One test of manoeuvrability was to throw her into a flick-roll and see how many times she rolled. The second cockpit of this aircraft has been lowered and is now below the front cockpit. Windscreen plastic had been replaced by armoured glass, armour plate was fitted at the rear of the engine bulkhead, a power-operated pump was installed to operate the undercarriage, and the tail-skid had been replaced by a wheel. A Spitfire on an AD troop lets you deploy in a prime position to lay down some serious firepower. The first of the production Spitfires with these engines was the Mark XII with the Griffon III or IV, followed by the Mark XIV with the 2050hp Griffon 65, driving a five-blade Rotol propeller. Due to the high altitudes necessary for these dives, a fully feathering Rotol propeller was fitted to prevent overspeeding. Air combat was also felt to take place at relatively low speeds and high-speed manoeuvring would be physically impossible. The early Mark Is had a service ceiling of 31,900ft, and at 30,000ft could reach a speed of 315mph. Military archaeologist Keith Robinson celebrates the iconic design. Download the Spitfire Audio App to start your Spitfire journey. [6] This led to the Type 300, with retractable undercarriage and a wingspan reduced by 6ft (1.8m). [52], In the mid-1930s, aviation design teams worldwide began developing a new generation of fighter aircraft. 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. [108] "Paddy" Finucane (2832 e/a) scored all his successes in the fighter before disappearing over the English Channel in July 1942. Recovered from the beach in September 1980, it was stored at the Musee del'Air, Vannes, France, until 1996. There was no D wing, but an E wing was created, which carried a 20mm cannon and a .50in machine gun. 2019 iMac 21,5", i5, 16 Go ram, 1T SSD. Price 1996, pp. Alternatively, you can click here to read our recent article on a barn [], Military History Matters magazine February/March 2023 is out now. What he meant was that he wanted nothing touched, especially the control settings, until he had consulted with Mitchell and the design team and suggested some improvements. [83] Only two positions were available; fully up or fully down (85). This page was last edited on 13 January 2023, at 17:37. [nb 6] Quill devised the standard testing procedures, which with variations for specific aircraft designs operated from 1938. Its maximum speed was 362mph at 18,500ft. Widely regarded throughout its long and well-developed life as a masterpiece of the avionic arts; a graceful-yet-deadly dogfighter and a peerlessly beautiful design. Imperial War Museum Duxford, Cambridgeshire, is home to the largest collection of Spitfires, with 15-20 airworthy and static examples on site most weeks throughout the year. You will be impressed. They were placed four to a wing, a novel concept at the time, and designed to fire outside the circle of the propeller, doing away with the need for the interrupter gear of earlier aircraft. Spitfire Audio app. 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. Owner Kermit Weeks insisted that the aircraft be restored as closely as possible to its original condition. As Jeffrey Quill noted: "If Mitchell was born to design the Spitfire, Joe Smith was born to defend and develop it. All rights reserved. [4] It made its first flight in February 1934. A tail skid completed the technical arrangements for take-off and landing. Early, Merlin-powered Spitfires were not the only aircraft to suffer from this problem, as other prewar aeroplanes also used carburettors containing a float chamber. The Spitfire Audio App, previously known as the "Spitfire Audio Library Manager" is the downloader application for our libraries. Douglas Bader (20 e/a) and "Bob" Tuck (27 e/a) flew Spitfires and Hurricanes during the major air battles of 1940. Unfortunately, Mitchell died of cancer in June 1937. Cookies. The Allies achieved air superiority when the Mk VIII version was introduced to the theatre, replacing the earlier Mk V. In one memorable encounter, New Zealand ace Alan Peart fought a solo dogfight against two dozen Japanese aircraft attacking the Broadway airstrip, shooting down one. [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. $19.99 + $6.00 shipping . The show had been spectacular, even in spite of the rock hitting his goggles. 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. In spite of promises that the factory would be producing 60 per week starting in April, by May 1940, Castle Bromwich had not yet built its first Spitfire. Between 1940 and 1946, Henshaw flew a total of 2,360 Spitfires and Seafires, more than 10% of total production.[47][48]. He was conscious of the fragility of the early planes, and always considered pilot safety in his designs. He organised a conference, with Air Commodore Tedder in the chair, on 19 July 1934. Henshaw wrote about flight testing Spitfires: After a thorough preflight check, I would take off, and once at circuit height, I would trim the aircraft and try to get her to fly straight and level with hands off the stick Once the trim was satisfactory, I would take the Spitfire up in a full-throttle climb at 2,850rpm to the rated altitude of one or both supercharger blowers. Price 1996, pp. There was little difference between the two marks, the main one being that the Mark II Spitfires were fitted with the Merlin XII engine, rated at 1150hp. 155 Other Spitfire Audio Products; 30 Product Suggestions; 21 Third Party products; 440 Spitfire Audio Academy; 124 Composition and Production; 43 Competitions; The first bombing raid, which missed the factories, came on 23 August 1940. [49][50], When the last Spitfire rolled out in February 1948,[51] a total of 20,351 examples of all variants had been built, including two-seat trainers, with some Spitfires remaining in service well into the 1950s. [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. Keith held various appointments with the RAF dealing with designing, development and technical policy of armament equipment. [139] Currently several of the trainers are known to exist, including both the T Mk VIII, a T Mk IX based in the US, and the "Grace Spitfire" ML407, a veteran flown operationally by 485(NZ) Squadron in 1944. Red fabric patches were doped over the gun ports to protect the guns from cold, dirt, and moisture until they were fired. 131.". Fifty Mark IBs were manufactured, but there were problems with feed to the cannon. The Mark II had better protection for the pilot as well, with increased armour behind the pilots seat to protect his head. Personally, I never cleared a Spitfire unless I had carried out a few aerobatic tests to determine how good or bad she was. Download the Spitfire Audio App to start your Spitfire journey. In fact, such was the Spitfire's . 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. While this prevented overheating of the cordite used in British ammunition, it allowed cold air to flow through the barrel unhindered. Mitchell, however, was already working on a much superior design, the Type 300, and went into collaboration with Rolls-Royce, who were, themselves, working on a new engine, which would eventually become known as the Merlin. Edwardes-Jones' report was positive; his only request was that the Spitfire be equipped with an undercarriage position indicator. [71], Another wing feature was its washout. . In 1936, this informal request for major manufacturing facilities was replaced by a formal scheme, known as the shadow factory plan, to boost British aircraft production capacity under the leadership of Herbert Austin. By the beginning of 1939, the factory's original estimated cost of 2,000,000 had more than doubled,[33] and even as the first Spitfires were being built in June 1940, the factory was still incomplete, and suffering from personnel problems. 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. The plane was originally fitted with a two blade, fixed-pitch wooden propeller and aMerlin C engine. Suspension was provided by oleo legs, which were telescopically sprung on oil and air. [73] This washout was first featured in the wing of the Type 224, and became a consistent feature in subsequent designs leading to the Spitfire. Machine guns, cannon, gun sight and original working radios are all installed. I really don't like gushing, but the sound of the legato seems so much more believable than anything else in my colleciton - spitfire OR other companies. The Professional edition includes four additional microphone positions and three CPU-friendly stereo mixes by award-winning engineer Jake Jackson, giving you a hugely diverse range of string sounds. [102] In November 1938, tests against armoured and unarmoured targets had already indicated that the introduction of a weapon with a calibre of at least 20mm was urgently needed. First flown in March 1936, it was designed as a short- range defensive fighter for rapid interception of raiding fighters and bombers. These range in scale from 60% scale to full-size, and most use wooden construction rather than the original all-metal monocoque design. [152], In late 1962, Air Marshal Sir John Nicholls instigated a trial when he flew Spitfire PM631, a PR Mk 19 in the custody of the Battle of Britain Memorial Flight, against an English Electric Lightning F 3 (a supersonic jet-engined interceptor) in mock combat at RAF Binbrook. The Seafire was an aircraft carrier-based adaptation of the Spitfire, used in the Fleet Air Arm from 1942 until the mid-1950s. March 2021 edited March 2021. They were manufactured mostly in the B and C versions. A fibreglass replica in the colours of a Polish squadron leader based at the station during the Second World War is on display at, A replica Spitfire is on display on the Thornaby Road roundabout near the school named after Sir Douglas Bader who flew a Spitfire in the Second World War. These include the Jurca Spit from France, and those manufactured by Tally Ho Enterprises in Canada. "UK Space Conference 2008: Test Pilot Discussion. "World War II Fighter Aerodynamics. Donald O. Finlay, the commanding officer of 41 Squadron from September 1940 to August 1941, who adopted the aircraft as his personal mount. Mitchell continued to refine the design until his death in 1937, whereupon his colleague Joseph Smith took over as chief designer, overseeing the Spitfire's development through many variants. 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. Arson Business is all we know. Its maximum cruising speed, though, was 210mph at 20,000ft, and at economical speed its range was 575 miles. "Technical Note: A CFD Evaluation of Three Prominent World War II Fighter Aircraft. Look for a new glow-in-the-dark short and long sleeve T and pullover Hoodie as well. At the end of the trials, RAF pilots found that Firestreak infra-red guided missiles had trouble acquiring the Spitfire due to a low exhaust temperature, and decided that the twin ADEN 30mm (1.2in) cannons were the only weapons suited to the task, which was complicated by the tight turning circle of the Spitfire, and the Lightning's proclivity for over-running the Spitfire. Over the next month, other raids were mounted, until, on 26 September 1940, both factories were destroyed,[40] with 92 people killed and a large number injured. The installer can be found here. Many of Supermarine's records from this era were destroyed during a bombing raid in 1940, and none of the surviving documents seemed to pin this down. The Merlin 46 and Merlin 50 were also used in the VB. A team of original Supermarine designers worked with Aerofab Restorations of Andover for 10 years to create the facsimile. Most of the casualties were experienced aircraft-production workers.[41]. He eventually regained control somewhere below 3,000ft (910m) and landed safely with no discernible damage to his aircraft. The airflow through the main radiator was controlled by pneumatic exit flaps. You always have a positive effect on me with your words and actions. Soarin' trotted into the VIP section after the show. Price, Alfred. Mitchell developed the Spitfire's distinctive elliptical wing with innovative sunken rivets (designed by Beverley Shenstone) to have the thinnest possible cross-section, achieving a potential top speed greater than that of several contemporary fighter aircraft, including the Hawker Hurricane. [100] At that meeting, scientific officer Captain F. W. "Gunner" Hill presented charts based on his calculations showing that future fighters must carry no less than eight machine-guns, each of which must be capable of firing 1,000 shots a minute. Beginning in late 1943, high-speed diving trials were undertaken at Farnborough to investigate the handling characteristics of aircraft travelling at speeds near the sound barrier (i.e., the onset of compressibility effects). [150] With these aircraft, 80 Squadron continued its patrol and reconnaissance duties from Wunstorf in Germany as part of the occupation forces, until it relocated to Kai Tak Airport, Hong Kong, in July 1949. It is also rumoured that there is anywhere from 5 to 10 restoration projects also progressing on site between The Fighter Collection and the Aircraft Restoration Company. Pre War Spitfire 'Customers' By 1938 there was a queue of countries clamouring to add Spitfires to their frontline arsenals. As the wing thinned out along its span, the tubes were progressively cut away in a similar fashion to a leaf spring; two of these booms were linked together by an alloy web, creating a lightweight and very strong main spar. The etched reticle can function with red dot reticle or greed dot reticle or without illumination, accounting for almost all light conditions. He oversaw a group of 10 to 12 pilots responsible for testing all developmental and production Spitfires built by the company in the Southampton area. 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". These were basically Colt .30s manufactured under licence but re-chambered to take the British rimmed cartridges. Initially, the Spitfire was armed with eight Colt-Browning machine guns chambered for .303 ammunition. To its elliptical wings and all-metal monocoque body, where the skin is part of the planes structure rather than just a covering, had been added the bulged, or blister-shaped, cockpit, thereby completing the Spitfires classic profile. [81] The wing tips used spruce formers for most of the internal structure with a light alloy skin attached using brass screws. He continued to work despite increasing pain, tweaking the design up to the moment of his death earning himself the posthumous sobriquet the first of the few from the makers of his 1942 film biography. [56], The Spitfire's airframe was complex. [29] The final cost of the first 310 aircraft, after delays and increased programme costs, came to 1,870,242 or 1,533 more per aircraft than originally estimated. Later models further improved upon this. Williams, Anthony G. and Dr. Emmanuel Gustin. [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). His masterpiece, the Spitfire, proved to be not only a beautiful plane much loved by its pilots, but also a robust and adaptable design. During the Battle of Britain, the Luftwaffe made concerted efforts to destroy the main manufacturing plants at Woolston and Itchen, near Southampton. [163], What may be the most originally restored Spitfire in the world is maintained at Fantasy of Flight in Polk City, Florida. 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. Some with the Universal wing were given four cannons and could carry one 500lb bomb or two 250lb bombs. 17, 3537, 41, 62, 66, 91. Data from Spitfire: The History and Jane's Fighting Aircraft of World War II. 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. [124] Spitfire MKVIIIs took part in the last battle of World War II involving the Western allies in Burma, in the ground attack role, helping defeat a Japanese break-out attempt. On 3 June 1936, the Air Ministry placed an order for 310 aircraft, at a cost of 1,395,000. "Spitfires with Sea Legs, Part two.". [57] Behind the bulkhead were five U-shaped half-frames which accommodated the fuel tanks and cockpit. This aircraft was the 155th built and first flew in April 1939. In any case, it would have been simply asking for trouble to have copied a wing shape from an aircraft designed for an entirely different purpose. The Spitfires ceiling was also raised by some 2,000ft. The Merlin Mark II engines were giving way to the Mark III with its improved airscrew shaft, and the two-blade wooden propeller had been replaced by the De Havilland three-blade metal, two-pitch propeller, significantly enhancing performance, particularly in the climb. [94] Sir Stanley Hooker explained that the carburettor was adopted because it "increased the performance of the supercharger and thereby increased the power of the engine". [40] To this end, the British government requisitioned the likes of Vincent's Garage in Station Square, Reading, which later specialised in manufacturing Spitfire fuselages, and Anna Valley Motors, Salisbury,[42] which was to become the sole producer of the wing leading-edge fuel tanks for photo-reconnaissance Spitfires, as well as producing other components.
