 km).
Despite its low speed (~600km/h), it could still have been a very good attack platform until the mid 60s.
Has it been offered for export ?
 
Mainly because its engine was comparatively rubbish.
I don't think it was offered for export, even if it was, Hawker had the market sown up with the Sea Fury and Sea Hawk.
 
In the 5 years of service there were 68 Wyvern accidents, 39 losses & 13 pilot fatalities - out of 127 built including prototypes!
 
Westland ( and the Navy) wanted to use the Rolls Royce Clyde, as flown in the prototypes, but (according to the Great Gunston) RR refused a production order, preferring to concentrate on the Avon . . .

cheers,
Robin.
 
Is the flight performance for the Clyde-powered variant available? I've yet to find much information about it in regards to its performance. I would presume that the weapons fit was more or less identical to the T.F.Mk.1.
