It was a Mark XIV which was the first Allied plane to bring down a Messerschmitt Me 262, the worlds first operational jet fighter. The appearance of the Me 262, however, showed the way to the future. It is one of only four flying MK 1 Spitfires in the world. The dive put the aircraft to Mach 0.92, the fastest ever recorded in a piston-engined aircraft, but when the propeller came off, the Spitfire, now tail-heavy, zoom-climbed back to altitude. First flown in March 1936, it was designed as a short- range defensive fighter for rapid interception of raiding fighters and bombers. [nb 8] The radiators were housed in a new radiator-duct designed by Fredrick Meredith of the Royal Aircraft Establishment (RAE) at Farnborough, Hampshire. Mitchell has sometimes been accused of copying the wing shape of the Gnter brothers-designed Heinkel He 70,[63] which first flew in 1932, but as Beverley Shenstone, the aerodynamicist on Mitchell's team, explained: "Our wing was much thinner and had quite a different section to that of the Heinkel. Most of the Spitfires with which the RAF fought the Battle of Britain were Mark Is, but work had begun on a Mark II as soon as the first model had gone into production, and some were already in service as early as the summer of 1940. [72] This caused the wing roots to stall before the tips, reducing tip-stall that could otherwise have resulted in a wing drop, often leading to a spin. [37] By the time production ended at Castle Bromwich in June 1945, a total of 12,129 Spitfires (921 Mk IIs,[38] 4,489 Mk Vs, 5,665 Mk IXs,[39] and 1,054 Mk XVIs[38]) had been built, at a maximum rate of 320 per month, making CBAF the largest Spitfire factory in the UK and the largest and most successful plant of its type during the 193945 conflict. Machine guns, cannon, gun sight and original working radios are all installed. Both restored by American billionaire Thomas Kaplan, one has been donated to the Imperial War Museum and the second was auctioned in July 2015 at Christie's, London. (adsbygoogle = window.adsbygoogle || []).push({}); 2022 Current Publishing. In June 1939, a Spitfire was fitted with a drum-fed Hispano in each wing, an installation that required large blisters on the wing to cover the 60-round drum. Download the Spitfire Audio App to start your Spitfire journey. "The Birth of a Thoroughbred.". With regard to physical health, our guests are required to enter and exit the aircraft unassisted. I agree with PW that in AmE, the term is mostly positive . This is a solid and versatile foundation for all your brass needs capable of everything from solo and chamber groupings to rich symphonic sounds. [80] The other wing-tip variation, used by several Spitfire variants, was the "clipped" wing; the standard wing tips were replaced by wooden fairings which reduced the span by 3ft 6in (1.07m). Small, affordable convertible roadster built by Triumph from 1962 until 1980. In 1931, the Air Ministry released specification F7/30, calling for a modern fighter capable of a flying speed of 250mph (400km/h). The fabric used for aircraft control surfaces had to be as light and as strong as possible: On the ground, the flaps were normally lowered only for inspection or for maintenance. In 1942, the United States acquired a flyable, Japanese, This aircraft survived the war, only to be scrapped in 1945. From February 1943 flush riveting was used on the fuselage, affecting all Spitfire variants. While it did not cure the problem of the initial fuel starvation in a dive, it did reduce the more serious problem of the carburettor being flooded with fuel by the fuel pumps under negative "g". [45][46] Alex Henshaw, chief test pilot at Castle Bromwich from 1940, was placed in charge of testing all Spitfires built at that factory. [14][nb 2] This eight-minute flight[12] came four months after the maiden flight of the contemporary Hurricane. Both were shot down and became prisoners of war, while flying Spitfires over France in 1941 and 1942. Nevertheless, 30 more cannon-armed Spitfires were ordered for operational trials, and they were soon known as the Mk IB, to distinguish them from the Browning-armed Mk IA; they were delivered to No. As a result, the Spitfire's performance and capabilities improved over the course of its service life. Greenwood Military Aviation Museum is also home to a replica non-flying Spitfire. On the other hand, the Bf 109's Revi gunsight was far ahead of the early Spitfire's ring-and-bead type sight. These include the Jurca Spit from France, and those manufactured by Tally Ho Enterprises in Canada. [184] Supermarine Aircraft originally from Brisbane, Australia, and now based in Cisco, Texas manufacture the 80% scale Spitfire Mk26 and the 90% scale Mk26B replicas. [38] Different wings, featuring a variety of weapons, were fitted to most marks; the A wing used eight .303in (7.7mm) machine guns, the B wing had four .303in (7.7mm) machine guns and two 20mm (.79in) Hispano cannon, and the C, or universal, wing could mount either four 20mm (.79in) cannon or two 20mm (.79in) and four .303in (7.7mm) machine guns. And compliments to a strong woman should also be specific. The fuselage plating was 24, 20, and 18 gauge in order of thickness towards the tail, while the fin structure was completed using short longerons from frames 20 to 23, before being covered in 22 gauge plating. Completed Spitfires were delivered to the airfields on Commer "Queen Mary" low-loader trailers, there to be fully assembled, tested, then passed on to the RAF. Shores, Christopher and Brian Cull with Nicola Malizia. The Spitfire Audio App, previously known as the "Spitfire Audio Library Manager" is the downloader application for our libraries. These included a 4 Squadron SAAF Mk VB in North Africa, where a second seat was fitted instead of the upper fuel tank in front of the cockpit, although it was not a dual-control aircraft, and is thought to have been used as the squadron "run-about". [60] In some areas, such as at the rear of the wing and the lower tailplane skins, the top was riveted and the bottom fixed by brass screws which tapped into strips of spruce bolted to the lower ribs. [143] Early Seafire marks had relatively few modifications to the standard Spitfire airframe; however cumulative front line experience meant that most of the later versions of the Seafire had strengthened airframes, folding wings, arrestor hooks and other modifications, culminating in the purpose-built Seafire F/FR Mk 47. The removable wing tips were made up of duralumin-skinned spruce formers. Spitfire Audio app. Keith held various appointments with the RAF dealing with designing, development and technical policy of armament equipment. The early Mark Is had a service ceiling of 31,900ft, and at 30,000ft could reach a speed of 315mph. NEAR MINT . [95][nb 11], In March 1941, a metal disc with a hole was fitted in the fuel line, restricting fuel flow to the maximum the engine could consume. Constant problems with the evaporative system in the Goshawk led to the adoption of a cooling system which used 100% glycol. This mark could nudge 400mph (640km/h) in level flight and climb to an altitude of 33,000ft (10,000m) in under nine minutes. [147], The first Rolls-Royce Griffon-engined Mk XII flew in August 1942, and first flew operationally with 41 Squadron in April 1943. After the war, designers everywhere turned to the production of jet-engined fighters. Increasing numbers of Spitfires were also being sent to the Middle Eastern and Far Eastern theatres. Military archaeologist Keith Robinson celebrates the iconic design. In November 1934, Mitchell, with the backing of Supermarine's owner Vickers-Armstrong, started detailed design work on this refined version of the Type 300. This meant a Luftwaffe fighter could simply "bunt" into a high-power dive to escape an attack, leaving the Spitfire behind, as its fuel was forced out of the carburettor by negative "g". [146] Performance was greatly increased when later versions of the Seafire were fitted with the Griffon engines. Eric Brown, 'Wings on my Shoulders', 2007, p.74, Aeroplane & Armament Experimental Establishment, National Advisory Committee for Aeronautics, Supermarine Spitfire (early Merlin-powered variants), Supermarine Spitfire (late Merlin-powered variants), Supermarine Spitfire (Griffon-powered variants), Supermarine Spitfire variants: specifications, performance and armament, "British Design Classics" commemorative postage stamp, Allied Technological Cooperation During WW2, "Salisbury's secret Spitfire makers honoured with plaques", "Aeronautical research in Germany: from Lilienthal until today, Volume 147", "NACA Report on lateral control research, p. Between 1940 and 1946, Henshaw flew a total of 2,360 Spitfires and Seafires, more than 10% of total production.[47][48]. [28], As a result of the delays in getting the Spitfire into full production, the Air Ministry put forward a plan that its production be stopped after the initial order for 310, after which Supermarine would build Bristol Beaufighters. The cannon suffered frequent stoppages, mostly because the guns were mounted on their sides to fit as much of the magazine as possible within the wing. [93], Early in its development, the Merlin engine's lack of fuel injection meant that Spitfires and Hurricanes, unlike the Bf 109E, were unable to simply nose down into a steep dive. If all appeared satisfactory, I would then put her into a dive at full power and 3,000rpm, and trim her to fly hands and feet off at 460mph (740km/h) IAS (Indicated Air Speed). [137] Although the Spitfire continued to improve in speed and armament, its limited fuel capacity restricted range and endurance: it remained "short-legged" throughout its life except in the dedicated photo-reconnaissance role, when its guns were replaced by extra fuel tanks. The production test was usually quite a brisk affair; the initial circuit lasted less than 10 minutes and the main flight took between 20 and 30 minutes. [31], In 1935, the Air Ministry approached Morris Motors Limited to ask how quickly their Cowley plant could be turned to aircraft production. Instrument selection occurs at the very top, while realtime controls default to the upper part of the instrument GUI, where two familiar faders control expression and timbral/dynamic volume. The etched reticle can function with red dot reticle or greed dot reticle or without illumination, accounting for almost all light conditions. During the Chinese Civil War, 80 Squadron's main duty was to defend Hong Kong from perceived Communist threats. The streamlined, semi-monocoque, duralumin-skinned fuselage featured a number of compound, vertical curves built up from a skeleton of 19 formers, also known as frames, starting from frame number one, immediately behind the propeller unit, to the tail unit attachment frame. [134], Although R. J. Mitchell is justifiably known as the engineer who designed the Spitfire, his premature death in 1937 meant that all development after that date was undertaken by a team led by his chief draughtsman, Joe Smith, who became Supermarine's chief designer on Mitchell's death. This matter was almost conclusively answered in 1985 by aviation author Alfred Price, who received an account sheet with a handwritten note updating a line from "Not yet flown" to "Flew 5 Mar 36". In the continual programme of updating and improving the Spitfire, the next most significant development was the Mark V, and with a production run of nearly 6,500, this was the most common type ever produced. [6], The Type 224 was a big disappointment to Mitchell and his design team, who immediately embarked on a series of "cleaned-up" designs, using their experience with the Schneider Trophy seaplanes as a starting point. This wing was tested on a modified F Mk 21, also called the F Mk 23, (sometimes referred to as "Valiant" rather than "Spitfire"). Zachary. In April 1944, the same aircraft suffered engine failure in another dive while being flown by Squadron Leader Anthony F. Martindale, Royal Air Force Volunteer Reserve, when the propeller and reduction gear broke off. The essence of aircraft design is compromise, and an improvement at one end of the performance envelope is rarely achieved without a deterioration somewhere else. In 1941 and 1942, PRU Spitfires provided the first photographs of the Freya and Wrzburg radar systems, and in 1943, helped confirm that the Germans were building the V1 and V2 Vergeltungswaffen ("vengeance weapons") rockets by photographing Peenemnde, on the Baltic Sea coast of Germany. After repair, it was used for training until August 1944, when it became one of several Battle of Britain aircraft veterans that were allocated to the Air Historical Branch for future museum preservation. [22] A new and better-shaped, two-bladed, wooden propeller allowed the Spitfire to reach 348mph (557km/h) in level flight in mid-May, when Summers flew K5054 to RAF Martlesham Heath and handed the aircraft over to Squadron Leader Anderson of the Aeroplane & Armament Experimental Establishment (A&AEE). R J Mitchell, the Supermarine Spitfires designer, learnt his trade during WWI. Owner Kermit Weeks insisted that the aircraft be restored as closely as possible to its original condition. [82], The light alloy split flaps at the trailing edge of the wing were also pneumatically operated via a finger lever on the instrument panel. 155 Other Spitfire Audio Products; 30 Product Suggestions; 21 Third Party products; 440 Spitfire Audio Academy; 124 Composition and Production; 43 Competitions; Wingspan - 11.23m. The Spitfire also served in the Pacific Theatre, meeting the Japanese Mitsubishi A6M Zero. Four towns and their satellite airfields were chosen to be the focal points for these workshops:[40] Southampton's Eastleigh Airport; Salisbury and the High Post and Chattis Hill[43][nb 5] aerodromes; Trowbridge and RAF Keevil;[44] and Reading's Henley and Aldermaston aerodromes. 1113, 17, 42, 64, 6768, 92. [144], The Seafire II was able to outperform the A6M5 Zero at low altitudes when the two types were tested against each other during wartime mock combat exercises. Spitfire units had a lower attrition rate and a higher victory-to-loss ratio than those flying Hurricanes, probably because of the Spitfire's higher performance. The original wing design had a theoretical aileron reversal speed of 580mph (930km/h),[87] which was somewhat lower than that of some contemporary fighters. [138], Supermarine developed a two-seat variant, known as the T Mk VIII, to be used for training, but none were ordered, and only one example was ever constructed (identified as N32/G-AIDN by Supermarine). 131.". Replacing the fabric covering with light alloy dramatically improved the ailerons at high speed. [108] "Paddy" Finucane (2832 e/a) scored all his successes in the fighter before disappearing over the English Channel in July 1942. Spitfires fitted with two Hispano cannons and four Browning machine guns, the first squadron fully equipped with these was 19 Squadron in June 1940. [140], In the postwar era, the idea was revived by Supermarine and a number of two-seat Spitfires were built by converting old Mk IX airframes with a second "raised" cockpit featuring a bubble canopy. Engine - Merlin III. The first bombing raid, which missed the factories, came on 23 August 1940. [151], Operation Firedog during the Malayan Emergency saw the Spitfire fly over 1,800 operational sorties against the Malayan Communists. 2. These laminar-flow airfoils were the Supermarine 371-I used at the root and the 371-II used at the tip. Further improvements were introduced throughout the Merlin series, with Bendix-manufactured pressure carburettors, designed to allow fuel to flow during all flight attitudes, introduced in 1942. A "Spitfire Lane" can be found on the road between Salisbury and. [141][nb 13], The Seafire, a name derived from sea, and Spitfire, was a naval version of the Spitfire specially adapted for operation from aircraft carriers. The sleekly elegant Supermarine Spitfire is the iconic British fighter of World War II, the plane that kept the formerly unstoppable German air force at bay in the Battle of Britain. Douglas Bader (20 e/a) and "Bob" Tuck (27 e/a) flew Spitfires and Hurricanes during the major air battles of 1940. And thanks to constant upgrades, the Spitfire remained a top-performing frontline fighter through the end of the war. The 224 was an open-cockpit monoplane with bulky gull wings and a large, fixed, spatted undercarriage powered by the 600-horsepower (450kW), evaporatively cooled Rolls-Royce Goshawk engine. Personally, I never cleared a Spitfire unless I had carried out a few aerobatic tests to determine how good or bad she was. 56. [140] The only unofficial two-seat conversions that were fitted with dual-controls were a few Russian lend/lease Mk IX aircraft. A Spitfire on an AD troop lets you deploy in a prime position to lay down some serious firepower. The most expensive components were the hand-fabricated and finished fuselage at roughly 2,500, then the Rolls-Royce Merlin engine at 2,000, followed by the wings at 1,800 a pair, guns and undercarriage, both at 800 each, and the propeller at 350. [55], A wing feature that contributed greatly to its success was an innovative spar boom design, made up of five square tubes that fitted into each other. [102] A variant on the Spitfire design with four 20mm Oerlikon cannon had been tendered to specification F37/35, but the order for prototypes had gone to the Westland Whirlwind in January 1939.[103]. A Spitfire model ML407 was purchased by Carolyn Grace and her husband Nick in 1979. He was conscious of the fragility of the early planes, and always considered pilot safety in his designs. Another PR Mk 19, PS853, which is now owned by Rolls-Royce, was on gate-guard duties at Binbrook, having been retired from the Battle of Britain Memorial Flight (BBMF) one year before. $999.00 Add to cart Here, Flight Lieutenant Humphrey Edwardes-Jones took over the prototype for the RAF. Spitfire Audio Hammers: Performance and verdict. Gerdessen, Frederik. Limited time Save 30% on string libraries. Ten of these TR9 variants were then sold to the Indian Air Force along with six to the Irish Air Corps, three to the Royal Netherlands Air Force and one for the Royal Egyptian Air Force. Allow cookies Technical. These covered the Spitfire in development from the Merlin to Griffon engines, the high-speed photo-reconnaissance variants and the different wing configurations. [12], On 5 March 1936,[13][nb 1] the prototype (K5054), fitted with a fine-pitch propeller to give more power for takeoff, took off on its first flight from Eastleigh Aerodrome (later Southampton Airport). The B wing was designed to accommodate the newly accepted Hispano-Suiza 20mm cannon, so each wing had one cannon and two .303 machine guns. [58], A combination of 14 longitudinal stringers and four main longerons attached to the frames helped form a light, but rigid structure to which sheets of alclad stressed skinning were attached. "Supermarine Spitfire (Griffon-engined variants and Seafire)". A person with a fiery temper, someone easily provoked to anger. The ellipse was skewed so that the centre of pressure, which occurs at the quarter-chord position, aligned with the main spar, preventing the wings from twisting. [30] A production aircraft cost about 9,500. The Spitfire also served on the Eastern Front with the Soviet Air Force (VVS). All rights reserved. (in Italian), Gunston, Bill et al. Price 1996, pp. The Spitfire's stressed-skin construction required precision engineering skills and techniques that were beyond the capabilities of the local labour force, and some time was required to retrain them. The same day P7666 was delivered to the squadron, 23 November 1940, Finlay destroyed a Bf 109 on his first operational sortie in the aircraft. Later, a new fuselage was designed, with the new fighter becoming the Supermarine Spiteful. [28], The first production Spitfire came off the assembly line in mid-1938[1] and was flown by Jeffrey Quill on 15 May 1938, almost 24 months after the initial order. In January 1940, P/O George Proudman flew this prototype in combat, but the starboard gun stopped after firing a single round, while the port gun fired 30 rounds before seizing.
