De Havilland Swallow Moth
The de Havilland DH.81 Swallow Moth was aimed at the low-cost sporting aircraft market during the Great Depression. It was a single-engined two-seat low-wing monoplane; only one was built. Development The DH. 81 Swallow Moth was a low-wing cantilever monoplane. This arrangement and its plywood-covered fuselage and closely cowled 80 hp (60 kW) inline Gipsy IV engine gave it a very clean aerodynamic look. The wings carried ailerons that were horn-balanced at the wingtips and the empennage was of characteristic de Havilland form, with a balanced rudder. There was separate tandem seating for two, initially open, but later enclosed with a one-piece hinged cabin top. With this enclosure the aircraft was called the DH.81A and the top speed increased by 12 mph (19 km/h). The main undercarriage was simple, the legs reaching to mid-fuselage in front of the leading edge of the wing, with bracing struts fore and aft to the keel; the later Leopard Moth used a simi ...

De Havilland Aircraft
The de Havilland Aircraft Company Limited () was a British aviation manufacturer established in late 1920 by Geoffrey de Havilland at Stag Lane Aerodrome Edgware on the outskirts of north London. Operations were later moved to Hatfield in Hertfordshire. Known for its innovation, de Havilland was responsible for a number of important aircraft, including the Moth biplane which revolutionised aviation in the 1920s; the 1930s Fox Moth, a commercial light passenger aircraft; the wooden World War II Mosquito multirole aircraft; and the pioneering passenger jet airliner Comet. The de Havilland company became a member of the Hawker Siddeley group in 1960, but lost its separate identity in 1963. Later, Hawker Siddeley merged into what is eventually known today as BAE Systems, the British aerospace and defence business. The de Havilland name lives on in De Havilland Canada, which owns the rights to the name and the aircraft produced by de Havilland's former Canadian subsidiary, incl ...

Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland Leopard Moth
The de Havilland DH.85 Leopard Moth is a three-seat high-wing cabin monoplane designed and built by the de Havilland Aircraft Company in 1933. Design and construction It was a successor to the DH.80 Puss Moth and replaced it on the company's Stag Lane and later Hatfield production lines. It was similar in configuration to the earlier aircraft, but instead of a fuselage with tubular steel framework, a lighter all-plywood structure was used which allowed a substantial improvement in range, performance and capacity on the same type of engine. The pilot is seated centrally in front of two side-by-side passengers and the wings can be folded for hangarage. Operational history The prototype first flew on 27 May 1933 and in July won the King's Cup Race at an average speed of 139.5 mph (224.5 km/h), piloted by Geoffrey de Havilland. A total of 133 aircraft were built, including 71 for owners in the British Isles, and 10 for Australia. Other examples were exported to France ...

Stag Lane Aerodrome
Stag Lane Aerodrome was a private aerodrome between 1915 and 1933 in Edgware, north London, UK. History The land for an aerodrome was purchased by the London & Provincial Aviation Company (Warren and Smiles - Michael Geoffrey Smiles of Bonnington died in 1921) in October 1915. The company used the aerodrome for flying training during the First World War. London & Provincial ceased flying in July 1919 after a dispute with Department of Civil Aviation (see United Kingdom Civil Aviation Authority), which refused them a licence. Stag Lane became the main base of The de Havilland Aircraft Company Limited in 1920 and they purchased the freehold in 1922. Former wartime aircraft were refurbished in the early years, and the company designed and built large numbers of aircraft at Stag Lane in the 1920s and early 1930s. In 1934 the company moved to a larger factory and airfield at Hatfield Aerodrome, Hatfield, Hertfordshire. Stag Lane Aerodrome was sold for housing development in 1933, ...

United Kingdom Aircraft Test Serials
United Kingdom aircraft test serials are used to externally identify aircraft flown within the United Kingdom without a full Certificate of Airworthiness. They can be used for testing experimental and prototype aircraft or modifications, pre-delivery flights for foreign customers and are sometimes referred to as "B" class markings. 1930s An initial set of markings was introduced in 1929, each company was allocated a letter to which would follow a number, sometimes with a hyphen or a gap between. For example, A was allocated to the Armstrong Whitworth Aircraft and ''A 1'' was used in March 1930 on an Armstrong Whitworth Starling. Sometimes Hawker and Vickers would also add the letters PV to the markings to indicate a private venture (that is a type in development not paid for by the Air Ministry). 1940s The presentation was changed to look like a military serial for security reasons during the Second World War. For example, the prototype de Havilland Mosquito was allocated test ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland Moth Minor
The de Havilland DH.94 Moth Minor was a 1930s British two-seat tourer/trainer aircraft built by de Havilland at Hatfield Aerodrome, England. With the start of the second world war production of the Moth Minor was moved to de Havilland Australia at Bankstown Aerodrome, Australia. Design and development The Moth Minor was designed as a low-wing monoplane to replace the biplane Moth series, and was intended to give similar performance with less power, and without the need for rigging of the biplane's tensioners and struts. Its predecessor was the DH.81 Swallow Moth monoplane of 1931, of which only one was built. The wooden prototype of the DH.94 was first flown by Geoffrey de Havilland on 22 June 1937 at Hatfield Aerodrome. Production started and nearly 100 examples had been built by the outbreak of the Second World War. With a selling price of only £575 the Moth Minor was popular with flying clubs keen to acquire modern monoplanes. Nine aircraft were specially built with hin ...

De Havilland Gipsy
The de Havilland Gipsy is a British air-cooled four-cylinder in-line aircraft engine designed by Frank Halford in 1927 to replace the ADC Cirrus in the de Havilland DH.60 Moth light biplane. Initially developed as an upright 5 litre (300 cubic inch) capacity engine, later versions were designed to run inverted with increased capacity and power. The Gipsy went on to become one of the most popular sport aircraft engines of the inter-war period and was the engine of choice for various other light aircraft, trainers, liaison aircraft and air taxis, British as well as foreign, until long past World War II. Apart from helping to establish the de Havilland Aircraft Company as a manufacturer of light aircraft, it also established the company as an engine manufacturer in its own right. Gipsy engines remain in service powering vintage light aircraft. Design and development Just like the ADC Cirrus, the Gipsy was born as a collaboration between aircraft manufacturer Geoffre ...

1930s British Sport Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
