bristol centaurus reliability

I remember one engine failure at Labuan where a cylinder poked its nose out of a top cowling, holding down studs had sheared. An additional Hawker Tornado was built fitting a Bristol Centaurus engine and used extensively as a testbed. These mounts prevented the installation of the Centaurus XII engine (which was originally intended to power production Tempest IIs) and the Centaurus V was chosen as the production power plant. Powered by a Bristol Centaurus engine, the Sea Fury was one of the fastest piston-powered airplanes ever made. There were some development difficulties, though by 1944 the Centaurus was rated at over 2500hp. Production was slow due to emphasis being placed on the smaller Hercules. Someone said sleeve valve engines are simpler than poppet valve engines. By: Christer The new face of Filton. - Edited 1st January 1970 at 01:00. Bristol Centaurus The Centaurus is a large 53.6 litre sleeve-valve radial engine which, in its later versions similar to the one on display, reached the upper limits of its category and delivered 3,220hp AT 2,800rpm with methanol-water injection. This compact 18-cylinder, twin-row radial powered a huge number of World War II fighters, bombers and cargo planes, then went on to propel fleets of 1950s airliners.

Right into the mid 80’s he organised several operator syndicate purchases which enabled some of these types to linger on, providing commercial/military service into the late 80’s, early 90’s. The Tempest II had been intended to be powered by the 2,250hp Sabre Mk IVA in-line liquid cooled engine. It was the ultimate radial engine, and was developed primarily for heavy bomber and transport aircraft. Unfortunatley, none of the aircraft that used it exist in working order anymore.

With production engines in production airframes, Sabre reliability issues were soon encountered. The Miles aircraft lost out to the Bristol Brabazon and was never built. - 8th November 2001 at 20:45 Permalink Seventy-three years after the first R-2800 cranked, wheezed, chuffed, puffed and fired . I know that his is an old topic but I felt some things were missing. The tradeoffs often start immediately behind the propeller, as with U.S.-owned Hawker Sea Furys, in which the original Bristol Centaurus powerplants are often replaced with widely understood Wright R-3350s—the same engine that powered the Boeing B-29. Contact Details. Power ranged from 2,200 to over 3,700 hp (1,640 to 2,760 kW), depending on the model. The Tempest II was powered by the 2,500 h.p. Flew as ground engineer for five hundred hours in both types. Like most Bristol Engines designs, the Centaurus was based on the mechanicals of an earlier design, in this case the "classic" 5.75 in (146 mm) piston from . The Wright R-3350 Duplex-Cyclone was one of the most powerful radial aircraft engines produced in the United States. Germany switched the FW-190 from radial to inline in the D model in search of altitude performance as the BMW radial lacked a good high altitude supercharger. . Setting up the valve timing was intensive work though. The Centaurus-powered Tornado proved much superior in reliability and performance to either the Vulture-powered Tornado or the Sabre-powered Typhoon. Found inside – Page 13HERCULES — two radial piston engines , with Bristol - pioneered sleeve - valves . . . renowned for their reliability and long overhaul life . CENTAURUS AND ... aehs home. The Taurus was developed by adding cylinders to the existing single-row Aquila design and transforming it into a twin-row radial engine, creating a powerplant that produced just over 1,000 horsepower (750 kW) with very low weight. 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. Its range on internal fuel was 775 miles and initial climb rate was 4,520 ft./min. Known as the Bristol Orion (a name used previously for a variant of the Jupiter engine, and later re-used for a turboprop one) this development was also a two-row, 18 cylinder sleeve valve engine with the displacement increased to 4,142 cubic inches (67.9 l). We have lost a few since then. They refused to accept the Rolls Royce instructions, declined invitation to join oil purchasing syndicates, and preferred to believe rumours that other oils would work just as well. The centaurus engine and tempest airframe proved an excellent match and the centaurus was generally regarded as superior to the sabre, particularly in terms of reliability. By the end of the war in Europe, around 2,500 examples of the Centaurus had been produced by Bristol. Pictured is DD815, the third Firebrand Mk I prototype. In 1925 the American Pratt & Whitney company was founded, competing with Wright's radial engines. - 1st July 2016 at 19:46 Permalink Australia.

The bloody lessons learnt from the hundreds of thousands of dogfights fought in the War had been carefully noted by designers. Must have missed this thread first time round. Nothing else came into the equation. Smooth running . I liked Your analogy with furry dice and a Ferrari! The problem is that running a sleeve valve engine at extended high temperature has a tendency to distort the sleeves, and this leads to problems. The Centaurus-powered Tornado proved much superior in reliability and performance to either the Vulture-powered Tornado or the Sabre-powered Typhoon. So the loads and stresses on a sleeve valve are vastly different to a normal one. A sleeve valve is in effect a large tube which fits inside the cylinder, but which contains the piston. The swept volume of the 3350 is slightly higher (1 ltr) and being turbo-compound, more power available. Typical examples of reliability: The Centaurus was almost as big as the Wright R3350 but put out 1000 less hp in the final versions. The good thing being that you didn't have to adjust them anymore. Steve, On another forum I´ve recently been referred to as Indiana Christer. By: Beaufighter VI According the Internet: "The Bristol Centaurus has 18 cylinders in two rows, and is a sleeve-valved radial air-cooled engine. - Edited 1st January 1970 at 01:00.

By: Propstrike The Jupiter was the first of many successful piston engines to be designed and built by Fedden's team, from the 32 h.p. The ultimate World War II fighters such as the Sea Fury and Bearcat were powered by 2500 hp radials like the Bristol Centaurus or Pratt & Whitney R-2800. While Bristol maintained the Centaurus dated from July 1938 (when it was originally type-tested), production could not start until 1942 owing to the need to get the Hercules into production and improve the reliability of the entire engine line. Nor was there any real need for the larger engine at this early point in the war, when most military . - 30th June 2016 at 20:34 Permalink On balance though, provided both types are operated within the design limits there should be little difference in overall reliability. Over 8,000 were produced. This was a winner and wear reduced and a longer engine life. Its range on internal fuel was 775 miles and initial climb rate was 4,520 ft./min. The Bristol centaurus was no better or worse than any of the US air cooled radials from the end of the war. However, Sabre engine production was allocated to the Typhoon, and the Firebrand was reengined with the Bristol Centaurus. Indeed, of all the sleeve-valve engine designs, only two managed to establish a level of working reliability and reasonable time between overhauls — the Centaurus and the Hercules. Just click the profile icon, some nuts state their full and real names there. As has been posted, the Centaurus was a more reliable engine than other British ones. Found inside – Page 21...

Phil, By: Christer This resulted in what was probably the cleanest radial engined fighter of Second World War. The original Bristol proposal was to re-engine the Lockheed Constellation with Bristol Centaurus radials, but Treasury refused the expenditure of US dollars. This meant that a new engine had to be fitted, the Bristol Centaurus. - Edited 1st January 1970 at 01:00. It's amazing that you found the thread! flat-twin Cherub up to the 3,200 b.h.p. Bristol Centaurus VI 2,585hp in 1944 (but by no means the most powerful of the series). Rolls-Royce lead the field with the 2 stage gear driven supercharger development; the US lead in exhaust driven turbochargers for high altitude operations. Development was delayed by frequent changes of specification, and by power and reliability issues with the new Centaurus sleeve-valve engine. Moves to shut down the Centaurus engine project completely so that Bristol could concentrate on both increasing the reliability and production volume of the Hercules had resulted in loud howls of indignation from the Bristol Board and more political pressure, the result of this was that the Bristol company had been given time and resources to . - Edited 1st January 1970 at 01:00. - Edited 1st January 1970 at 01:00.

Since 1985 including today I count eight serious incidents with UK Sea Fury's - five due to engine failure (four = Bristol Centaurus). The Jupiter piston was still in use in the contemporary 14-cylinder Hercules, which was being brought into production during the design of the Centaurus. I would imagine fitting American engines was due to their availability of spares. The Centaurus was the final development of Bristol Engine Co's series of sleeve valve radial aircraft engines, an 18-cylinder two-row design that eventually delivered over 3,000 hp (2.2 MW). It had a single machine gun in the nose, a two-gun dorsal turret, and a four-gun tail turret, all with 7.7-millimeter guns. I´m still hoping for a comment from Phil about what he learned from the "service time guy"! - 1st July 2016 at 19:40 Permalink The Centaurus was the final development of the Bristol Engine Company's series of sleeve valve radial aircraft engines.The Centaurus is an 18-cylinder, two-row design that eventually delivered over 3,000 hp (2,200 kW). All Rights Reserved. The Hercules' approximately 1,500 hp was simply better suited to the existing airframes then in production.In fact, the Centaurus did not see any use until near the end of the war, first appearing on an upscaled version of the Vickers Wellington, the Warwick. But to my view putting an American engine in a Fury is like hanging furry dice in your Ferrari! This is said to be due to the unreliability of the BC and, though realizing that it´s a complex design, I´ve always wondered what causes the unreliability.

It is also slightly more reliable, the figures given being in the range of 3500 hrs TBO. The Pratt & Whitney R-2800 was the most remarkable piston aircraft engine ever built. Brian Peaden, a mechanic from Reno, Nevada, has created a cutaway of an 18 cylinder Bristol Centaurus engine and attached a small electric motor to spin it in slow motion. GB445558329. Centaurus engines did become available in quantity, leading to the "Warwick GR.II" for maritime patrol, powered by twin Centaurus VI engines providing 1,864 kW (2,500 HP) each. The nearly 40% higher capacity was achieved by increasing the stroke from 6.5 to 7 in (170 to 180 mm), and by changing to two rows of nine cylinders instead of two rows of seven, but the overall diameter of the Centaurus was only just over 6% greater. - Edited 1st January 1970 at 01:00. - 10th November 2001 at 00:23 Permalink Found inside – Page 447During the period under review , it has continued to attract a limited amount of attention ...
