Westland Wyvern
Последним боевым самолетом, серийно выпускавшимся компанией «Westland», стал W34 - одноместный палубный ударный самолет, создание которого осложнялось выбором нового 24-цилиндрового двигателя Rolls-Royce Eagle с гильзовым распределением, разработанный под требования N.11/44 британских ВМС. Причем планер самолета должен был допускать простую и быструю замену этого двигателя на турбовинтовой - как только представится возможность.
Первый из шести прототипов Wyvern был облетан 12 декабря 1946 года, за ним последовали 10 предсерийных Wyvern TF.Mk 1 с двигателем Eagle. Данный мотор имел много проблем, поэтому доводочные летные испытания затянулись настолько, что еще до того, как было принято решение о серийном выпуске этих самолетов, стала возможной установка на них уже турбовинтовых двигателей.
В итоге выбор пал на двигатель Armstrong Siddeley Python - им решили оснастить 20 предсерийных Wyvern TF.Mk 2, 13 из которых поступили к заказчику именно под таким обозначением, остальные же были построены как серийные Wyvern TF.Mk 4 (позднее Wyvern S.Mk 4). Аналогичный двигатель был использован на 90 серийных S.Mk 4, первый из которых поступил на вооружение в мае 1953 года - примерно через шесть с половиной лет после первого полета прототипа. Самолет позже поступил на вооружение 827-й, 830-й и 831-й эскадрилий.
830-я эскадрилья стала единственной, использовавшей самолет Wyvern в боевых действиях - во время Суэцкого кризиса. Самолет оставался на вооружении до марта 1958 года, когда была расформирована 813-я эскадрилья.

Air Enthusiast 1998-03 / J.Smith - Wrath of a Mystical Monster
Westland Wyvern S.4 WN328 of 830 Squadron, HMS ‘Eagle’ (hence fin-code ‘J’). Abandoned following damage from light anti-aircraft fire during a raid on the Coast Guard Station near Gamil airfield, November 5, 1956. Pilot, Lt Cdr Bill Cowling ejected successfully and was rescued by helicopter. Aircraft was coded ‘371’ but this was obliterated by the application of ‘Suez stripes’ to the rear fuselage. Spinner and finlets were painted maroon. Note that the finlet does not appear to carry the diagonal yellow stripe (or stripes) usually carried. (This maroon and yellow was called ‘custard and prunes (or plums)’ by squadron personnel.

Prototype W.34 Wyvern TS371 first flew on December 23, 1946, powered by a Rolls-Royce Eagle 22 piston engine. Note that it lacks a wing-folding mechanism, cannon armament and ‘sting’ type arrester hook. It is seen here during its fatal last flight on October 15, 1947 in the hands of Peter Gamer - failure of the pitch translation bearing resulted in the airscrew stopping and the aircraft was burnt out in the ensuing unsuccessful wheels-up, dead-stick landing near Yeovil.

Massive Westland Wyvern TF.2 second prototype VP113 provided a snappy display, thanks to the power of its 4,000 e.h.p. Armstrong Siddeley Python turboprop engine: after unfolding its wings in front of the crowd it made a rapid take-off, upward-rolled with ease, flew inverted and made tight, fast turns within the airfield perimeter. The excellent field of view from the high-set cockpit attracted favourable comment, as did the ejection seat - unusual equipment for a propeller-driven aircraft.

This photo of TS375 from the rear highlights the Youngman flaps, seen extended in the “cruise” setting. This type of flap had proved itself on the wartime Fairey Barracuda and Firefly, acting as a slotted flap for take-off and landing or as an auxiliary aerofoil to increase wing area and efficiency to extend endurance in cruising flight.

Aviation Historian 22 / M.Willis - "Very nearly a good aeroplane..."
With a strap placed around its rear fuselage. TS375 is prepared for a tethered engine test run. Only a few early test Eagles had been built before 15 examples of the 3,500 h.p. Eagle 22 were produced by Rolls-Royce, largely for the Wyvern test programme. The prominent gills in the forward part of the cowling are the outlets for hot air passing over the intercoolers, which were arranged in a semi-annular fashion around the reduction gear.

Aviation Historian 22 / M.Willis - "Very nearly a good aeroplane..."
The second Westland Wyvern prototype, TS375, has its Rolls-Royce Eagle sleeve-valve engine run up at RNAS Merry field, a satellite of RNAS Yeovilton, around the time of its first flight in September 1947. The noise from the massive powerplant and its eight-bladed contra-rotating propeller must have been deafening, and at least two of the bystanders are, quite sensibly, covering their ears!
-
Aviation Historian 22 / M.Willis - "Very nearly a good aeroplane..."
The test crew assembles for the tethered engine run, and the Wyvern is fuelled from a small Brockhouse-type bowser. The battery trolley has also been plugged in. Note the square carburettor intake under the nose, wedged between the annular intercooler intakes, and the staining along the forward fuselage from the exhaust.

Aviation Historian 22 / M.Willis - "Very nearly a good aeroplane..."
Seen here from the front in “clean” configuration, with flaps retracted, TS375 did not have folding wings or any armament fitted; the first two prototypes were purely aerodynamic and systems test vehicles. The first prototype, TS371, was lost in a fatal crash little more than a month after TS375 first flew.
-
Aviation Historian 22 / M.Willis - "Very nearly a good aeroplane..."
As Westland’s factory at Yeovil was not suitable for the Wyvern’s early test flights, much of its development flying was undertaken from Merryfield. Here we see TS375 in front of a T2 hangar, with engineers working on the complex Rotol propeller. Only the rear blades are yet in place; the apparatus to lift the front blade unit into place may be seen to the left.

Aviation Historian 22 / M.Willis - "Very nearly a good aeroplane..."
A different Wyvern and possibly a different location - the aircraft is probably the third or fourth of the original six prototypes. Of the Eagle-powered machines, only TS378 and TS380 appear to have worn the post-war Admiralty colour scheme of Extra Dark Sea Grey over Sky as seen here in this group shot. The location is hard to establish, although it may be Merry field or even Rolls-Royce’s aerodrome at Hucknall. The gentleman in the white shirt and spectacles is believed to be Dennis Edkins, Wyvern designer Teddy Petter’s assistant.

The Westland Wyvern TF 4 seen here was the only production turboprop fighter to be built, not just in Britain, but the world. It was an ill-starred venture from the beginning. However, before reviewing the Wyvern and its closest US contemporary, the need for a turboprop front-line combat aircraft in the post-World War II jet era, must be considered. The turboprop engine may have had its limitations in terms of out-and-out speed as the propeller tips encountered compressibility shock, but it was lightweight and powerful. This aspect of the turboprop had been grasped by would-be engine producers by the early 1940s, some time before the first flight-worthy units existed. One particular design approach that found favour first in the US, was to couple two turboprops together to drive contra-rotating propellers through a combining gearbox. This type of turboprop had particular appeal to naval forces, who saw the advantages of eliminating take-off torque reaction from a confined flight deck as a marvellous plus point. As a bonus, they could shut down one of the units in cruise flight to economise on fuel. In Britain, the Royal Navy already had Westland developing the Wyvern by the end of World War II, albeit in piston engined form, using the Rolls-Royce Eagle. What could be simpler than changing engine from piston to turboprop? As it turned out, the desk-bound naval warrior's 'chop and change' approach failed, with the usual British procurement vacillations complicating more fundamental problems concerning the development of the generic turboprop, and deadlines were not met. The first turbo-proppowered Wyvern, the TF 2, took to the air on 18 January 1949, this with the 4.030eshp Rolls-Royce Cyde. Even before this flight, it had long been decided to put the Wyvern into production, as the TF 4, using the 4,110eshp Armstrong Siddeley Python. First flown with the Python on 22 March 1949, the TF 4 was reluctantly given its restricted service release over four years later, in May 1953. Incidentally, the intervening and protracted development programme that was predominantly propulsion-centred, was strewn with fatal crashes. Propulsion troubles continued to plague the Wyvern to the end, most flying from shore prior to an early service withdrawal in March 1958.

Skeletons in the cupboard include (left to right):
Westland W.34 Wyvern TF. Mk. 1 (VR133), one of the ten production models of the piston-engined Wyvern. The eight-blade Rotol contraprop was driven by a 2,690-h.p. Rolls-Royce Eagle, with twenty-four cylinders arranged in H-fashion. (Silver overall.) Blackburn B.54 (YA-5), the first prototype (WB781) of this two-seater, powered by a Rolls-Royce Griffon engine driving contra-rotating propellers, flew for the first time on 20th September 1949. The second prototype (WB788), also carrying the type number B.54, was a three-seater and was designated YA-7. It was an interim test vehicle designed to the Fairey Gannet Naval Specification GR.17/45. Experience was gained with this machine, powered by a Rolls-Royce Griffon, and paved the way to the turboprop-powered (2,950-e.h.p. Armstrong Siddeley Double Mamba A.S. MD.l) three-seater YB-1 (WB797) which flew for the first time on 19th July 1950. Type number was B.88. (Dark sea-grey top, duck-egg blue undersides.)

Conceived in 1944 as a long-range naval fighter, the prototype Wyvern first flew on December 16, 1946, with Harald Penrose in the cockpit. On January 18. 1949, the first turboprop-powered Wyvern T.F.2, powered by the Rolls-Royce Clyde, took to the air, followed on March 22 by the first Armstrong Siddeley Python-engined aircraft. The Python became the standard powerplant for the Wyvern, and after protracted development flying, the Fleet Air Arm took delivery of its first aircraft in 1935. The final service variant was the T.Mk.4 (later S.Mk.4), which began carrier operations late in 1954 and served as a front-line strike fighter until 1958, seeing action with 850 Squadron during the Suez crisis in November 1956.
