		The Bristol Type 167 Brabazon was a huge airliner built by the Bristol Aeroplane Company in 1949 to fly a large number of passengers on transatlantic routes from England to the United States.
		Bristol had already studied a large bomber design starting as early as 1937, and then the Air Ministry published a tender for a new super-heavy bomber design.
		Bristol's factory in Filton was far too small to handle what was one of the largest aircraft in the world, and the local 2,000 ft (610 m) runway was too short to launch it.

		The Bristol Beaufighter was a mid-wing, cantilever, all-metal monoplane that carried a pilot in the nose and an observer aft of the wings.
		The Bristol Type 175 Britannia was a series of British airliners developed during the 1940s in response to a requirement from BOAC for an airliner for its medium-range Empire routes, and was adopted by the British military in 1959, remaining in service until 1975.
		Bristol Fighter was armed with a synchronized, forward-firing Vicker's machine-gun and two or three Lewis machine-guns on a Scarff ring in the rear cockpit.

		Like most Bristol Engines designs, the Centaurus was based on the mechanicals of an earlier design.
		While Bristol maintained the engine dates to 1938, production couldn't start until 1942 (nor was there a need for it).
		The Centaurus, on the other hand, was considered to be very reliable right from 1942, once the initial bugs had been worked out.

	Bristol Aero Collection
		Bristol started building aero engines on the Filton site around 1920, but the line can be traced back to the Brazil-Staker motorcar manufacturer, who built Rolls-Royce engines under licence during World War I. The company was taken over by Cosmos Engineering, who built the Mercury and the Jupiter radial engines.
		The Centaurus was also used on the Bristol Brabazon prototype, which had four pairs of 2,500 bhp Centaurus engines, each pair driving a set of contra-rotating propellers.
		A scaled-down version of the engine, the Bristol Siddeley Gyron Junior, was used on the Bristol 188 stainless steel research aircraft, which was designed to investigate the effect of supersonic speeds on airframe structure.

		The Bristol Type 175 Britannia was a medium/long-range airliner built by the Bristol Aeroplane Company in 1952 to fly a number of air routes across the British Empire.
		Bristol won both the Type I and Type III contracts, soon delivering their Type I design, the Bristol Brabazon in 1949.
		By the time the first prototype flew on August 16, 1952 BOAC and Bristol had dropped the Centaurus version as the turboprop Proteus had shown such promise.

		The Centaurus is a large 53.6 litre sleeve-valve radial engine which, in its later versions as the one on display, reached the upper limits for its category and delivered 3220 hp at 2800 rpm with methanol-water injection.
		Bristol Mercury XV Like all Bristol piston-engines, the Mercury was an air-cooled radial engine and was developed in 1927 from the earlier supercharged Jupiter, also a 9-cylinder powerplant and from which it differed mainly by having a reduction gear and a shorter stroke.
		However, its versatility eventually enabled it to be mounted on types of aircraft, from twin-engined types as the Bristol Blenheim, to trainers as the Miles Martinet and Master 11, and utility aircraft as the Supermarine Sea Otter and Westland Lysander.

		The Bristol type 166 Buckmaster was an advanced trainer aircraft of the Royal Air Force.
		By 1945, there was a serious gap in performance between the so-called advanced trainers in use, such as the Avro Anson, Airspeed Oxford, dual-contol Bristol Blenheim and Lockheed Hudson - and the combat aircraft which the pilots would be expected to fly on graduation.
		The Bristol response to specification T.I3/43 was to make further use of the Buckingham wing, with yet another new fuselage.

		Negotiations with BOAC were slow, as they were not looking to replace their Constellation fleet until 1954, and the Ministry of Supply stepped in 1948 for an order for three prototypes to prevent the project from stagnating.
		The Centaurus was an established power plant, already in use on the Airspeed Ambassador, Blackburn Beverly and Hawker Sea Fury.
		During the late 1940's Bristols engine department made exceptional progress on Proteus development, such that the BOAC order was amended to include it on all 25 aircraft.

	Unreal Aircraft - Lost Classics - Bristol Brabazon
		Bristol Aeroplane Company had already done a design study in 1937 for a long-range strategic bomber, so when invitations were extended in 1942 for studies related to a heavy bomber, they were at an advantage.
		When the Brabazon Committee's intercontinental airliner was proposed, however, the work already done by Bristol late in WW2 on their heavy bomber design led to them being given an order for two prototypes, to be followed by a possible ten production aircraft.
		After considering a variety of capacity and design criteria, in November 1944 the concept solidified around a 177 ft. fuselage with 230 ft wingspan (35 ft. more than a Boeing 747), powered by eight Bristol Centaurus 18-cylinder radial engines nested in pairs in the wing.

	Trans Global Aircraft
		The Bristol 188 was developed by Bristol Aeroplane Co to meet specification ER134T for a M2.5 research aircraft.
		During the development of the Avro 730, Avro suggested a 3/8 scale analogue of the Avro 730, so perhaps the Bristol 188 was part of this programme.
		The 188 was intended to "thermally soak" the airframe for long periods, but was unable to maintain these high speeds for long periods due the fuel consumption of the Gyron.

	The Hawker Tempest Page
		During the test flight of the engine in a Tornado prototype (HG641) the engine and oil temperatures remained constantly near the maximum allowable and there was a high amount of carbon monoxide gas in the cockpit.
		It was first fitted with the Centaurus IV and later with the Centaurus V. LA607 was from the beginning fitted with the enlarged dorsal fin and a sliding canopy and was earmarked for powerplant tests and development.
		All of Bristols aircraft and Hawkers first batch were built as fighters, while the rest of Hawkers production were built as fighter-bombers with strengthened wings.

		n the 1930s Bristol developed a new line of radials based on the sleeve valve principle, which would develop into some of the most powerful piston engines in the world, and could continue to be sold into the 1950s.
		In 1956 the division was renamed Bristol Aero Engines, and then merged with Armstrong Siddeley in 1958 to form Bristol Siddeley as a part of the airframe mergers that formed BAC.
		The Centaurus, on the other hand, was considered to be very reliable right from 1942.

	The Hawker Typhoon, Tempest, & Sea Fury
		One was the Bristol "Centaurus" sleeve-value air-cooled 18-cylinder radial engine, but prewar air races had biased many in the British air establishment against radials, and engine options felt to be most promising were two 24-cylinder water-cooled inline designs, the Rolls-Royce "Vulture" and the Napier "Sabre".
		The first Centaurus Tempest, or "Tempest Mark II", flew on 28 June 1943 with a Centaurus IV, and was followed presently by the second.
		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.

		On reading the piece, I was left wondering if this was really the same aircraft that I watched grow stringer by stringer and rib by rib, not to mention witnessing the laying of the runway and construction of the massive assembly hangar, all of which were part of the same project.
		The basis of the Bristol Brabazon was the 1941-'42 design work already done on a projected 100-ton bomber that, to reduce the considerable drag imposed by four engine nacelles, called for engines to be buried within the wings.
		In any case, as I recall, it was originally proposed to build the Brabazon at the satellite Bristol establishment on the Atlantic coast, at Weston-super-Mare, where the runway could be lengthened with no inconvenience.

	Brief History of the Typhoon and Tempest
		These engines were the Rolls-Royce Vulture, a liquid-cooled 24-cylinder X-type based on a pair of V-12 Peregrines fastened together back-to-back, the Bristol Centaurus, an 18-cylinder sleeve-valve radial, and the Napier Sabre, a liquid-cooled sleeve-valve 24-cylinder H-type that resembled a pair of flat twelves bolted together.
		The engines were expected to have horsepower per pound ratios of 0.79, 0.95, and 1.12 respectively, but the development of the latter two was expected to be prolonged as their designs pushed the "state of the art".
		Hawker designed a version of their submission for each of the engines, the Vulture-powered model was the Tornado, that using the Centaurus was the Tempest and the Typhoon used the Sabre.

	ICARUS
		It was then redesigned to become a fast strike aircraft carrying a large torpedo, and powered by a Bristol Centaurus radial.
		Its powerful Bristol Centaurus engine and thirteen-foot diameter propeller produced extreme torque swing on takeoff, which could only be countered by the abnormally large vertical tail fin and rudder.
		The Firebrand was also very difficult to deck land, since the pilot sat closer to the tail than the nose, with predictably poor visibility.

		They retained the 1,675 hp (1250 kW) Bristol Hercules VI or XVI 14-cylinder sleeve-valve double-row air-cooled radial engines, but the nose and dorsal turrets were removed and faired over leaving the Frazer-Nash F.N.20A tail turret as the only defensive armament.
		The Stirling was capable of towing one General Aircraft Hamilcar heavy freight glider or two Airspeed Horsa medium gliders in an assault role, or up to five Hotspurs on a ferry flight or training.

	The Hawker Typhoon and Tempest - Great Britian
		Design development was allowed to continue, however, and during 1940 three alternative engine installations were proposed for the Tornado--the Fairey Monarch, the Wright Duplex Cyclone, and the Bristol Centaurus--and experimental drawings for the Centaurus installation were completed.
		The first Centaurus installation had an exhaust collector ring forward of the engine from which a single external exhaust stack pipe led back under the root of the port wing.
		This arrangement soon proved unsatisfactory, so the oil-cooler duct was enlarged and led forward to the nose, while twin exhaust pipes led back from the front collector ring through this fairing to eject under the belly of the fuselage.
