The Short Sporting Type Seaplane was a single-engined biplane seaplane which first flew in 1919, Shorts' first post-World War I aircraft. [1] Originally designed to a Royal Air Force (RAF) specification [1] issued during the war for two training seaplanes, three aircraft were produced as a commercial venture. Only the first was sold, the other two being cannibalised for parts and then scrapped in 1924.

This design is often referred to as the Short Shrimp although this name was applied only to the first Sporting Type.

Design

The Sporting Type was designed to meet RAF specification number RAF XXXII. [1] It was a four-seat, single-engined biplane with twin wooden floats mounted on wire-braced struts below the fuselage. It had two cockpits, the forward cockpit for the pilot and a passenger sitting in tandem, the other for two passengers sitting abreast; the rear cockpit could also function as cargo room, increasing the aircraft's operational flexibility. The fuselage was of semi-monocoque plywood construction with a fabric fairing.

The upper and lower wings were of equal span and chord; on the first aircraft (named Shrimp) the lower wing had a slight dihedral, while the upper wing was flat. On the two later aircraft, both wings had equal dihedral. All three were fitted with folding wings [2] (which Shorts had developed and patented in the years 1913 -1915 [3] ).

In plan view, the twin-mainfloats, like those of the Short N.2B, were square-fronted with a slight increase in beam from front to rear, while the stern tapered to a point like a mitred arch. They had a concave bottom (the edges were protected by metal strips [4] ) and a sharp step at approximately 3/4 length; a tailfloat was fitted to the fuselage below the conventional tailplane. Attached to the rear of the tailfloat was a taxying rudder, with an additional drop-plate which improved steering on water, and which, thanks to the hinged mounting at the forward end, would rise up into its recess in the tailfloat on contact with the ground when beaching. Wingtip floats were deemed unnecessary. A detail drawing, which appeared in Flight Magazine in 1920, showed the empennage and tailfloat assembly, including the hinged rudder drop-plate. [5]

There was also provision for the attachment of beaching wheels: Each float had a watertight transverse tube, to which a mainwheel could be fitted, and there was a socket for a detachable swivelling tailwheel at the rear of the tailfloat, just forward of the taxying rudder. A side view photograph of the Sporting Type (taken at Olympia in July 1920), showing the port beaching-wheel in place, was published in Flight Magazine. [6]

Development

The first of the three Sporting Types, (Shrimp), was powered by a Beardmore 160 hp (119 kW) engine. [1] Registered G-EAPZ, it was first flown on 10 December, 1919 by test pilot J.L. Parker. [7] Shortly afterwards it was bought by the Australian Lebbeus Hordern, who learned to fly in it. Having had the Beardmore engine replaced by the 230 hp (172 kW) Siddeley Puma, he shipped it to Australia in 1921, where it was reregistered as G-AUPZ in June 1922 (later VH-UPZ). The Shrimp was used in two surveys of the coast of New Guinea, during which a film was made which was later shown in the UK under the name "Pearls and Savages". It crashed in Sidney Harbour in January 1923 and was written off. [2] [8]

The two further Sporting Types remained unnamed. The second was fitted first with the Puma engine and flew for the first time on 28-07-1920, after having been displayed in the same month at London's Olympia exhibition centre. [6] It was found by Parker to have greater lateral stability than the Shrimp, due to the dihedral on both wings. Following an accident in September of the same year, the Puma was replaced by a 300 hp (224 kW) Hispano-Suiza engine. [2] The third aircraft, which first flew on 21-01-1921, was fitted with the Puma engine. Neither aircraft was sold and both were taken out of service and cannibalised for engines and instruments before being scrapped in 1924. [9]

Short Type 184

The Short Admiralty Type 184, often called the Short 225 after the power rating of the engine first fitted, was a British two-seat reconnaissance, bombing and torpedo carrying folding-wing seaplane designed by Horace Short of Short Brothers. It was first flown in 1915 and remained in service until after the armistice in 1918. A Short 184 was the first aircraft to sink a ship using a torpedo, and another was the only British aircraft to take part in the Battle of Jutland.

Short Bomber

The Short Bomber was a British two-seat long-range reconnaissance, bombing and torpedo-carrying aircraft designed by Short Brothers as a land-based development of the very successful Short Type 184.

Short Springbok

The Short Springbok was a two-seat, all-metal reconnaissance biplane produced for the British Air Ministry in the 1920s. All together six aircraft of the Springbok design were built but none entered service with the armed forces.

Short Knuckleduster

The Short R.24/31 was a British twin-engined, high-wing cantilever gull winged monoplane flying-boat designed and built by Short to Air Ministry specification R.24/31 for a "General Purpose Open Sea Patrol Flying Boat". The contract also specified the use of the experimental Rolls-Royce Goshawk engine. The Saunders-Roe London and the Supermarine Stranraer competed successfully for this contract.

Avro Type D

The Avro Type D was an aircraft built in 1911 by the pioneer British aircraft designer A.V. Roe. Roe had previously built and flown several aircraft at Brooklands, most being tractor layout triplanes. The Type D was his first biplane.

Short Folder

Short Folder is a generic name often applied to several different Short Brothers' aircraft types designed and built prior to and during World War I. Short Brothers developed and patented folding wing mechanisms for ship-borne aircraft from 1913; the wings were hinged so that they folded back horizontally alongside the fuselage, reducing the storage space required for stowing them aboard ship.

Short Crusader British racing seaplane

The Short Crusader also called the Short-Bristow Crusader and Short-Bristol Crusader was a British racing seaplane of the 1920s, built by Short Brothers to compete in the 1927 Schneider Trophy race.

The Short Type 166 was a 1910s British two-seat reconnaissance, bombing and torpedo-carrying folder seaplane, designed by Short Brothers.

Bristol Type 133 Monoplane prototype

The Bristol Type 133 was a single-seat, single-engine monoplane fighter armed with four guns, using stressed-skin construction and with a retractable undercarriage. It was built by The Bristol Aeroplane Co. to meet Specification F.7/30. The single example crashed before the trials commenced.

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.

Handley Page H.P.31 Harrow

The Handley Page H.P.31 was a two-seat single-engined biplane built to a British specification for a carrier-based torpedo bomber and reconnaissance aircraft. After trials, the Blackburn Ripon was preferred, though the Harrow played a significant role in the development of automatic slots.

Handley Page Type E

The Handley Page Type E was a two-seat, single-engined monoplane intended as a demonstrator. Though only one was built, it flew successfully from 1912 to 1914, carrying several hundred passengers and flying several thousand miles.

Parnall Possum

The Parnall Possum was an experimental triplane, with a single, central engine driving wing-mounted propellers via shafts and gears. Two of these British aircraft were built in the mid-1920s.

The Short S.6 Sturgeon was a prototype single-engined biplane naval reconnaissance aircraft, built to an Air Ministry specification but mostly intended as a demonstrator of the corrosion resistance of duralumin aircraft structures. Two were made.

Short Gurnard

The Short Gurnard was a single-engined two-seat biplane naval fighter, built in the United Kingdom to an Air Ministry specification in 1929. It failed to win production orders and only two flew.

Short S.41

The Short S.41 was a British single-engined biplane built for the Royal Navy in 1912. Capable of being operated either on wheels or floats, it was successful enough for a further two similar aircraft to be built, with the type remaining in use until the early years of the First World War.

The Short S.45 — also known as the Short T.5 after its naval serial number — was a training biplane built for Britain's Royal Navy by Short Brothers in 1912. It was the forerunner of another three identical aircraft delivered to the Royal Navy and Royal Flying Corps during 1912 and 1913. The Royal Naval Air Service was still operating the type when World War I broke out in 1914.

The Bristol-Burney seaplanes were a pair of experimental seaplanes produced by a collaboration between Lt. Dennistoun Burney and the Bristol and Colonial Aeroplane Company during 1912–14. The aircraft, neither of which was successfully flown, featured a novel hydroplane undercarriage. Although not a success, their development was the basis of Burney's later invention of the paravane.
