Avro 652
The Avro 652 was a 1930s British light airliner, built by A.V. Roe and Company. It was a twin-engine, low-wing monoplane with a retractable undercarriage, and a tailwheel. Although only two were produced, it formed the basis for the successful Avro Anson. Design and development In 1933, Imperial Airways issued a specification to Avro, for a light airliner to transport four passengers for up to 420 mi (676 km) at a cruising speed of 130 mph (210 km/h). By August 1933, Roy Chadwick's team had produced a design study. This had to be revised when Imperial Airways changed the specification, to enable the machine to fly the Karachi-Bombay-Colombo night mail service. The amended design was accepted, and in April 1934 an order for two aircraft was issued. The first aircraft flew on 7 January 1935, and the type was certificated in March 1935. Operational history On 11 March 1935, the two Avro 652s were delivered to Imperial Airways at Croydon Airport. They served wi ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

1930s British Airliners
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. Events By place Roman Empire * January 1 – Year of the Five Emperors: The Roman Senate chooses Publius Helvius Pertinax, against his will, to succeed the late Commodus as Emperor.

Avro Aircraft
AVRO, short for Algemene Vereniging Radio Omroep ("General Association of Radio Broadcasting"), was a Dutch public broadcasting association operating within the framework of the Nederlandse Publieke Omroep system. It was the first public broadcaster in the Netherlands. In 2014 AVRO merged with fellow broadcaster TROS to form AVROTROS. History On 8 July 1923, Hilversumsche Draadlooze Omroep was launched by the Nederlandsche Seintoestellen Fabriek (in English: Dutch Transmitter Factory) under supervision of Willem Vogt. On 21 July 1923, it provided the very first regular radio broadcast in the Netherlands. In 1927 it changed its name into Algemeene Nederlandsche Radio Omroep (ANRO), followed soon by a merger with Nederlandsche Omroep Vereeniging (NOV). On 28 December 1927, the two merged broadcasters continued as Algemeene Vereeniging Radio Omroep (A.V.R.O., in English: "General Association of Radio Broadcasting"). In 1938, AVRO sponsored what was the strongest chess tournamen ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

List Of Aircraft Of Imperial Airways
Imperial Airways was the early British commercial long-range airline, operating from 1924 to 1939 and principally serving the British Empire routes to South Africa, India, Australia and the Far East, including Malaya and Hong Kong. Passengers were typically businessmen or colonial administrators, and most flights carried about 20 passengers or less. Accidents were frequent: in the first six years, 32 people died in seven incidents. Imperial Airways never achieved the levels of technological innovation of its competitors and was merged into the British Overseas Airways Corporation (BOAC) in 1939. BOAC in turn merged with the British European Airways (BEA) in 1974 to form British Airways. Background The establishment of Imperial Airways occurred in the context of facilitating overseas settlement by making travel to and from the colonies quicker, and that flight would also speed up colonial government and trade that was until then dependent upon ships. The launch of the airline ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Percival Petrel
The Percival Q.6 was a 1930s British communications aircraft built by Percival Aircraft Limited at Luton. Originally, the Percival Q.6 was a civil transport but It was used during the Second World War by the Royal Air Force and Royal Navy as a communications and liaison aircraft. It was a twin-engine, low-wing monoplane with a tailwheel undercarriage. Design and development The Percival Type-Q was Percival's first twin-engine aircraft. It was constructed of wood, with plywood and fabric covering. It had a fixed, tailwheel undercarriage, with faired mainwheels, although four of the production machines would be equipped with retractable undercarriage. Two versions were designed: the Q.4, a four-seat executive transport, and the Q.6, a six-seat feederliner. The Q.4 was not built. The prototype Q.6, registration ''G-AEYE'', first flew on 14 September 1937 at Luton Airport. Production started in 1938, and the first production aircraft, registered ''G-AFFD'', was delivered to Sir Ph ...

Bristol 142
The Bristol Type 143 was a British twin-engine monoplane aircraft designed by Frank Barnwell of the Bristol Aeroplane Company. Developed alongside the more famous Bristol Type 142, which was developed into the Blenheim light bomber, it used the same wing design and employed the same advanced (for the day) design features such as stressed skin, flaps, and retractable undercarriage. The engine it was designed to use never entered production and only a single prototype was manufactured, Design and development Like the better-known Type 142 the Type 143 arose from the unbuilt Bristol Type 135 proposal for a civil twin-engine light transport aircraft. This was a low-wing twin-engined monoplane, seating six people and a crew of two, first sketched out by Frank Barnwell, with the intention of using the smaller of the two engines then being developed by Roy Fedden, the Aquila I. Although the manufacture of a second Aquila was authorised, nothing was done about the construction of an ...

Airspeed Envoy
The Airspeed AS.6 Envoy was a twin-engined light transport aircraft designed and produced by the British aircraft manufacturer Airspeed Ltd. The Envoy originated as a heavier twin-engine derivative of Airspeed's Courier light transport aircraft. Sharing much of its design with this earlier aircraft, it was relatively easy to develop; confidence in the project was so high that within a week of the prototype's maiden flight, it was performing as a display aircraft to the public. Quantity production of the Envoy had been initiated even before this first flight. Early on, Airspeed worked closely with the British engine manufacturer Wolseley Motors as both a key supplier and early custom of the Envoy; development subsequently branched out to a wide variety of engines and configurations. The majority of Envoys were produced by Airspeed at their facility at Portsmouth Aerodrome, Hampshire. The type was also produced overseas in Japan by Mitsubishi following the acquisition of a lic ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Armstrong Siddeley Cheetah
The Armstrong Siddeley Cheetah is a seven-cylinder British air-cooled aircraft radial engine of 834 cu in (13.65 L) capacity introduced in 1935 and produced until 1948. Early variants of the Cheetah were initially known as the Lynx Major.Lumsden 2003, p.74. The Cheetah was used to power many British trainer aircraft during World War II including the Avro Anson and Airspeed Oxford. Design and development The Cheetah was developed from the earlier Lynx using the increased bore cylinders from the Armstrong Siddeley Panther but the engine retained the stroke of the Lynx. Initially only direct-drive variants were produced with later engines being made available with propeller reduction gear of various ratios. Superchargers were also available for later variants, both geared and directly driven by the crankshaft. The basic design of the Cheetah remained unchanged from its introduction in 1935 to the last examples built in 1948. It was the first engine of its type to be certified ...
