Rolls-Royce Merlin - Wikipedia, the free encyclopedia Two Peregrines bolted together on a common crankshaft into an X-24 layout would create the 1,700 hp (1,300 kW) 44 litre Rolls-Royce Vulture, for use in larger planes like bombers. Originally it had a grille from a Rolls Royce, but after complaints from them he had to change it. There was also the possibility that the famous 36 litre 'R' engine from the Supermarine racing planes could be developed into a 1,500 hp (1,100 kW) class engine of its own, itself a development of the Rolls-Royce Buzzard, a scaled up Kestrel. en.wikipedia.org /wiki/Rolls_Royce_Merlin

Rolls-Royce Vulture - Wikipedia, the free encyclopedia The Rolls-Royce Vulture (and the related Peregrine) were aircraft engines, and probably the least successful power units ever produced by Rolls-Royce. Apart from being seriously under the designed-power, in the Vulture's case the problem was the frequent failure of the big-end bearings, found to be caused by a breakdown in lubrication. The Vulture had been intended to go into the Hawker Tornado but with the cancellation of Vulture development, Hawker's abandoned the Tornado and concentrated on the Napier Sabre version, the Typhoon. en.wikipedia.org /wiki/Rolls-Royce_Vulture

The History of ROLLS ROYCE at HUCKNALL Rolls Royce went away from this idea and pursued their own ideas of small jet engines for vertical lift which was later demonstrated by Short SCI aircraft and so finished a small part of Rolls Royce history in the new jet age. By this time Rolls Royce were beginning to put into practice some of the new theories of radiator and subsequent pipe work had to be built into the installations and streamlined to create as little drag as possible. The results of these tests had shown that Rolls Royce had been justified in taking this step to do their own flight development but they were still having to rely on other people to carry it out. homepage.ntlworld.com /g6nhy.uk/rolls.htm

Avro 679 Manchester The Vulture was a very complex engine, effectively two Rolls-Royce Peregrine (Kestrel) 12-cylinder engine blocks joined together (one inverted on top of the other) with the lower pair being inverted to give an X-type arrangement driving a single crankshaft and with an intricate lubricating system. Manchester B.Mk IA - Two 1,760 hp (1312 kW) Rolls-Royce Vulture I 24-cylinder X-form inline piston engines. The engine was actually created by joining two Rolls-Royce Peregrine (Kestrel) 12-cylinder engine blocks together on a single crankcase with the lower pair being inverted to give an X-type arrangement. www.kotfsc.com /aviation/manchester.htm

ROBOTECH: REF Aircraft Technical Files - Vulture After 2033, the Vultures that remained were slowly phased out of service in favor of the Beta Fighter and in 2043 only 100 reserve mecha remained in Planetary Guard squadrons on Tirol. The Vulture provides full protection from nuclear, biological, and chemical hazards, using an overpressure cockpit environment activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. Most notably, the Vulture was literally built around one of the largest single guns ever mounted on an aircraft, the EP-100. www.artemisgames.com /robotech/Aircraft/Vulture.html

avrolancaster Essentially, the Vulture was two Rolls-Royce Peregrine engines bolted together, one on top of the other, the two "V" type engines essentially producing an "X" type engine. The Rolls-Royce Vulture was an engine that was simply ahead of its time. From these wings were removed the two troublesome Vulture engines, and in their place four Merlins added. www.hellzapoppin.demon.co.uk /avrolancaster.htm

The Hawker Typhoon, Tempest, & Sea Fury With Vulture development becoming a bottleneck, the decision was made to get rid of the two Vultures and fit the bomber with four Rolls-Royce Merlin inlines, and the result was the superlative Lancaster. One design was to be powered by the Rolls-Royce Vulture and was known as the "Type R", and the other was to be powered by the Napier Sabre and was known as the "Type N". The Vulture was so unreliable that one bomber squadron equipped with the Manchester joked that they should be redesignated as infantrymen. www.vectorsite.net /avcfury.html

People Rolls-Royce Centenary - A Century Of Innovation He was at the helm in Royce's last years, and continued without support from 1933 through Wormald's declining years until the appointment of Ernest Hives to succeed Wormald as general manager in 1936. To Sidgreaves goes the credit for acquiring the Bentley motor car business, and it was during his stewardship that the Derby Bentley, Phantom III 20/25hp, Goshawk, Peregrine, Vulture and Merlin were launched. To have ventured a significant contribution to the launch costs of the prototype Fairey Battle, Hawker Hurricane and Supermarine Spitfire in order to secure the selection of the Merlin remains perhaps the greatest testimony to his stature. 100.rolls-royce.com /people/index.jsp?id=152

RAF History - Bomber Command 60th Anniversary Rolls Royce, keen to produce as many Merlin engines as possible for other aircraft, could not devote as much development time as was necessary to the X-Type (or Vulture as it was later named). Delays to the first flight of the Manchester were caused by successive design changes ordered by Rolls Royce as they revised the Vulture during 1938, but the aircraft finally took to the air on 25 July 1939. With orders for the Manchester standing at 1,200 and Rolls Royce increasingly under pressure to concentrate on Merlin production, work on the four-engined airframe continued and showed that control could be improved by increasing the size of the twin rudders. www.raf.mod.uk /bombercommand/manchester.html

Hawker Typhoon and Tempest history At the proposal of the Air Ministry, Camm also prepared studies for an alternative version of his fighter powered by the Rolls-Royce Vulture engine, and increased the ammunition capacity of both machines to 500 r.p.g. The "X" form of the Tornado's Vulture engine had not permitted installation above the front spar as was the Typhoon's Sabre and, in consequence, the overall length of the former was 32 ft. 6 in. As a result of the slightly more advanced development status of the Vulture engine which had been designed along more conventional lines than the Sabre, the Type " R " was the first of the two fighters into the air, flying in October 1939. www.military.cz /british/air/war/fighter/tempest/history.htm

Hawker Typhoon - Iridis Encyclopedia 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 two resulting models became known as the 'R' and 'N' (based on the engine manufacturer) and were very similar – the Vulture powered R plane had a rounder nose profile and a ventral radiator, whereas the Sabre powered N had a flatter deck and a chin mounted radiator. The engines were similar in that they were both 24 cylinder designs that were designed to deliver over 2,000hp, and different primarily in the arrangement of the cylinders - an H-block in the Sabre and an X-block in the Vulture. www.iridis.com /Hawker_Typhoon

Typhoon The Rolls Royce Vulture was the most promising of the two prototypes, so the Tornado took to the air before the Typhoon in October 1939. Two airframe variants were developed, the R-type (for the Rolls Royce Vulture engine), and the N-type (for the Napeir Sabre engine). This requirement was looking for an advanced fighter, powered by the Rolls Royce Vulture X-type or the Napier Sabre H-type engine, and heavier armament in the way of 4 × 20 mm cannons. www.turnkeyrc.com /typhoon.htm

RROC(A) Online Library: Rolls-Royce Armoured Cars Royce would not have approved of rolling changes without the clutch, a technique that was needed on four occasions to my knowledge. It was possible to let a car pass, run to the side of the car and roll a bomb or light a fire under the car, without the crew being able to see the enemy or fire at them. Any dig-in by the front wheels breaking this crust and the car was liable to roll - this misfortune overtook the 'Cheetah' as she mounted a bank and turned too sharply at the crest. www.rroc.org.au /library/sg_ac.html

Avro Lancaster When the Vulture proved unreliable, A. Roe's chief designer Roy Chadwick switched to a design using four of the more reliable Rolls-Royce Merlin engines instead. The original design was for a twin-engined heavy bomber to be powered by the Rolls-Royce Vulture engines. It was withdrawn from service in 1942 with only 200 aircraft built. www.brainyencyclopedia.com /encyclopedia/a/av/avro_lancaster.html

History of the Typhoon The other two were to use the Rolls-Royce Vulture, comprising two 12-cylinder engines joined in an 'X' layout, driving a common crankshaft. The two versions were designated the N-type, for the Napier Sabre (the Typhoon) and the R-type, for the Rolls-Royce Vulture (the Tornado). What finally killed the Tornado was the government demand to Rolls-Royce to work flat out on a new 12-cylinder engine, the Griffon, which, although much smaller and lighter than the 24-cylinder Vulture, developed about the same horsepower. www.eagle.ca /~harry/aircraft/typhoon/ty_hist.htm

Safety Fast January 2000 - FROM LITTLE ACORNS DO BIG OAKS GROW One was Rolls Royce who were developing their piston engines for fighter aircraft, and were well entrenched into a very complex 'X24' "Vulture" engine; the other was Napier with their 'H24' "Sabre" engine. Whilst both problems were later cured, Napier fell from the scene, and Rolls Royce stuck to 'V 12' engines such as the Merlin and Griffon. The Rolls Royce engine had cylinderheads with normal twin-ohc poppet valves, Napier used sleeve valves. www.british-cars.org.uk /kimber/mgcc/sf/000103.htm

Hawker It has been said that Rolls Royce was too occupied with the Merlin to devote adequate resources to the proper development of the Vulture. Yet there exists significant evidence that the design was flawed beyond correction, and that Rolls Royce knew this early into the program. The Vulture engine did not produce the specified horsepower. home.att.net /~ww2aviation/Hawker.html

BLACKBURN B20 On 28th August 1998 Royal Navy divers recovered one of the Rolls Royce Vulture II engines of the Blackburn B20 prototype from the sea. If, on the other hand, the B20 had been ordered into production later, after the switch to Rolls-Royce Vulture engines as the powerplants, an alternative engine would have been needed when production of the Vulture was stopped to allow Rolls Royce to concentrate on the Merlin. The only choice available was the Rolls-Royce Vulture 24 cylinder of 1,700 hp. freespace.virgin.net /john.dell/blackburn_b20.htm

Avro Manchester - free-definition The specification called for a twin-engined heavy bomber using the powerful Rolls-Royce Vulture 24-cylinder X-type engine which was essentially two Rolls-Royce Peregrine Vee-type cylinder blocks on top of each other, the bottom one inverted to give the "X" shape. Handley Page's response to the engine's faults was to switch the Halifax to four of the less powerful but more reliable Rolls-Royce Merlin X engines however Avro persisted with the Vulture and the Manchester went into production, entering service with RAF Bomber Command in November 1940. When developed in 1935, the engine had promise—it was rated at 1,760 hp—but it proved woefully unreliable and had to be derated to between 1,480 and 1,500 hp. www.free-definition.com /Avro-Manchester.html

MUSTANG! Ronnie Harker Obituary He joined Rolls-Royce aged 16 from Shrewsbury School as an apprentice, enthusiastically taking up flying after visiting the 1927 Hendon Air Pageant. After Rolls was hit by the Depression he was laid off, but with the help of his father he continued to fly as a club pilot. For his wartime work Harker was appointed OBE and given the Air Efficiency award.Harker stayed with Rolls after the war, becoming a sales executive in 1947 and military aviation adviser 10 years later. www.geocities.com /koala51d/harker.html

Hawker Typhoon Ib It was first designed as a low-level interceptor to be powered by the Napier Sabre engine or the Rolls-Royce Vulture engine. With the Vulture, it was known as the Tornado. Although the Typhoon flew after the Tornado, problems with the Vulture engine led to its cancellation, and the Typhoon was ordered into mass production. www.rcaf2000.net /typhoon/typhie.htm

Slightly OT- Rolls Royce Nene- - Scale Models Rolls named their piston engines after birds of prey; Merlin, Eagle, Kestrel, etc. Their turbine engines are named after rivers; Trent, Adour, Conway, etc. Bristol used mythological names for their engine; Centarus, Perseus, etc. Rolls picked up those engines in the consolidation of the British aero industry in the 60's and 70's. > > Jerry 47 > > > > Probably, but most of the RR piston engines were named after birds or > other flying things: Eagle, Kestral, Merlin, Peregrine, Vulture, > Goshawk, Buzzard, Griffon--OTOH, the Exe is a river name. www.hobbytalk.org /_Slightly_OT-_Rolls_Royce_Nene--25991545-303-a.html

halifax.htm Upon realising the drawbacks of the Vulture, Handley-Page redesigned the HP-56 to accept four of the proven and widely used Rolls-Royce Merlin engines; and it would be under this new design, designated HP-57 or Halifax Mk.I, that the aircraft would enter service with the Royal Air Force. The Handley Page twin-engine design designated the HP-56, called for the use of two Rolls-Royce 24 Cylinder Vulture engines. It was generally liked by the aircrews who flew it and when the time came, very few are said to have had any desire to swap it for the so called "superior" Avro Lancaster. www.lancaster-archive.com /halifax.htm

Rolls-Royce Merlin and Griffon Based on their experiences, Rolls-Royce decided to make the crankcase and cylinder blocks as 3 separate castings, with bolt-on ramp heads to the cylinders. The Merlin B was tried with a ramp head to the cylinder which had improved fuel mixing and flame propagation in Rolls auto engines, and in February 1935 delivered 950HP at 11000 feet equivalent. A decision was made by Sir Henry Royce to develop a new engine using some of the experience of the Schneider Trophy winning 'R' engine. www.spitfiresociety.demon.co.uk /engines.htm

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 Tornado was the first to fly in October 1939 as its Vulture was more mature than its competitors. 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". orbat.com /site/sturmvogel/tiffie.html

NLS - The Lancaster Bomber He added twelve feet to the wingspan and replaced the two troublesome Vulture engines with four of the proven Rolls Royce Merlins V-12's and the result was the Lancaster which made its maiden flight in January, 1941. The prototype twin-engined Manchester flew in 1939 but was plagued by instability and problems with its complex, 24 cylinder Rolls Royce Vulture engines. T he proven Rolls Royce Merlin engines were much in demand for many types of aircraft. www.lancastermuseum.ca /lancbomber.html

WIMPY AND LANC Designed by Roy Chadwick for A.V.Rowe Ltd. and called the Manchester, it was fitted with two Rolls Royce Vulture engines, a new type that proved to be troublesome. Later Rolls Royce Merlins and Bristol Hercules were used. Chadwick redesigned the wing and fitted four Rolls Royce Merlins creating the mighty Lancaster. www.gordonstooke.com /460squadron/aircraft.htm

Lancaster Bomber Chadwick always doubted whether Rolls Royce could devote enough time to the development of the Vulture engine with the approaching war putting major demands on the tried and tested Merlin engine which had to be given priority. This twin engined plane was essentially a sound design, but had one major handicap, the radically new Rolls Royce Vulture engines. Chadwick's fears were justified when the Manchester went into squadron service in November 1940 at RAF Waddington fitted with Vulture engines which were prone to mechanical problems and fires. homepage.ntlworld.com /julie.bell102/lancaster.html

Lancaster History The Vulture was supposed to be a replacement for the the very successful Rolls Royce Merlin engine. It was a very complex 24 cylinder X type design, based on four Rolls Royce Peregrine Engines connected to a common crankshaft. At the time, it was thought that the Vulture would be the new 2,000 hp class of powerplant. www.kwsurplus.com /spitcrazy/lancasterhistory.htm
