Hawker Sea Hawk

   Прототипы самолета Sea Hawk - одного из наиболее эстетичных образцов творчества Сидни Кэмма - были построены в соответствии со спецификацией 7/46. Первый из трех опытных самолетов, обозначенный P.1040, поднялся в воздух 2 сентября 1947 года. После получения контракта компания построила 35 истребителей Sea Hawk F.Mk 1, затем производство и доработка полностью перешли к компании "Armstrong Whitworth". Еще 60 истребителей Sea Hawk F.Mk 1 и Sea Hawk F.Mk 2 были построены последней компанией, а затем был создан истребитель-бомбардировщик Sea Hawk FB.Mk 3, отличавшийся усиленным крылом. После выпуска 116 самолетов Sea Hawk FB.Mk 3 последовали 97 истребителей/штурмовиков Sea Hawk FGA.Mk 4. Все варианты, включая и последний самолет, были оснащены двигателем с двойным соплом Rolls-Royce Nene Mk 101 тягой 22,24 кН, позволявшим разместить топливо в хвостовой части фюзеляжа.
   Установка на некоторые самолеты Sea Hawk FB.Mk 3 двигателя Nene Mk 103 привела к появлению модификации Sea Hawk FB.Mk 5. Кроме того, для британского флота были построены 86 самолетов FGA.Mk 6, также оснащенных двигателем Nene Mk 103, но в остальном идентичных модификации Mk 4. Sea Hawk эксплуатировался в ВМС до конца 1960 года, а 22 экспортных варианта Sea Hawk Mk 50 находились в Королевских ВМС Нидерландов до конца 1964 года. Другими основными экспортными вариантами были: Sea Hawk Mk 100 и всепогодный Sea Hawk Mk 101, заказанные морской авиацией Западной Германии. Они были аналогичны модели FGA.Mk 6, за исключением более высокого вертикального оперения. Кроме этого, на Mk 101 в обтекаемом контейнере под правым крылом была установлена поисковая РЛС Ekco Type 34. Самолеты действовали с береговых аэродромов, и только в середине 1960-х годов им на смену пришел Lockheed F-104G Starfighter.
   Осенью 1959 года ВМС Индии - последний эксплуатант данной машины - заказали 24 самолета Sea Hawk FGA.Mk 6, часть из которых была заново построенными, а остальные являлись отремонтированными самолетами Mk 6 из состава авиации британского флота. Самолеты поступили в 300-ю эскадрилью, приписанную к авианосцу "Викрант", а позже к ним добавились еще 12 самолетов модификаций Sea Hawk FGA.Mk 4 и FGA.Mk 6, ранее принадлежавших морской авиации Великобритании, плюс 28 самолетов Hawk Mk 100 и Mk 101, переданных из Германии. Последние из всех этих машин в конце 1980-х годов были заменены на самолеты BAe Sea Harrier.

Nose view of the Hawker P.1040 prototype VP401, September 1947.
A rear view of VP401 at Boscombe Down in September 1947. The first prototype was originally fitted with a Rolls-Royce Nene I centrifugal-flow turbojet engine of 4,500lb-thrust, later replaced by a more powerful Nene II of 5,000lb-thrust. The mainwheels, attached to the centre-section stub wings, retracted neatly into the fuselage.
The shape of things to come - VP401 as first flown in September 1947 at Boscombe Down, with the original rectangular exhaust fairings and a nose-attitude reference mast ahead of the cockpit. Interestingly, in its issue of September 5, 1947, British weekly aviation magazine The Aeroplane referred to the P.1040 as the "Zephyr”, although it offered a correction the following week stating that it was in fact not so named.
Progenitor of the line which culminated in the Hunter was the P.1040
Самолет с бортовым номером VP401 - прототип P.1040, разработанный в последние военные месяцы. Первый полет машина выполнила 2 сентября 1947 года. Самолет стал основой для создания двух прототипов по спецификации N.7/46 Королевского ВМФ.

Showing off its extremely clean lines, VP401 was captured in this magnificent air-to-air study by Hawker’s regular photographer Cyril Peckham in 1948 or 1949, with Wade at the controls. Shown to good effect in this head-on view are the type’s air intakes and relatively thin outer wing sections, with a thickness-to-chord ratio of 0.095:1.
One of the most aesthetically pleasing jets ever, the Hawker P.1040 prototype VP401.
Sporting the revised canopy, with a flat windscreen on the forward section, VP401 is seen here at Langley for its first public display on August 24, 1948. During it, according to The Aeroplane, Trevor Wade ‘‘did full justice to the occasion and showed the paces of his mount in one of the ablest displays we have seen for some time”.

For its first flight on September 2, 1947, VP401 was sent to Boscombe Down, which had a more suitable runway than Langley’s grass. Three days after its maiden flight the aircraft went to Farnborough, for the continuation of trials.
Sporting red/orange bands around the rear fuselage and racing number “87", VP401 awaits its next race at Elmdon in July-August 1949. To the left is Blackburn Firebrand EK621, which raced against VP401 for the Kemsley Challenge Trophy, and to the right, D.H.108 VW120, which lost out to VP401 in the SBAC Challenge Cup.
Another photograph of VP401 at Elmdon, this time refuelling in front of D.H.103 Hornet PX386, which was to compete against VP401 in the Kemsley Challenge Trophy race - which the N.7/46 won, piloted by Neville Duke. With the introduction of jets, the UK’s National Air Races truly represented the ‘‘fastest racetrack in the world”.
With the fitting of an Armstrong Siddeley Snarler rocket motor in its extreme tail in the early summer of 1950, VP401 became the P.1072 experimental research aircraft. The Nene engine remained largely unaffected, but the entire fuel system was revised, with the aircraft’s original 395gal turbojet fuel load reduced to 175gal.
VP401 has its Snarler motor refuelled, the liquid oxygen vapourising on contact with the air. The Snarler’s inspection panels have been removed, as has the fairing over the external pipework channelling fuel and propellant from the tanks located forward of the jet engine along the underside of the fuselage.
The business end of the P. 1072 - VP401 following modification to P.1072 specification, showing the combustion chamber of the Snarler. Owing to modifications to the tail to accommodate the rocket motor, the rudder lost some area at the bottom.
The first Hawker P.1040, VP401, was later fitted with a Snarler rocket and became the P.1072.
P.1040 VP401 was converted to mixed powerplant format with an Armstrong Siddeley Snarler rocket as well as the Nene, as the P.1072. It is illustrated at Bitteswell under flight test in mid-1951.
The first take-off of the P.1072 under rocket power, from Armstrong Siddeley’s airfield at Bitteswell on November 20, 1950, with Wade at the controls. The forward fuselage housed 75gal of liquid oxygen in a spherical tank, while aft of the rear paraffin tank was another tank carrying 120gal of water-methanol for the rocket motor.
The final curtain - VP401’s last major role was as part of the static display at the SBAC Show at Farnborough in September 1951. The P.1072 was presented by Armstrong Siddeley Motors rather than Hawker, although the relationship between the two manufacturers was displayed on the aircraft in the form of a Hawker Siddeley Group emblem on the nose.
The second Hawker N.7/46 prototype, VP413, photographed by Cyril Peckham after its completion. The type marked a radical change of direction for Hawker, but ultimately proved to be an excellent example of ingenious engineering solutions, remaining in service with the Royal Navy for more than 15 years.
The second N.7/46, VP422, which was used for preliminary service evaluation in 1950.
The finished article - a fine Cyril Peckham study of WF144, the second production example of the Sea Hawk F Mk 1. Only 35 Sea Hawks were produced by Hawker (apart from the prototypes) before production moved to Armstrong-Whitworth at Baginton. This aircraft differed from the prototypes by having square-ended elevators, a redesigned cockpit canopy and a longer arrester hook; otherwise it was very similar, lacking features of later production aircraft such as the “acorn” fairing at the intersection of the fin and tailplane and underwing weapon hardpoints.
The second production aircraft made carrier trials on HMS Eagle with WF145.
The second navalised prototype N.7/46, VP422, made its maiden flight in October 1949. It had a lengthened arrester hook, drop-tank pick-up points and provision for RATOG. Note the gun ports in the nose.
The first three production Sea Hawk F 1s WF144, WF143 and WF145.
"Си Хоук"
Although it is not specified in the material, it is likely that the aircraft seen being constructed in the preceding photographs was the second N.7/46 prototype, VP413 - which, unlike the first, included folding wings, catapult spools and full gun armament. The aircraft made its maiden flight on September 3, 1948, after which it went to Boscombe Down for dummy deck assessment trials. It was then flown on to HMS Illustrious, aboard which it is seen here, for take-off, landing and general handling trials.

The only jet type in the Historic Flight at present is the Hawker Sea Hawk WV908, which flies in the markings of 806 NAS, the well-known Ace of Diamonds squadron. Of other jet types that served with the Royal Navy, examples of only the Phantom FG Mk I now remain airworthy.
Hawker Sea Hawk WV908 flew for the first time after restoration at Culdrose on May 23, 1978. Its original maiden flight was on December 31, 1954, and it served as an FGA.4 with 807 and 898 FAA Squadrons and as an FGA.6 with 806 and 738 Squadrons before retirement on June 29, 1962. It now wears 806 Squadron markings.

LEFT The first image from the Hawker material shows a pressed light-alloy fuselage frame from the area of the wing-root intakes, illustrating the recesses where ducting will guide air to the Rolls-Royce Nene engine. The frame has been photographed upside-down; when installed in the airframe, the flat inside edge should be at the base. Notches in the outer edges of the frame are to accommodate the fuselage’s longerons and stringers.
RIGHT In terms of construction this light-alloy fuselage frame is conventional, although its shape is unusual. The “V” shape in the lower part of the frame was adopted to create space within the fuselage for the main undercarriage bay. The N.7/46’s thin wing left less space for the undercarriage than in previous piston-engined designs, while the large-diameter engine and the thicker wing roots required for the intakes left space free just aft of the engine, which Hawker used to house the mainwheels when retracted. The space in the upper half was for a saddle-type fuel tank sitting over the aft end of the engine. The wings were too thin to incorporate fuel tanks.
With the engine in the centre of the fuselage, the mainspar could not pass directly through, so a ring­frame had "outriggers" attached, taking the loads from the outer wing spars, in this case the rear spar that carried the flaps and ailerons. The central pillar bisecting the ring-frame passed between the two branches of the bifurcated jetpipe that Hawker and Rolls-Royce developed for the N.7/46. The diagonal flanges on the ring-frame indicate the inner surface of the undercarriage bay, of which this frame formed the aft face. The frame seen (from the rear) in this photograph has been placed in the main fuselage construction jig. The fuselage was constructed in three main sections - the central part, as seen here, the nose section and the rear fuselage and tail section.
TOP The central fuselage further along in its construction in the jig, looking forward. More frames have been added, forming the backbone of the aircraft. This section would eventually contain the engine and its associated intake trunking, the frames with their recesses for which, as in the first photograph, may be seen at the forward end of the assembly. This sub-assembly would also contain the engine exhaust system, the main undercarriage bays and form the wing/fuselage connection. It demonstrated the biggest difference from piston­engine practice in this transitional jet design.
BOTTOM The same assembly seen from the forward end, now with the skin attached, and the wing root added. This image shows how the intake air was guided from the wing-root intake, the shape indicated by the bracing rods between the fuselage and the large inner wing rib, into the central fuselage to feed the Nene engine’s prodigious (for the time) mass-flow requirements.
The forward fuselage section from a port three-quarter view, with the majority of the frames now in place. Armament was included on the second and third N.7/46 prototypes; VP413 was the first to be equipped with the planned four 20mm Hispano cannon in the underside of the nose, two of which may be seen midway along the section. Note the hollow in the frames adjacent to the gun bay to allow clearance for the cannon’s blast tubes. The upper half of the sub-assembly is open, as this is where the cockpit will ultimately be sited.
TOP The rear fuselage was relatively simple compared with the central and nose sections, both of which had to incorporate a great deal of equipment and house major items such as the engine and cockpit. Here the light ring-frames have been positioned in the jig, running aftwards from left to right. Note the transition from those furthest forward, which are of a broadly circular cross-section, to much thinner oval-section frames at the aft end. The semi-monocoque rear fuselage structure consisted of a total of 15 of these light frames and 16 stringers supporting the skin.
BOTTOM Rather than the longerons and stringers for the rear fuselage being connected directly to the frames before skinning, a number of pre-formed sections of outer skin with stiffening already attached were built up and fitted to the frames after their assembly. This is the lower fuselage section; but all the skin panels were of similar form, with hatch openings pre-cut, as seen here.
The forward fuselage has now been joined to the nose section, and skinning has begun. Note the oval-shaped recess behind the trailing edge of the wing root, through which the starboard section of the bifurcated jetpipe exited. The main undercarriage bay is visible beneath the aft part of the wing-root. The sloping bulkhead towards the nose, with the protruding half-circle at the top, would have the pilot’s ejection-seat rail attached to it. The half-hoop at the forward end is the aft frame for the windscreen, which was integral to the nose section. The open rectangular panel beneath it incorporated access to the guns’ blast tubes.
The first prototype Hawker P.1040, what would become VP401, under construction at Hawker’s Kingston factory, in late 1946. The forward and rear sections of fuselage, built as individual sub-assemblies, have been skinned and joined.
TOP The Rolls-Royce B.41 engine, known in production as the Nene, was essentially a version of the same company’s Welland, scaled-up and improved via lessons learned from the USA’s General Electric/Allison J33. The Hawker P.1035/P.1040 was designed around the engine, which became the most powerful jet in production for a spell in the late 1940s. The engine is seen here from the port rear side. A manifold would be attached to the aft end of the engine, to which each jetpipe would be fitted. The jointed tubes at the top of the engine were part of the N.7/46 installation; the sockets at the rear attached to fittings on a ring frame inside which the engine sat.
BOTTOM Parts of the characteristic twin jetpipes, central to the N.7/46’s design, developed by Rolls-Royce and Hawker specifically for the type. Note how they curve, initially splaying outwards before bending inward to direct the jetflow more in line with the aircraft’s axis. The rear of the jetpipe is closest to the camera on the left-hand item (marked "STBD", i.e. starboard) and furthest from the camera on the right-hand jetpipe.
The pre-skinned rear fuselage section has now been mated to the central fuselage, and the main structure is complete. The base of the fin was integral with the fuselage, as the tail was of cruciform design with the tailplane mid-mounted on the fin - a compromise between raising it clear of the jetwash and avoiding the higher weight associated with a T-tail. Note the frames of another N.7/46 in their jigs in the background - possibly the third prototype, VP422.
The mainplane structure of the N.7/46, which was a notable advance on the preceding Sea Fury in several respects. The almost total lack of stringers is evident here, with stiffness imparted instead through a thicker-gauge skin, a practice learned from American manufacturers during British engine genius Roy Fedden’s mission to the USA during the Second World War. The straight leading and trailing edges simplified manufacturing, while the "high-speed" aerofoil - with maximum thickness at around 40 per cent chord (note how far aft the main spar is) and a 9-5 per cent thickness to chord ratio (compared with 14 per cent for the Sea Fury) - significantly improved performance.
TOP An N.7/46 elevator in its construction jig, showing generally similar construction to the mainplanes. Note the elevator’s curved outboard end; this feature was only included on the prototypes, and production elevators were square-ended. The forward edge shows the balance and flange for the aerodynamic "seal strip", which prevented air leaking between the upper and lower surfaces of the tailplane.
BOTTOM The fin, with its starboard face skinned, showing its longitudinal and vertical ribs. The slot in the trailing edge housed the rudder’s balance tab. This is only the upper part of the fin; the lower part was integral with the fuselage and the curvature of the lower edge corresponds to the upper surface of the tailplane.
