Cirrus-Hermes Engineering Company
The Cirrus and Hermes or Cirrus-Hermes are a series of British aero engines manufactured, under various changes of ownership, from the 1920s until the 1950s. The engines were all air-cooled, four-cylinder inline types, with earlier ones upright and later designs inverted. The first Cirrus design was created for the planned de Havilland Moth light aeroplane and, when it appeared in 1925, created the market for private flying. It and its successors were widely used for private and light aircraft from that moment on. Design and development ADC The Cirrus engine originated in Geoffrey de Havilland's 1924 quest for a powerplant suited to a light two-seat sports biplane which would become the de Havilland Moth. No suitable engine existed at the time combining an appropriate level of power with light weight, low cost and high reliability. The Aircraft Disposal Company, also known as Airdisco and ADC, were producing the low-cost Airdisco V8 which had been developed by Frank Halford from t ...

De Havilland Moth
The de Havilland Moths were a series of light aircraft, sports planes, and military trainers designed by Geoffrey de Havilland. In the late 1920s and 1930s, they were the most common civilian aircraft flying in Britain, and during that time every light aircraft flying in the UK was commonly referred to as a Moth, regardless if it was de Havilland-built or not. The first Moth was the DH.60 - a straight-winged biplane two-seater. To enable storing the plane in small spaces, the DH.60's wings could fold backwards against the fuselage. "Like a moth" remarked Geoffrey de Havilland, an avid lepidopterist, so the plane was nicknamed Moth from the drawing board on. The Moth was one of the first practical light aircraft designs to be intended for civilian training and recreational use, rather than for military buyers. The Moth was also one of the first light aircraft to be mass produced, and was available to a much wider section of the general public than previous aircraft designs. Fi ...

Blackburn Aircraft Limited
Blackburn () is an industrial town and the administrative centre of the Blackburn with Darwen borough in Lancashire, England. The town is north of the West Pennine Moors on the southern edge of the Ribble Valley, east of Preston and north-northwest of Manchester. Blackburn is the core centre of the wider unitary authority area along with the town of Darwen. It is one of the largest districts in Lancashire, with commuter links to neighbouring cities of Manchester, Salford, Preston, Lancaster, Liverpool, Bradford and Leeds. At the United Kingdom Census 2011, 2011 census, Blackburn had a population of List of urban areas in England by population, 117,963, whilst the wider borough of Blackburn with Darwen had a population of List of English districts by population, 150,030. Blackburn had a population of 117,963 in 2011, with 30.8% being people of ethnic backgrounds other than white British. A former mill town, textiles have been produced in Blackburn since the middle of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westland Widgeon (fixed Wing)
The Westland Widgeon was a British light aircraft of the 1920s. A single-engined parasol monoplane, the Widgeon was built in small numbers before Westland abandoned production in 1929. Development and design In 1924, the British Air Ministry, eager to encourage the development of cheap civil aircraft suitable for use by private owners and flying clubs, sponsored a competition for a two-seat ultralight aircraft, which had to be powered by an engine of 1100 cc displacement or less and capable of carrying a load of at least 340 lb (155 kg). To meet this requirement, Westland Aircraft produced two designs, the Woodpigeon biplane, and the Widgeon parasol monoplane. Unable to decide which design would be superior, Westland decided to build both types.James 1991, p.104. The Widgeon first flew at Westland's Yeovil factory on 22 September 1924, eight days after the first of two Woodpigeons.James 1991, p.111. Its fuselage, which was very similar to that of the Woodpigeon, wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Mussel
The Short S.7 Mussel was a single-engined two-seat monoplane built by Short Brothers to test the performance of their duralumin monocoque floats. Two were built. Development Having demonstrated the watertightness and corrosion resistance of duralumin monocoque flying boat hulls with the Short Cockle, Shorts became leaders in the design of metal floats for seaplanes. The floats for both the Supermarine S.4 and Gloster III Schneider Cup seaplanes were built by Shorts. They had built their own hydrodynamic testing canal at their Rochester base to explore the performance of floats on the water and decided to build a small aircraft to test them in flight. This was the Short S.7 Mussel; the name was a natural complement to the Cockle but also a nod to "Mussel Manor", the clubhouse on Shorts' first airfield at Sheppey. It was a two-seat, single-engined low-winged monoplane, mounted originally on twin floats. Like the slightly earlier Short Cockle, Satellite and Springbok, it ha ...

Avro Baby
The Avro 534 Baby (originally named the "Popular") was a British single-seat light sporting biplane built shortly after the First World War. Development The Avro Baby was a single-bay biplane of conventional configuration with a wire-braced wooden structure covered in canvas. It had equal-span, unstaggered wings which each carried two pairs of ailerons. Initially, the aircraft was finless and had a rudder of almost circular shape. There were later variations of this. The main undercarriage was a single-axle arrangement and with a tailskid. The first Babies were powered by a water-cooled inline Green C.4 engine of pre-1914 design that had previously been installed in the Avro Type D, though thoroughly remodelled postwar by the Green Engine Co. Ltd.Jackson 1990, p. 165. It produced 35 hp (26 kW). Most of the later Babies also used this engine design, new-built from original Green drawings by Peter Brotherhood Limited of Peterborough, though some variants used either a ...

Avro Avian
The Avro Avian was a series of British light aircraft designed and built by Avro in the 1920s and 1930s. While the various versions of the Avian were sound aircraft, they were comprehensively outsold by the de Havilland Moth and its descendants. Design and development The Avro 581 Avian prototype was designed and built to compete in the Lympne light aircraft trials at Lympne Aerodrome in September 1926. Its wooden fuselage was based on that of the Avro 576 autogyro, but it was fitted with conventional biplane wings and powered by a 70 hp (50 kW) Armstrong Siddeley Genet engine. It performed well at the trials, but was eliminated due to engine failure. In early 1927 it was re-engined with an ADC Cirrus engine as the Type 581A and sold to Bert Hinkler. Production aircraft were designated Type 594 and were built in a number of versions, mainly powered by Cirrus engines.Jackson 1990, pp. 249, 256. A version with a welded steel tube fuselage was produced in 1929 as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ADC Cirrus
The ADC Cirrus is a series of British aero engines manufactured using surplus Renault parts by the Aircraft Disposal Company (ADC) in the 1920s. The engines were air-cooled, four-cylinder inline types. They were widely used for private and light aircraft. Design and development The Cirrus engine originated in Geoffrey de Havilland's 1924 quest for a powerplant suited to a light two-seat sports biplane which would become the de Havilland Moth. No suitable engine existed at the time, with both an appropriate level of power and light weight. The Aircraft Disposal Company, also known as Airdisco and ADC, were producing the low-cost Airdisco V8 which had been developed by Frank Halford from their large stocks of war surplus Renault V8 aero engines. De Havilland realised that half of this engine would make an air-cooled four-cylinder inline engine of just the right size and at low cost. He persuaded Halford to undertake its design and development. The cylinders, pistons, con-rods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
