Westland Wyvern S4

by Kazunori Ito

*******************************************************************************

I'm taking a rest..............
I challenged the aircraft that was able to be made comfortably.
A little old and small aircraft may be easy to make it.

It is difficult in the latest aircraft to make it because there are a lot of seamless parts.
F-22 was also so.
Though Mirage2000 is demanded, making is not easily started because this also has a seamless part.

What will I make as next?

-------------------------------------------------------------------------------

The Westland Wyvern was a British single-seater strike aircraft. It began life as a 'Torpedo Fighter', intended to operate as daylight fighter and torpedo bomber. Designed by John Digby, it was a large aircraft because of the large engine (24 cylinders) and the intention to fit a turboprop at a later date.

The first piston-engined Wyvern (TS371) took to the air on 12 Dec 1946 with Harold Penrose at the controls. It soon established a bad reputation, mainly due to problems with the engine and propeller. Only fifteen piston-engined Wyvern's were built.
Two turboprop engines soon became available, the Rolls-Royce Clyde and the Armstrong Siddeley Python A.S.P.3. The Clyde (rated at 4,030 HP with a potential for much more) was Westland's preferred engine and it fitted into prototype VP-120 successfully. But the engine never went into production because Rolls-Royce wished to focus on turbojet production.

So Westland was forced to use the older Python engine of 3,760 HP which provided a top speed of 616 kmh and a range of 1455 km. This engine gained a bad reputation, being unreliable and having a slow reaction time. These problems were never satisfactorily resolved and the aircraft became very unpopular with those who had to fly it, one test pilot even considered the Wyvern lethal.

Carrier trials began on 21 Jun 1950 and the aircraft entered service in May 1953. It was in service with the Fleet Air Arm from 1954 to 1958 when it was withdrawn from service. It saw action against Egyptian forces in 1956 during the Suez crisis, 830 squadron seems to have been the only one that made any combat flights, losing 2 aircraft in 79 sorties.

A later version, the TF.4 had numerous small changes. Martin-Baker Mk. 2B ejection seats were installed and the cockpit was reinforced. Later modifications included perforated dive brakes, a flat windscreen, and provision for tip tanks.

Total production: 127 Westland Wyvern's were made.

Please copy all files in the \gauges folder onto the gauge in the Gauges folder of FS2002 or FS2004.
A general gauge is saved for the gauge bundled this time.

[ About the directions point in FS2004 ]

This aircraft can be basically used also with FS2004 because it is made with FSDS Ver. 2.24 .
However, the aerofoil tip might not be able to enter in the screen in the spot taking a picture view because of very wide the width of the aircraft.
Please switch to the spot taking a picture view with other aircraft when this state happens seeming this as it is because the magnification switch of the spot taking a picture doesn't operate well.
Afterwards, if this aircraft is chosen by selecting the aircraft, it is sure to be displayed by a normal magnification.
