Well aware
The Gnome wasn’t, originally, a R-R design was it? – neither was the Sea King a Westland design??:)
Roger Smith.
Thanks Smudge, I am well aware that the Gnome ECU was an Bristol Siddley engine itself derived from I think a G.E Design. As for the Sea king being a Sikorsky originally yes I am aware of that fact also. What you might not be aware of is that Westlands took this aircraft and built it under licence selling more to other countries than the Americans. Im sure this counts as some kind of success for Westlands. I have been working on Westlands aircraft from Whirlwinds,Wasp,Sea King,Lynx andd even the Merlin over the last 37 years they did a good job then and they still give sterling service today. The Sea King in particular is set to be further improved with its’ new Carson blades which will give it greater lift and speed characteristics.
Had the Wyvern not been developed at the dawning of the Jet age what kind of history might that Westlands design have had?.
P.s I am aware that S.R initially designed the Wasp/Scout.;)
Bad combination?
Does that go for the RR Gnome powered SEA KING?:confused:
TF 2 at Gosport
Is it posible that the photograph of the second Wyvern a TF Mk 2 could have been VW 870 prior to its removal to Bramcote as a GIA classII airframe. This would make it 1957. Would it be possible to confirm the date of the photos please
slow compressor response
The power output on the python was a major cause for concern with a moment of lag between the throttle being moved and a subsequent response.The cause of the lag was due to inertia within the engine.This lag was minimised by the fitment of a hydraulic servo between the propellor constant speed unit and the throttle lever. This however didn’t completely alleviate the problem.Most approaches to carriers made a live cut to execute a landing, not possible in the Wyvern as response times were too slow. To this end a constant speed landing was used with prop control used.The constant speed unit was replaced with a propellor control unit and a forecasting unit to eliminate the problem with lag.This was fitted to pre production TF2 ‘s onward.These problems persisted and aircraft were limited to mainly shore ops only.Eventually a system known as an engine control unit was made available but not until mid 1954.
Buried Naval Heritage
I know the interest surrounding this thread is to cover the Wyvern buried at Gosport. However in line with policy at the time burial was a useful way of getting rid of the excess airframes. In my F.A.A service days i was told of a similar site at R.N.A.S Culdrose which was sited along the Gweek road. This site was reported as containing crated airframes and ecu’s mainly from Early Firefly’s anyone heard this before? As the road that went to Gweek has been long re-located this site if it excists will be well within the airfield boundary fence, so no excavating this one chaps! 🙁

Historic burial site
Thanks Lee, you are correct in what you have said about the Wyvern site. The area of outstanding beauty isn’t exactly that but borders an area that now has a ‘replica’ historic site and it was under this excuse that interested parties were refused a dig at the site. It is of some interest however that the mention of a ‘Chalk pit’ might be misleading as the area is predominately plataeu gravel. Geologically the Bracklesham beds pass through this area above what is Oxford clay. As it is known that the gravel beds go down about 75 ft it is more likely that any airframes are buried in this medium. :confused:
A note on the Eagle engine that you mentioned, I have a friend within the F.A.A Museum and posed the same question about the one that you say was ‘kicking around’. It would seem from my contact that this is in fact a scale working model but hardly full size….Pretty impressive though!
Gosport Wyvern
This is my first attempt at a Forum …….So i apologise at this stage for being a noob!
I have been following this thread with great interest as I am a collector of all things to do with the Wyvern. Firstly it is well known locally as to the whereabouts of the burial site of this particular Wyvern, it is also possible that a second airframe also exists! As to the possibility of its removal, previous attempts at gaining permission have met with a stone wall. If my reply to this thread is of interest to anyone I will at a later date fill in the gaps so to speak.
I am well placed to investigate this area as I work for the Defence College of Aeronautical Engineering now based at Gosport on the old Grange/Siskin site,we in fact use some of the same hangars previously used to house the same Wyverns buried locally. The pit to my knowlege wasn’t fired.
