Pobjoy Cataract II
The Pobjoy Niagara is a British seven-cylinder, air-cooled, radial, aero-engine first produced in 1934. The design ran at higher speeds than conventional engines, and used reduction gearing to lower the speed of the propeller. This led to a noticeable off-centre mounting for the propeller. The Niagara was a popular engine for light and experimental aircraft, well regarded due to its small diameter, smooth operation, low noise and innovative engineering.

Moss M
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) ''sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are appr ...

Autogiro Company Of America AC-35
The Autogiro Company of America AC-35 was an early attempt to make a roadable aircraft in the United States during the 1930s. Although it was successfully tested, it did not enter production; a 1960s attempt to revive the aircraft in a non-roadable version also failed to achieve success. Design and development The aircraft design process started in 1935. The Experimental Development Section of the Bureau of Air Commerce contracted the building of a roadable aircraft based around an PA-22 autogyro from ACA's parent company, Pitcairn Autogiro Company. The vehicle could fly at high speed in the air, and drive at up to on the ground with its rotors stowed. Six other companies were contracted to produce a roadable aircraft, but the AC-35 was the only one that met all the requirements. The AC-35 had side-by-side seating with a small baggage compartment. The fuselage was a combination of steel tube in front, and wood construction in the tail with fabric covering overall. The engine w ...

Pitcairn PA-22
The 1933 experimental Pitcairn PA-22 was one of the first wingless autogyros. It was controlled by movement of the rotor plane rather than the usual control surfaces, though initially the much modified lone example retained rudders as a precaution. Design and development The first autogyros, while relying on the rotor for lift, were controlled in flight with ailerons, elevator (aeronautics), elevators and rudders like conventional fixed wing aircraft. The first United States autogyro to dispense with these was the PA-22, which the pilot manoeuvred by altering the rotor plane with a long hanging stick which reached down into the cabin; such designs were termed direct control autogyros. Direct control meant the aircraft could be controlled at the lowest speed at which sufficient lift was available, rather than the higher speeds required for control surface authority. First flown in April 1933, it was first demonstrated in public in Washington D.C., Washington, D.C., on 8 Novembe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hendy Hobo
The Hendy 281 Hobo was a British single-seat light monoplane designed by Basil B. Henderson and built by the Hendy Aircraft Company at Shoreham Airport in 1929. Only one aircraft was built, registered ''G-AAIG'', and first flown in October 1929 by Edgar Percival. It was a small low-wing cantilever monoplane with a fixed tailskid landing gear and powered by a 35 hp ABC Motors Scorpion II engine. It was rebuilt in 1934 with a 90 hp Pobjoy Cataract, mass balance ailerons and a modified landing gear. Operational life Under the ownership of Lord Patrick Stuart''The Ramsey Courier.'' Friday 2 August 1935 (p.4). it was entered in many races in the 1930s and in 1934 won a race between Hatfield and Cardiff at . In the summer months of 1935 the Hendy Hobo was operated out of Hall Caine Airport, Isle of Man. Under the control of Flight lieutenant R. Duncanson, a former Chief Flying Instructor at the London Air Park and who had recently set up a flying school at Hall Caine. The ...

British Klemm Swallow
The B.A Swallow was a British light aircraft of the 1930s. It was a license-built version by the British Klemm Aeroplane Company (which later became known as the British Aircraft Manufacturing Co.) of the German Klemm L.25. A total of 135 were built. Design and development The German aircraft manufacturer Klemm developed a successful low-powered light aeroplane, the Klemm L.25, which first flew in 1927,Smith and Kay 1972 of which over 600 were produced. Several were sold to British owners, where they proved popular, so the British dealer for the L.25, Major E.F Stephen, set up the "British Klemm Aeroplane Company" at London Air Park, Hanworth, Middlesex to produce a version of the L.25 under license. The prototype of the licensed version, known as the B.K.

Spartan Clipper
The Spartan Clipper was a British light touring aeroplane of the 1930s. It was a single-engine, two-seat, low-wing monoplane with a fixed tailwheel undercarriage. Development H.E. Broadsmith designed the Clipper as a two-seater; he employed the outer wings of the Monospar ST-4. Spartan Aircraft Limited built one example at their East Cowes works in 1932. The aeroplane was initially fitted with a 75-hp Pobjoy R motor. Registered ''G-ACEG'' it flew for the first time on 14 December 1932. After modification to undercarriage, cabin glazing and cowling, it received a Certificate of Airworthiness on 29 June 1933. In 1933 the Clipper was raced in the King's Cup Race. In 1938, it was re-engined with a Pobjoy Niagara III of 90-hp, after which it was used as a company hack until 4 May 1942, when it was destroyed in an air raid on Cowes.

Short Scion
The Short S.16 Scion and Scion II were 1930s British two-engine, cantilever monoplanes built by Short Brothers and (under licence) by Pobjoy Airmotors and Aircraft Ltd. in Rochester, Kent between 1933 and 1937. Altogether 22 Scion/Scion II aircraft were built and they provided useful service to operators working from small airstrips/water courses in many parts of the globe, including Europe, the Near and Middle East, Sierra Leone, Papua New Guinea and Australia. Many were impressed into the Royal Air Force during the Second World War, providing pilot ferry services, anti-aircraft co-operation and radar calibration duties. Of the civilian Scions, at least two were still operating in Australia in 1966, one having been re-engined with de Havilland Gipsy Minor engines. Design The Scion and the later Scion II version were high wing cantilever monoplanes with fabric-covered metal wings and fuselage, the latter providing an enclosed cabin for the pilot and 5–6 passengers.

Short Scion Senior
The Short S.22 Scion Senior was a 1930s United Kingdom, British four-engined nine-passenger floatplane built by Short Brothers. Design and development The Scion Senior was developed as an enlarged version of the Short Scion, Scion light transport for nine passengers. Unfortunately, the aircraft failed to win orders from internal airline operators, who had already adopted the De Havilland Dragon and de Havilland Dragon Rapide, Dragon Rapide; instead it proved attractive as a seaplane for survey and river transport purposes overseas, and the first order came from the Irrawaddy River, Irrawaddy Flotilla Co. in Burma, with a promise of further orders if the first seaplane proved satisfactory. So the Scion Senior was designed basically as a seaplane with an alternative land chassis. The first two aircraft, built as floatplanes, were shipped to Rangoon as soon as they had received their Certificate of Airworthiness; the third aircraft was built as a landplane for Shorts to use as a dem ...
