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. [1]

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. The tail unit comprised a cantilever tailplane with a single fin and rudder. The prototype aircraft was powered by two 80 hp (60 kW) Pobjoy R radial engines; the production aircraft however were fitted with the 90 hp (67 kW) Pobjoy Niagara III radial engines. The engines in the Scion were mounted with thrust-lines below the chord-line of the wings; in the Scion II they were raised so that the thrust-lines were aligned with the chord-line, to avoid trim changes in pitch with changes in power. Both the Scion and the Scion II were produced as either landplanes or floatplanes, the majority as landplanes (see the table below). On the landplanes the landing gear comprised a single wheel on each side of the fuselage, mounted on a vertical coil-spring and oleo leg inboard of the engine; there was a small castoring tailwheel mounted below the rear end of the fuselage.

The Scion was developed as a light transport for 5–6 passengers. The first flight of the prototype aircraft (G-ACJI) took place on 18 August 1933, piloted by Shorts' Chief Test Pilot John Lankester Parker. The first production aircraft (G-ACUV) was flown at the SBAC's airshow at Hendon in 1934. In 1935 the fifth production model was built as the revised model Scion II; the major improvement was the repositioning of the two engines as noted above; other changes included the provision of 6 passenger seats as standard (on the original Scion there was a folding seat for a sixth passenger if needed), an improved windscreen and better cabin windows. During the production of the Scions the company had opened a new factory at Rochester Airport and all Scion IIs were manufactured there, initially by Shorts, later by Pobjoy, first under licence and later under Shorts' ownership.

G-ADDR, the fifth Scion II, was retained by Shorts as an experimental testbed aircraft, and it was on this aircraft (temporarily designated M.3) that a scale wooden model of the slender wings (with Gouge flaps) for the later Short Empire boats was tested, the first flight in this configuration being conducted by Lankester Parker on 6 August 1935. With these flaps fitted it was tested at the Royal Aircraft Establishment, which found that the Gouge flap decreased distance to take-off and stalling speed, among other improvements. [3] Further work with standard wings was carried out; one flight from Rochester Airport, with experimental full-span flaps incorporating retractable spoilers instead of ailerons, was made on 22 July 1936; this idea proved unworkable, Lankester Parker having to draw on his considerable experience to coax the aircraft around on a single circuit before landing safely. The standard wing was refitted and the aircraft continued with Shorts in this configuration until it was impressed into military service in 1940, an operational usage experienced by 14 of the 22 Scion/Scion II aircraft.

G-AEZF, built by Pobjoy and first flown in December 1937, was originally operated as a floatplane by Elders Colonial Airways in Sierra Leone, between Bathurst (Gambia) and Freetown, and was returned to Shorts in 1939 and converted into a landplane in 1941. After operating for the company for another six years it was eventually sold on to Air Couriers Ltd. in 1947, [4] after which it changed hands between private owners several times before finally ending up at Southend airport.

A larger 9-passenger enlarged version of Scion was produced as the Short S.22 Scion Senior.

Short Brothers plc, usually referred to as Shorts or Short, is an aerospace company based in Belfast, Northern Ireland. Shorts was founded in 1908 in London, and was the first company in the world to make production aeroplanes. It was particularly notable for its flying boat designs manufactured into the 1950s.

Short Empire

The Short Empire was a medium-range four-engined monoplane flying boat, designed and developed by Short Brothers during the 1930s to meet the requirements of the growing commercial airline sector, with a particular emphasis upon its usefulness upon the core routes that served the United Kingdom. It was developed and manufactured in parallel with the Short Sunderland maritime patrol bomber, which went on to serve in the Second World War; a further derivative that was later developed was the piggy-back Short Mayo Composite.

Short S.8 Calcutta

The Short Calcutta or S.8 was a civilian biplane airliner flying boat made by Short Brothers.

Junkers A50

The Junkers A50 Junior was a German sports plane of the 1930s.

Pobjoy Airmotors and Aircraft was a British manufacturer of small aircraft engines. The company was purchased by Short Brothers shortly before the start of World War II, production continuing until the end of the war.

Rochester Airport is an operational general aviation aerodrome located 1.5 nautical miles south of Rochester, Medway, South East England, with the River Medway 1.5 NM from the end of runway 34, 3.4 mi (5.5 km) from Chatham and its Historic Dockyard and the Medway area.

Short S.26

The Short S.26 G-class was a large transport flying boat designed and produced by the British aircraft manufacturer Short Brothers. It was designed to achieve a non-stop transatlantic capability, increasing the viability of long distant services/duties.

Short Mayo Composite

The Short Mayo Composite was a piggy-back long-range seaplane/flying boat combination produced by Short Brothers to provide a reliable long-range air transport service to North America and, potentially, to other distant places in the British Empire and the Commonwealth.

Short Scion Senior

The Short S.22 Scion Senior was a 1930s British four-engined nine-passenger floatplane built by Short Brothers.

Short Kent

The Short S.17 Kent was a British four-engined 15-seat biplane luxury flying boat airliner, designed and built by Shorts to meet a requirement from Imperial Airways for an aircraft with greater range than the Short Calcutta. The new aircraft was to have sufficient range to fly the stage from Mirabella, Crete, to Alexandria in Egypt without the need for refuelling stops in Italian colonial territory due to a political row which had led the Italian Government to ban British aircraft from its ports.

General Aircraft Fleet Shadower

The General Aircraft G.A.L.38 Fleet Shadower was a British long-range patrol aircraft design of the immediate pre-Second World War period. The Fleet Shadower was a highly specialized aircraft intended to follow enemy naval task forces over long times and radio back position information. However, the concept produced an ungainly and ultimately unsuccessful type. The Airspeed Fleet Shadower, built to the same requirement, also did not progress past the prototype stage.

Pobjoy Niagara

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.

General Aircraft Monospar 1930s British utility aircraft

The General Aircraft Monospar was a 1930s British family of touring and utility aircraft built by General Aircraft Ltd (GAL).

Keystone Pronto 1920s US mail plane design

The Keystone K-55 Pronto was a mail plane developed in the United States in the late 1920s.

Short Valetta 1930s British passenger monoplane

The Short S.11 Valetta was a 1930s British passenger monoplane designed and built by Short Brothers at Rochester.

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.

The Gouge flap, invented by Arthur Gouge of Short Brothers in 1936, allowed the pilot to increase both the wing area and the chord of an aircraft's wing, thereby reducing the stalling speed at a given weight. This provided the benefit of a shorter takeoff distance for a given load, a shorter distance to achieve a given height and a lower takeoff speed. This type of flap, in spite of its use on successful aircraft such as the Short Sunderland and the Short Stirling, was limited to use on aircraft produced by Short Brothers.

The Pobjoy Pirate was a three-seat, high-wing monoplane designed to compete with the de Havilland Leopard Moth using a low power but light Pobjoy radial engine. Flight tests showed the Pirate to be uncompetitive and its development was rapidly abandoned.

Hamilton H-47

The Hamilton H-45 and H-47 were six-passenger-seat, all-metal, high-wing monoplanes powered by single Pratt & Whitney radial engines. They were built for passenger and mail-carrying work in the US in the late 1920s.

Gwinn Aircar

The Gwinn Aircar was a single-engined biplane with a cabin for two, designed in the US as a safe and simple private aircraft. Lacking a rudder, it had several unusual control features as well as an early tricycle undercarriage. Development was abandoned after a crash in 1938.
