The full remedy was to use the Bendix-Stromberg pressure carburettor , which allowed more precise metering of the amount of fuel used by the engine and prevented fuel starvation. This new carburettor was used from the Merlin 66 series and on all Griffon engines. In these engines the carburettor injected fuel at 5 psi through a nozzle direct into the supercharger and the compressed air-fuel mixture was then directed to the cylinders. The final development was the SU injection carburettor, that injected fuel into the supercharger using a fuel pump driven as a function of crankshaft speed and engine pressures; although this was fitted to the series Merlins, which were not used in production Spitfires, it was used in the Griffon 60 and 80 series. The British measured boost pressure as lbs. Typically "absolute pressure" is indicated in inches of mercury because "absolute pressure" is dependent on multiple atmospheric influences and can be used to indicate and measure "vacuum", or pressure below atmospheric pressure, as well. Subjecting water to pressures above or below atmospheric pressure raise or lowers its triple points and causes it to boil at "standard" temperature if subjected to near one atmosphere of "vacuum" Such vacuum levels are common in spark-ignition internal-combustion engine intake manifolds at "idle" speeds and loads rendering water useless as a liquid-column manometer test medium. Even at lower vacuum levels it evaporates to readily and quickly to provide consistent vacuum readings. Since atmospheric pressure is a given and a "constant" a "boost gauge" or manometer calibrated to indicate 0 psi or in. Absolute pressure requires subtracting And "vacuum" is used to properly tune carburetors or fuel injection systems and ignition timing as well as determine engine condition and diagnose engine malfunctions, mis- adjustments and failures. Such departures are generally far too small to make inflated "absolute" vacuum pressure use practical or even possible. Therefore, "gauge pressures" independent of atmospheric pressure-influenced "absolute" pressures are preferred for monitoring, tuning and diagnosing engine operation and performance when mechanical fuel systems and gauges are in use. Outside of MAP sensor data "gauge pressure" is typically used for engine system vacuum and pressure measurement. Which is why "boost gauges" almost universally indicate 0 psi at idle speed and load. In an attempt to boost the performance of the Spitfire Mk1 in May , RAe scientists including Hayne Constant developed a 'propulsive duct'. This was in essence a simple ram jet, fed by petrol, utilising the Meredith effect. Bench tests showed that the increase in speed was not significant and the device was not flight tested. In the idea was reconsidered as a counter to the threat of the V1. Aircraft such as the Hawker Tempest and Gloster Meteor were not widely available and the Spitfire would only be able to intercept in a diving attack. Baxter and C. Smith at Farnborough reviewed the work and concluded that it was practical but problems with drag and pressure loss were encountered and the V1 had been beaten before they were solved. Due to the many differences in production Spitfires, performance could vary widely, even between aircraft with the same Mark number. Factors such as weight, external fittings, airframe and engine condition, among others, influenced how an aircraft performed. For example, even relatively minor damage on the wing leading edges could drastically reduce top speed. From Wikipedia, the free encyclopedia.

By , the career of the Spitfire is well underway and the RAF has a powerful aircraft with the Mark V that exceeds all expectations. Yet the RAF is already preparing for its successor and new versions are being considered to keep the fighter a step ahead of the opponent. Manufactured until the end of the war and used on all fronts, this aircraft became the standard fighter of the RAF and was widely exported, particularly after the end of hostilities. IX equipped with an engine produced by Packard in the United States. Supermarine Spitfire V Vol. 2 Operation Firedog during the Malayan Emergency saw the Spitfire fly over 1, operational sorties against the Malayan Communists. To mark the special occasion, ground crewmen had painted 'The Last' on the aircraft's nose. This was also the last known flight of a piston-engined fighter in the RAF. At the time, British Commonwealth forces were involved in possible action against Indonesia over Malaya and Nicholls decided to develop tactics to fight the Indonesian Air Force P Mustang, a fighter that had a similar performance to the PR Mk It had been maintained in running condition by ground crews at Binbrook, and after a short time was participating in the trials. It was concluded that the most effective and safest way for a modern jet-engined fighter to attack a piston-engined fighter was to engage full afterburner at an altitude lower than the Spitfire, and circle behind it to perform a hit-and-run attack, contrary to all established fighter-on-fighter doctrine at that time. Stuka dive bomber. This aircraft was the th built and first flew in April It flew operationally with No. After repair, it was used for training until August , when it became one of several Battle of Britain aircraft veterans that were allocated to the Air Historical Branch for future museum preservation. What may be the most originally restored Spitfire in the world is maintained at Fantasy of Flight in Polk City, Florida. Owner Kermit Weeks insisted that the aircraft be restored as closely as possible to its original condition. Machine guns, cannon, gun sight and original working radios are all installed. It is one of only four flying MK 1 Spitfires in the world. After hostilities ceased in Asia in , a number of Spitfire Mk. XIVs were reportedly buried, after being greased, tarred and prepared for long-term storage, in crates in Burma. Excavations carried out at Yangon International Airport formerly RAF Mingaladon in early failed to locate any of the rumoured aircraft, [] [] and the team reported that they found no evidence that Spitfires were shipped there in crates or buried. British company Historic Flying Limited has either restored or built from scratch a significant proportion of the Spitfires that are now airworthy. Several other manufacturers have produced replica Spitfires, either as complete aircraft or as kits for self-building. Their Supermarine Aircraft Spitfire is supplied in kit form and is the only all- aluminium reproduction Spitfire in production. Greenwood Military Aviation Museum is also home to a replica non-flying Spitfire. During and after the Battle of Britain, the Spitfire became a symbol of British resistance: for example, Lord Beaverbrook's "Spitfire Fund" of was one campaign which drew widespread public attention to the Spitfire. The Spitfire continues to be highly popular at airshows, on airfields and in museums worldwide, and holds an important place in the memories of many people, especially the few still living who flew the Spitfire in combat. Numerous films and documentaries featuring the Spitfire are still being produced, some of which are listed in this section. The Spitfire's performance improved greatly as WWII progressed, for more information see Supermarine Spitfire variants: specifications, performance and armament.

Aerodynamically it was the best for our purpose because the induced drag caused in producing lift, was lowest when this shape was used: the ellipse was To reduce drag we wanted the lowest possible thickness-to-chord, consistent with the necessary strength. But near the root the wing had to be thick enough to accommodate the retracted undercarriages and the guns Mitchell was an intensely practical man The ellipse was simply the shape that allowed us the thinnest possible wing with room inside to carry the necessary structure and the things we wanted to cram in. And it looked nice. Main article: Supermarine Spitfire operational history. That any operational aircraft off the production line, cannons sprouting from its wings and warts and all, could readily be controlled at this speed when the early jet aircraft such as Meteors , Vampires , Ps , etc, could not, was certainly extraordinary.
