The Napier Sabre is a British H-24-cylinder, liquid-cooled, sleeve valve, piston aero engine, designed by Major Frank Halford and built by D. Napier & Son during World War II. The engine evolved to become one of the most powerful inline piston aircraft engines in the world, developing from 2,200 hp (1,600 kW) in its earlier versions to 3,500 hp ...

2020年9月20日 · Montague Napier and Bill Nowlan laid out the design for a liquid-cooled, vertical H, 24-cylinder diesel engine that used sleeve valves. Given the Napier designation E101, the engine had a 5.0 in (127 mm) bore, a 4.75 in (121 mm) stroke, and …

The new E101 24-cylinder C.I. engine now had the identical 5” bore and 4.3/4” stroke to that which also formed the petrol fuelled E107 Napier Sabre engine of 1935 onwards. Two and six cylinder test units (E101T and E101/6T) were built followed by a full 24-cylinder version.

Typhoons were powered by the Napier Sabre IIA and IIB engines which were able to power them to a top speed during level flight of 412mph.

2019年10月29日 · It is a 24-cylinder piston engine with sleeved valves. Actually it is better described as two 12-cylinder horizontally opposed engines*, fused together in an ‘H’ cross section, as opposed to its famous ‘competitor’ the V-shaped 12-cylinder Rolls Royce Merlin.

Gradually the Series I (E114) engine was evolved and type tested in June 1940 at a maximum power rating of 2,060 BHP. In early 1939 tests were undertaken with a special grounded boosted version of the Sabre to be used in a Heston aircraft for an attack on the world’s speed record.

Fitted to the Typhoon and other aircraft, the Napier Sabre weighs 2,360 lb and develops 2,200 bhp at 3,700 rpm. It measures approximately 80” by 40” by 43” and is a compact 24-cylinder horizontal H-type sleeve-valve engine with a bore and stroke of 5.000” and 4.750” respectively, giving a total swept volume of 36.69 litres.

Napier’s unusual H-shaped engines were originally designed in 1928 with 16 air cooled cylinders. Proposed in 1935, first run in 1937 and type tested in 1940, the Sabre was intended for high-altitude fighters.
