Cirrus Hermes II
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science Museum (London)
The Science Museum is a major museum on Exhibition Road in South Kensington, London. It was founded in 1857 and is one of the city's major tourist attractions, attracting 3.3 million visitors annually in 2019. Like other publicly funded national museums in the United Kingdom, the Science Museum does not charge visitors for admission, although visitors are requested to make a donation if they are able.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Westland IV
The Westland IV and Westland Wessex were British high wing, three-engined light transport aircraft built by Westland Aircraft. Design and development In 1928, Westland began work on a small three-engined airliner, suitable for low volume, "feeder-liner" type operation, as a follow-on to its single-engined Westland Limousine transport. The new type was known as the Limousine IV early in development, which soon became the name Westland IV. The Westland IV was a high-winged monoplane with a mainly wooden structure. The fuselage was of square section and built around spruce longerons and ash frames, with internal wire bracing and fabric covering. The wings had wooden box spars and spruce wing ribs in a Warren girder arrangement, and were braced to the fuselage by streamlined struts. The aircraft had a fixed tailwheel undercarriage. The Westland IV first flew on 21 February 1929 at which time it was powered by the 95 hp (71 Kw) Cirrus engine. This prototype was registere ...

Spartan Arrow
The Spartan Arrow is a British two-seat biplane aircraft of the early 1930s, built by Spartan Aircraft Limited. History Built as a successor to the company's first design the Simmonds Spartan, the Arrow was a two-seat biplane with a spruce and plywood fuselage. The prototype G-AAWY first flew in May 1930 with Cirrus Hermes II engine. The 13 production aircraft that followed used mainly the de Havilland Gipsy II engine. One aircraft, G-ABBE, was fitted with floats and evaluated as a seaplane in 1931, it was converted back to a landplane and later sold in New Zealand, where it was renumbered as ZK-ACQ. A second aircraft, G-ABHD, was sold to Australia where it was renumbered as VH-UQD. A third aircraft, G-ACHG, was sold to Denmark where it was renumbered as OY-DUK. One aircraft G-ABST was built to test a new air-cooled Napier engine (later knowns as the Javelin). The second prototype G-AAWY was also used by Cirrus Aero Engines as an engine test bed.

Simmonds Spartan
The Simmonds Spartan is a 1920s British two-seat biplane trainer/tourer aircraft built by Simmonds Aircraft Limited. History Not happy with the high cost of manufacturing light aircraft, O.E. Simmonds designed and built a wooden two-seat biplane in 1928. To reduce maintenance costs all four wings and ailerons were the same; this allowed one spare wing to be used in any position. Powered by a Cirrus III, the prototype G-EBYU first flew in time to enter the King's Cup Air Race of 1928. The aircraft was flown to the Berlin Aero Show on 24 October 1928, a non-stop flight of 7 hours and 10 minutes. Production began at Woolston, Hampshire, with the final assembly and test flying at Hamble Aerodrome. Forty-nine aircraft were built, many for export, with New Zealand customers buying the most. At home 12 were delivered to the National Flying Services for use as trainers. Three aircraft were operated on floats in Fiji. Although not as famous as other aircraft of the period, one aircraft ...

Klemm L
The Klemm Leichtflugzeugbau GmbH ("Klemm Light Aircraft Company") was a German aircraft manufacturer noteworthy for sports and touring planes of the 1930s. The company was founded in Böblingen in 1926 by Dr. Hanns Klemm, who had previously worked for both Zeppelin and the Daimler Aircraft Company. History While working at Daimler, Klemm had developed his ideas for a light aircraft, to be made of wood for strength and lightness. It should be easy to manufacture, aerodynamically efficient with low mass and wing loading, for which a low-powered engine would be sufficient. Klemm's first design, the Daimler L.15, was a light aircraft with a single 7.5 hp (5.5 kW) Indian motorcycle engine. This aircraft flew in early 1919, although a 12 hp (8.8 kW) Harley-Davidson engine was used instead of the originally-envisioned engine. Klemm then designed a squared-off version of the cylindrical fuselage of the L.15, which could be more easily built, which he designated the ...

Koolhoven FK
N.V. Koolhoven was an aircraft manufacturer based in Rotterdam, Netherlands. From its conception in 1926 to its destruction in the Blitzkrieg in May 1940, the company remained the second major Dutch aircraft manufacturer (after Fokker). Although many of its aircraft were as unsuccessful economically as they were brilliant from a design standpoint, the company managed to score several 'hits', amongst them the FK-58 single-seat monoplane fighter, the FK-50 twin-engine passenger transport, and the FK-41, built in England under licence by Desoutter. History In 1920, aircraft designer Frederick 'Frits' Koolhoven returned from England to his native Netherlands. The postwar years had not been good to him; the British Aerial Transport Company for which he was chief designer went bankrupt and all other manufacturers were struggling for survival too hard to think of hiring. The Netherlands, Koolhoven hoped, would be better. But there he found that while the Netherlands' new airline KL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emsco B-4 Cirrus
The Emsco B-4 Cirrus was a mid-wing, two-seat trainer built in the US in the late 1920s. Six were built and three variants with more powerful engines flown. Design The two-seat B-4 trainer was a mid-wing monoplane with wings of rectangular plan out to blunted tips. Structurally, the largely wooden wings were based on pairs of box spars and spruce and plywood ribs, with duralumin sheet stiffening the leading edges. The rest of the wing was fabric covered. They were wire-braced from above and below with streamlined wires from pylons within the fuselage to the spars. Its Frise ailerons were inset. The B-4's fuselage was based on a chrome-molybdenum steel frame. It had a American Cirrus III four-cylinder, upright inline engine in the nose with an aluminium firewall and tanks in the wing roots. The two tandem cockpits, fitted with dual controls, were over the wing. The view from the forward cockpit, placed around quarter- chord, was good and the instructor's view from the re ...
