The Perry Beadle T.1 was a single-seat, single engine biplane built and flown in the United Kingdom in 1913. In 1914 it flew with a more powerful engine and other modifications as the Perry Beadle T.2, which was acquired by the Royal Navy Air Service at the outbreak of World War I.

Design and development

Perry, Beadle & Co. was formed by E.W. Copland Berry, a pilot, and F.P. Hyde Beadle, a technician, who were at the Royal Aircraft Factory, Farnborough together in 1912. Their first product was the 1913 T.1, a single-seat tractor biplane modified the following year into the more powerful T.2. The T.1 and T.2 are the only Perry Beadle types known to have flown. [1]

The T.1 was a biplane with wings of equal span, constant chord and no stagger or sweep. It had an essentially two bay wing structure, though a third set of simple parallel interplane struts on each wing, close to the fuselage, took the place of cabane struts. Parallel chord ailerons were fitted only to the upper wing. The fuselage was mounted between the wings, with gaps both above and below; the interplane gap was wide at about 5 ft 9 in (1.75 m). The fuselage was flat sided and tapered to the tail, but had a curved decking which sloped down both fore and aft from the under wing cockpit. This improved the pilot's forward view; a cut-out in the trailing edge of the upper wing aided his upward vision. [1]

At the rear, the T.1 had a conventional tailplane and elevators but there was no fixed fin, only a deep rudder which ran between and well below the elevators to the struts that also carried the tail skid. The main wheels were sprung on a pair of forward skids. In the nose a 25 hp (19 kW) inverted Y Anzani 3-cylinder engine drove a two-bladed propeller. [1]

The T.1 was built and flown at Beaulieu, Hampshire in 1913, with at least one flight from there to Cowes, a distance of about 8 miles (13 km). In the following May a more powerful version with increased wing area and smaller interplane gap came to Brooklands, designated the T.2. The extra power came from a 6-cylinder, two row Anzani 6 radial which produced 45 hp (34 kW). The extra wing area was achieved by extending the upper wing by about 5 ft (1.5 m) on each side, the overhang braced by extra pairs of outward leaning struts. The ailerons were now tapered. The interplane gap was decreased to 4 ft 9 in (1.45 m) by attaching the lower wing to the bottom of the fuselage. The undercarriage was simplified by removing the skids, leaving a simple single axle supported by pairs of inverted V struts. [1]

The T.2 flew from Brooklands on 26 June 1914, piloted by Copland Berry. It was later flown by others and, when war began, was requisitioned into the RNAS with serial 1322. It was destroyed at Hendon the following March. [1]

Roe IV Triplane

The Roe IV Triplane was an early British aircraft designed by Alliott Verdon Roe and built by A.V. Roe and Company. It was first flown in September 1910.

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.

Avro 500

The Avro Type E, Type 500, and Type 502 made up a family of early British military aircraft, regarded by Alliott Verdon Roe as his firm's first truly successful design. It was a forerunner of the Avro 504, one of the outstanding aircraft of the First World War.

Handley Page Type G

The Handley Page Type G was a two-seat British biplane, designed by Handley Page that first flew in 1913. Only one was built.

Farman Sport

The Farman FF 65 Sport was a French built light biplane, with a single engine and tandem seats, intended for sport and touring. First flown in 1919, it achieved modest sales at home and abroad in the early 1920s. Two unusual modifications produced a biplane glider and a low aspect ratio parasol wing machine.

Caproni-Pensuti triplane

The Caproni-Pensuti 2 was a small single-engine sports triplane aircraft designed and built in Italy just before the end of World War I. It had a wingspan of only 4.0 m or a little over 13 ft.

Kondor D 6

The Kondor D 6 was a prototype German biplane fighter aircraft flown in 1918. In the interests of better upward vision for the pilot, its upper wing was in two halves, separated over the central fuselage. Its development was soon abandoned.

Caudron Type A Early French fixed-wing aircraft

The Caudron Type A was the first successful aircraft built by René Caudron and his brother Gaston. During 1910 the Caudron brothers were briefly associated with the Société Anonyme Français d'Avaiation (S.A.F.A.), and an example of the type was exhibited at the 1910 Paris Aero Salon as the S.A.F.A. Biplane.

The Gerner G.I or Gerner G I, was a small, low powered, two seat biplane of steel tube construction, built in Germany in 1928. Only one was produced but the design led to the more successful Gerner G II R.

Caudron C.27

The Caudron C.27 was a French biplane, a two-seat basic trainer which also competed successfully in the 1920s.

Caudron C.68

The Caudron C.68 was a two-seat French training and touring aircraft, built in the early 1920s, which attracted interest at the time because of its simple and fast wing folding arrangement. Only a few were produced.

Caudron C.67

The Caudron C.67 was a simple single seat biplane with a low powered engine. It was built and flown in France in 1922.

Caudron C.25

The Caudron C.25 was a large, three-engined, biplane airliner, designed and built in France soon after the end of World War I. Its enclosed cabin could accommodate up to eighteen passengers.

Caudron Type O

The Caudron Type O was a French single seat air racing biplane first flown in 1914.

The Caudron Type B was a 1911 development of the earliest Caudron type, the Caudron Type A, with a nacelle style fuselage and more powerful engine. Initially an equal span biplane, it was modified into a sesquiplane.

The Caudron Type B Multiplace was a large French biplane designed to carry up to five passengers in a cross country time trial of 1912. It was destroyed early in the event.

Caudron Type D

The Caudron Type D was a French pre-World War I single seat, twin-boom tractor biplane, a close but slightly smaller relative of the two seat Caudron Type C. More than a dozen were completed, one exported to the United Kingdom, where they may also have been licence built, and three to China.

The Caproni Ca.61 was an Italian heavy day bomber aircraft of 1922. It was the final development of the Caproni three engine, twin boom biplane types developed during World War I, but it was not put into production.

Holland H.1

The VIH Holland H.1 was a Dutch two seat, low-powered biplane. Only one was built.

Skraba S.T.3

The Skraba S.T.3 was a two-seat Polish biplane built in 1928. It was the first all-metal aircraft designed in Poland; only one was completed.
