	WW2 Warbirds: the Hawker Tempest - Frans Bonné
		But not only the Napier Sabre IV was planned as the powerplant for the Tempest, also the Bristol Centaurus (for the Mk II), Rolls Royce Griffon (Mk II and Mk IV) and Napier Sabre V (Mk VI) were planned to power one of the respective versions.
		So when the development of the Napier Sabre IV was discontinued, the Tempest Mk I was dropped but other versions were still ordered.
		The inlets for the oil cooler and carburetor were moved from the nose to the wing roots to accomodate a larger radiator.

	THE NOMAD PROPOSAL (Site not responding. Last check: 2007-11-04)
		The famous aero-engine firm of D. Napier and Sons of Acton, West London, though often thought reluctant to move with the times, had in the 1920s experimented with exhaust-driven superchargers and in the 1930s dabbled in diesels, but with little success.
		Napier was, however, well aware that the General Electric Company of America had developed heat-resistant steels that enabled turbo-superchargers to be in-stalled in operational aircraft such as the P-38 Lightning, P-47 Thunderbolt and B-29 Superfortress, and that other firms, notably Junkers, had steadily improved the aircraft diesel.
		Napier was impressed by his arguments and using pre-war experience with the Culverin and Cutlass (valveless two-stroke diesels) and more recent work on the Sabre (horizontally opposed cranks and centrifugal compressor) designed a 24-cylinder H-type engine of 75 litres capacity.

	The Napier Sabre Engine
		Napier had developed this type of engine since before 1935 in the form of its Napier Rapier engine.
		What was significantly different in the Sabre was that it used sleeve valves instead of the more familiar poppet valves.
		While Napier sleeves were distorting after only 20 hours, Bristol sleeves lasted for 120 hours without any sign of real wear.

	Napier Sabre - Wikipedia, the free encyclopedia
		The Sabre was a 24-cylinder sleeve valve piston aircraft engine designed by Major Frank Halford and built by Napier and Son during WWII.
		Halford's office was next to Ricardo's in London, and while Ricardo started work with Bristol Engines on a whole line of sleeve-valve designs, Halford started work with Napier, using the Dagger as the basis of what would become the most powerful engine in the world.
		The first Sabre engines were ready for testing in January 1938, although at a severely limited 1,350 hp (1,000 kW).

	History 1
		D. Napier and Son is an under-rated company which has not only manufactured superb products bringing credit to this country, but has also been responsible for the training of engineers to carry its standards of excellence to be used by other industries.
		Napiers realized the fundamental features for an aero-engine, low weight, smallest possible frontal area and maximum power, this generally means squeezing many cylinders into a small volume.
		The ‘Sabre’ was also a 24-cylinder ‘H’ form engine but it was horizontally opposed, not vertical as were the Rapier and Dagger, and water-cooled, not air-cooled.

	Stof's Tempest Page
		Another problem of the Typhoon was the lack of reliability of its Napier Sabre engine, so it was decided to power the Tempest with the Bristol Centaurus, a huge 18-cylinder radial engine with twice the displacement of a Rolls-Royce Merlin.
		The Tempest Mk.I should have been powered by the Napier Sabre IV, but this version of the engine was delayed because of technical problems and the Tempest Mk.I was cancelled.

	The Hawker Typhoon, Tempest, & Sea Fury
		The early "Sabre IIA", rated at 1,625 kW (2,180 HP), led to the "Sabre IIB" with 1,640 kW (2,200 HP) and the "Sabre IIC" with 1,685 kW (2,260 HP).
		Napier experimented with at least one Typhoon fitted with a "ring" radiator that gave it the appearance of a radial-engine fighter, but though the fit was technically very successful and noticeably improved performance, the Air Ministry did not want to disrupt production and nothing came of it.
		The Centaurus was generally regarded as superior to the Sabre, particularly in terms of reliability, and the Centaurus engine and Tempest airframe proved an excellent match.

	Hawker Typhoon and Tempest history
		Alternative installations of the Sabre engine were designed for these prototypes; the first (HM595) had a Sabre II and a front radiator similar to that of the standard Typhoon, while the second (HM599) had a Sabre IV engine and wing leading-edge radiators.
		The 820-mile range of the Tempest V in clean condition was an appreciable improvement over that of the Typhoon, and was due not only to the small additional quantity of fuel carried but to the aerodynamic refinement of the later machine which permitted a higher cruising speed for the same power.
		Sabre VA engine and, except in having small intake ducts in the wing roots, was outwardly indistinguishable from the Tempest V. By and large, both the Typhoon and Tempest escaped the fate of so many aeroplanes of being used as test-beds for a variety of experiments.

		The Sabre represented the ultimate in piston engine technology, not only in the 1930s when it was conceived, but even by today ´s standards.
		Several of the improvements incorporated into the Sabre V were relocating the outboard, overhung supercharger clutches to behind the crankcase, thus reverting to conventional in-line configuration.
		The Sabre VII was similar to the V; the primary difference was the use of ADI and the strengthening of the internal components.

		Moreover, Napier made a serious effort to cure the problems, and while never being as reliable as the Merlin (the Sabre’s complexity made it more likely to suffer a mechanical failure), it was developed to a reasonable level of reliability for a combat aircraft powerplant.
		The Sabre was not yet debugged sufficiently and the airframe weakness was not yet properly cured.
		The Sabre IV for the Tempest Mk.I and the Sabre II for the Tempest Mk.V. Additional prototypes were built utilizing the Bristol Centaurus radial engine (the data from the Tornado was finally reaping some benefit), and one to be fitted with the Rolls Royce Griffon 61.

		This was to be a massive plane designed around the equally massive Napier Sabre engine.
		The work proved useful when Hawker received specification F.18/37 in January 1938 from the Air Ministry, which asked for a fighter based around either the Napier Sabre or the Rolls-Royce Vulture engine.
		The basic design of both continued the Hawker tradition of using 'older' construction techniques; the front fuselage was welded steel just like the Hurricane, and the design used a massive 40 foot (12 m) wing that was much thicker than those on designs like the Spitfire.

		Later the Napier workers were spared at least some of the fear caused by every air raid- thanks to their own hard work.
		It was this proud record which helped Napier employees know that the work they were doing was just as vital as the servicemen in the front line.

		Napiers expanded into marine engines as well, their 1905 boat Napier II setting the world water speed record for a mile at almost 30 knots (56 km/h).
		Napier developed a marine engine from the Lion aero engine, the petrol-driven Sea Lion, which could deliver 500 hp and were used in the "Whaleback" Air Sea Rescue Launches.
		During the war (1944) Napier were asked by the Royal Navy to supply a diesel engine for use in their patrol boats, but the Culverin's 720 hp (537 kW) was not nearly enough for their needs.

	The Hawker Typhoon and Tempest - Great Britain
		Structurally both types were similar: the wings were all-metal, the front fuselage was of steel tubing, and the aft section consisted of a stressed-skin, flush-riveted monocoque--the first Hawker designs to employ this form of construction.
		Alternative installations of the Sabre engine were designed for these prototypes; the first (HM595) had a Sabre II and a front radiator similar to that of the standard Typhoon, while the second (HM599) had a Sabre IV engine and wing leading-edge radiators.

		David Napier and Sons Ltd of Acton, West London, were a long established manufacturer of innovative piston engines, who's products included the powerful Halford designed, Napier Sabre which powered the Hawker Typhoon and Tempest aircraft.
		Napier were not as quick to turn their attentions to jet power as some of their contemporaries and their products were not as advanced as some of their piston engines.
		In 1960 Napier Aero Engines was formed as a separate entity from the companies other activities and in 1962 was incorporated into Rolls-Royce.

		It was to be powered by an advanced in-line piston engine, the Napier Sabre, which promised to deliver 2,000hp - twice the power of the Hurricane.
		First flown in early 1940, development of the typhoon was delayed by the Battle of Britain and problems with the 24-cylinder, twin-crank shaft, sleeve-valved Sabre.
		Problems for the Typhoon mounted, as the highly complex Sabre continued to give trouble and, just as the Typhoon was becoming operational in mid-1942, a serious airframe fault became evident.

		Sir Sidney Camm however felt that the radial engined Tempest Mk II would offer the ultimate in performance for the Typhoon/Tempest line and, as a result, considerable effort was made to improve the efficiency of the 2,210 hp Centaurus air cooled radial engine.
		A decision was made to concentrate Hawker´s efforts on the Sabre II powered aircraft in order to get the new fighter into operational service as soon as possible.
		The Sabre V´s higher power output made it necessary to have this extra cooling which was especially important since the Tempest VI had been selected to be the standard RAF fighter for service in the Middle East.

		The Sabre represents the apotheosis of the engine designers art in obtaining the greatest possible power from the least possible bulk and with minimal frontal area.
		Other niceties were sometimes of established Napier style, notably the piston crowns with their generously radiused shoulders and considerable clearance from the bore progressively tapering to a narrower clearance just above a low-set wedge-section compression ring.
		Add the particular virtues of the small-cylindered Napier layout, contributing high crankshaft rates and vast breathing capacity in relation to the physical size, and with all bearings (thinwall shells, to be copied by Vandervell), and shafts fully supported in a naturally rigid structure - the result could hardly fail to be a prodigy.
