This Spitfire has the "cropped" Merlin 45 series engine and the "clipped" wings. The British Supermarine Spitfire was one of the most popular fighter aircraft of the Second World War . The basic airframe proved to be extremely adaptable, capable of taking far more powerful engines and far greater loads than its original role as a short-range ...
The later Spitfire Mk 26 uses the Mk 25 wings with the fuselage increased to 80% scale to provide room for a passenger seat in tandem behind the pilot. The Mk 26B has a 90% scale fuselage. The Spitfire kit has the same power-to-weight ratio as the original. [6] The aircraft was reviewed by the Australian Ultralight Federation in 2001.
The modified engine was designated the "TMO" and the modified exhaust system was supplied as kit that could be installed on existing engines either by the operator or by Rolls-Royce. [ 24 ] Power ratings for the civil Merlin 600, 620, and 621-series was 1,160 hp (870 kW) continuous cruising at 23,500 feet (7,200 m), and 1,725 hp (1,286 kW) for ...
These remarkable increases in performance arose chiefly from the introduction of the Rolls-Royce Griffon engine in place of the famous Merlin of earlier variants. Rated at 2,050 hp (1,530 kW), the 12-cylinder Vee liquid-cooled Griffon 61 engine had a two-stage supercharger, giving the Spitfire the exceptional performance at high altitude that ...
The performance increase was described by Jeffrey Quill as a "quantum leap" over that of the Mk Vb and another Spitfire airframe, R6700 was modified to take the new engine. Although design work on the Mk VII and VIII series was under way, these would take over a year to get into production and a counter to the Fw 190 was urgently needed.
Their Supermarine Aircraft Spitfire is supplied in kit form and is the only all-aluminium reproduction Spitfire in production. [193] The Isaacs Spitfire (1975) [ 194 ] and the Time Warp Spitfire Mk V (1996) are homebuilt 60% scale replicas, and Bob DeFord of Prescott, Arizona built and flies a 100% scale replica.
Spitfire Mk Vb BM597 of Duxford's Historic Aircraft Collection in the markings of 317 (Polish) "Wileński" Squadron. Supermarine Spitfire variants powered by early model Rolls-Royce Merlin engines mostly utilised single-speed, single-stage superchargers.
The Spitfire was much slower at such a low level; the prototype was only capable of 290 mph (470 km/h) at this height. [1] Consequently, a record-breaking machine would have to be extensively modified. Rolls-Royce began work on a sprint version of the Spitfire's Merlin engine, to run on a special fuel mix. [1]
