Beardmore Tornado
The Beardmore Tornado was an eight-cylinder inline diesel aircraft engine built in 1927 by William Beardmore and Company of Glasgow, Scotland, and used in the British R101 airship when petrol engines were thought unsafe in the tropics. The model is given as Tornado IIIA or Tornado III C.I. The fuel is described as ''Diesel heavy-oil''. Design and development The engine was designed by combining two four-cylinder units used for railcars into the eight-cylinder (MkI) engine. These were intended to give an output of at 1,000 rpm but in practice, had a continuous output rating of only with a maximum of . At 17 tons for the five, they were six tons above design weight. The weight with the power car was over three tons per engine. The big end bearings were also found to be prone to early failure, In addition, there were two critical vibration frequencies which coincided with idling and cruising speeds, resulting in a limitation on the maximum rpm and consequently a reduction in ...

De Havilland Okapi
The de Havilland DH.14 Okapi was a British two-seat day bomber of the 1910s built by de Havilland. The aircraft was designed as an Airco DH.4 and DH.9 replacement, but it never entered production. Design and development The Okapi was a scaled-up Airco DH.9 with a bigger engine, (the Rolls-Royce Condor) intended as a replacement for the DH.4 and DH.9. Three were built, but due to the end of the First World War the Royal Air Force was reluctant to accept them. The third aircraft was the first to fly, and it was completed by Airco as the DH.14A, a two-seat long-range mail plane. The two military aircraft were completed by de Havilland in 1921 and used for trials. One suffered a fatal crash at Burnham Beeches on 10 February 1922 and no production aircraft were ordered. G-EAPY The third aircraft was completed as the DH.14A to compete in the Daily Mail transatlantic flight competition.Jackson 1987, pp. 148-152 It had a Napier Lion engine and increased fuel capacity.

De Havilland Highclere
The de Havilland DH.54 Highclere was a single-engined 15-passenger biplane airliner designed to replace the DH.34. Its development ended when Imperial Airways decided to use only multi-engined types. Development The DH.54 Highclere was designed to Air Ministry specification 40/22 for a larger version of the very successful DH.34 and the two aircraft had much in common, both in construction and general layout. Compared with the DH.34, the Highclere's passenger complement increased from nine to twelve, its all-up weight by 56% and its wing area by 70%. They were both single-engined two-bay biplanes with fabric-covered wooden wings and with wooden-framed fuselages covered with thin plywood. Size apart, the wings of the Highclere differed in having no stagger, no upper wing dihedral and in having a larger inter-wing gap, the upper wing now attached to the fuselage by cabane struts rather than directly to the upper fuselage. In response to criticism of the DH.34's high landing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Berkeley
The Bristol Berkeley was built to a British government specification for a single-engine day or night bomber. Three of these two-seat biplanes were built, but no contract for further production was awarded. Development In August 1923, British aircraft manufacturers were invited to submit designs to Air Ministry Specification 26/23, which called for a single Rolls-Royce Condor-engined two-seat day or night bomber. The Berkeley was Bristol's response, designed largely by W.T. Reid with finishing touches from Bristol's longtime chief designer, Frank Barnwell. It was a fabric-covered all-metal structured three-bay biplane, with equal span, unswept and unstaggered wings with Frise-type ailerons on the upper and lower planes. Structurally, the wings were of rolled steel and duralumin. The fuselage was built from steel tubes and had a rectangular cross section. The pilot sat forward of the leading edge of the wing in an open cockpit and the gunner/observer in a cockpit well aft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackburn Iris
The Blackburn Iris was a British three-engined biplane flying boat of the 1920s. Although only five Irises were built, it was used as a long-range maritime reconnaissance aircraft by the Royal Air Force, where it equipped a squadron for four years, being used to carry out a number of notable long-distance flights. The final version of the Iris, the Iris Mark V was developed into the aircraft that replaced it in Squadron service, the Blackburn Perth. Development and design In 1924, the British Air Ministry issued Specification R.14/24 for a long-range reconnaissance flying boat for the Royal Air Force. To meet this requirement, Blackburn Aircraft proposed the R.B.1 (Reconnaissance Biplane 1), designed by Major John Douglas Rennie, who as Chief Technical Officer worked with John Cyril Porte at the Seaplane Experimental Station, Felixstowe.London 2003, p. 99. The R.B.1 was a three-engined, three- bay biplane. The equal-span wings were of mixed wood-and-metal construction, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beardmore Inflexible
The Beardmore Inflexible, also known as the Rohrbach Ro VI, was a three-engined all-metal prototype bomber aircraft built by William Beardmore and Company at Dalmuir, Scotland. Design and development William Beardmore and Company had acquired a licence for the use of the Rohrbach principle for stressed-skin construction. Using these principles and drawings supplied by Rohrbach for the RoVI, the Beardmore company built a massive all-metal three-engined transport, the ''Beardmore Inflexible''. The aircraft was built in sections at Dalmuir between 1925 and 1927 which were shipped by sea to Felixstowe and from there delivered by road to the Aeroplane & Armament Experimental Establishment (A&AEE) at Martlesham Heath Airfield where it first flew on 5 March 1928. It appeared at the Hendon RAF Display later in the year. The aircraft was structurally advanced for its time and had good flying qualities. It was also a very large aircraft for the time, having a wingspan of - around great ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro 557 Ava
The Avro Type 557 Ava was a British twin-engined biplane torpedo bomber of the 1920s. It was developed by Avro to meet a requirement for a heavy torpedo bomber for the Royal Air Force but was unsuccessful, only two prototypes being built. Design and development The British Air Ministry produced Specification 16/22 in 1922 for a long-range land-based torpedo bomber. The specification required that the aircraft be capable of carrying a 21 in (533 mm) torpedo or an equivalent weight of bombs and produced responses both from Blackburn Aircraft (the Cubaroo) and Avro. Roy Chadwick, chief designer of Avro, initially produced a single-engined design, the Avro 556 powered by a Napier Cub engine, similar to the Cubaroo. This was rejected in favour of a twin-engined aircraft using two Rolls-Royce Condor engines, the Avro Type 557 Ava and winning an order for two prototypes from the Air Ministry. Completed in secret (owing to its armament of a 21 in (533 mm) torpe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro Andover
The Avro Andover was a 1920s British military transport aircraft built by Avro for the Royal Air Force. Four aircraft were built, in two versions. Three aircraft, the Type 561, were used as flying ambulances. The sole example of the Type 563 was used as a 12-seater transport. Design At the beginning of the 1920s the Royal Air Force required a successor for the outdated Airco DH.10 Amiens on the Cairo to Baghdad "Desert Air Route". In response Avro designed and constructed the Avro Andover, a single-engined biplane designed to serve as a passenger plane and also as an air ambulance. The fuselage was a steel tube frame covered with canvas and plywood. While the fuselage was a completely new design, the wings, undercarriage and the tail unit were taken from the Avro Aldershot bomber. The pilot and navigator sat in an open cockpit directly under the leading edge of the upper wing; a passageway led from the cockpit to the passenger cabin. The aircraft held twelve passengers (six on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro Aldershot
The Avro 549 Aldershot was a British single-engined heavy bomber aircraft built by Avro. Development and design The Aldershot was designed to meet the 1920 British Specification 2/20 for a heavy long-range day and night bomber to be powered by a Rolls-Royce Condor engine.Jarrett 1993, p.9. The specification required a range of 500 miles (800 km) and a bombload of 2,000 lb (900 kg), originally comprising a single World War I vintage 1,800 lb (820 kg) SN bomb, but then changed to four 500 lb (230 kg) bombs carried externally or eight 250 lb (114 kg) bombs internally.Mason 1994, p.136.Sharpe, Michael. ''Biplanes, Triplanes, and Seaplanes''. London, England: Friedman/Fairfax Books , 2000. . The Air Ministry gave Avro a contract for two prototypes, designated Aldershot I, on 2 December 1920, in competition with the de Havilland Derby. The first prototype flew at Hamble Aerodrome near Southampton in October 1921.Mason 1994, p.137. As ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
