Cierva CL.20
The Westland CL.20 (aka Cierva-Lepère C.31) was a two-seat autogyro designed and built by Westland Aircraft between 1934 and 1938. One flying prototype and six airframes were built, which had control problems and insufficient lift. Before these problems could be solved the programme was abandoned and the prototype was scrapped in 1938. Development Before the Westland C.29 had proven to be a failure, "Teddy" Petter sought to design another cabin autogyro in collaboration with George Lepère, a French autogyro designer with the Lioré et Olivier aircraft company. The initial design was by Georges Lepère in association with the Cierva Autogiro Company and was based on the Cierva-Lepère C.L. 10B. Detailed design was by Westland's Arthur Davenport and Petter. Construction was completed in December 1934 and in January 1935 taxi-ing trials were carried out at Yeovil by Harald Penrose, after which it was transported to the Cierva flight test centre at Hanworth Aerodrome, where J ...

Harald Penrose
Harald Penrose, O.B.E, CEng, F.R.Ae.S, A.M.I.N.A (12 April 1904 – 31 August 1996) was the chief test pilot at Westland Aircraft between 1931 and 1953, a naval architect, and an aviation author. His flying experience ranged from man carrying kites before the First World War to early jet fighters and helicopters. He designed, built and flew his own glider in the 1930s, designed 36 boats and yachts, and wrote many books describing his flying career and the history of British aviation. Early life Harald James Penrose was born at 103 Park Street Hereford on 12 April 1904, the son of James Penrose, an Inland Revenue clerk and his wife, Elizabeth Alice. His fascination with manned flight started at an early age when his father showed him pictures of Bleriot's monoplane. He first flew aged 7 in a man-lifting kite at the dizzying height of 10 ft. His first powered flight was in 1919, in a modified three seat Avro 504K, piloted by Alan Cobham. When he left school in 1920 he ...

Pobjoy S Niagara III
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. Variants ;Niagara I :Bore/stroke 77 x 87 mm (3.03 x 3.43 in), swept volume 2,835 cc (173 cu in). Compression 6.25:1, gearing 0.47:1. Normal continuous power 84 hp (63 kW) at 3,200 rpm at sea level. ;Niagara II :Bore/stroke 77 x 87 mm (3.03x3.43 in), swept volume 2,835 cc (173 cu in). Compression 6.0:1, gearing 0.39:1.

Pobjoy Airmotors
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. History Douglas Rudolf Pobjoy started in the engine business working with Roy Fedden at Cosmos Engineering just after the end of World War I. Cosmos went bankrupt shortly after the war, and its assets were picked up by the Bristol Aeroplane Company, where Fedden would go on to produce a line of extremely successful engines. Pobjoy also spent time in the RAF as an education officer. Here he met Flt. Lt. Nicholas Comper who went on to design the Comper Swift, that would later fly from London to Australia in 9 days 2 hours. Pobjoy partnered with Parnall to develop an engine for the Swift. Although they felt that a cast-block inline engine like the ones being produced by Cirrus and de Havilland would always be less expensive, they nevertheless selected the radi ...

Westland Aircraft
Westland Aircraft was a British aircraft manufacturer located in Yeovil, Somerset. Formed as a separate company by separation from Petters Limited just before the start of the Second World War, Westland had been building aircraft since 1915. During the war the company produced a number of generally unsuccessful designs, but their Lysander would serve as an important liaison aircraft with the Royal Air Force. After the war the company focused on helicopters, and was merged with several other British firms to create Westland Helicopters in 1961. History Foundation In 1915 the Westland Aircraft Works was founded as a division of Petters in response to government orders for the construction under licence of initially 12 Short Type 184 seaplanes, followed by 20 Short Admiralty Type 166. Orders for other aircraft followed during First World War, including the Sopwith 1½ Strutter, the de Havilland designed Airco DH.4, Airco DH.9 and Airco DH.9A and the Vickers Vimy. The name ...

Arthur Davenport (aeronautical Engineer)
Arthur Davenport F.R.Ae.S (9 July 1891 for Yeovil, Somerset, TNA ref: RG101/7054A/018/1 Letter Code: WOVP – 31 August 1976) was a British aircraft engineer working for Westland Aircraft in Yeovil, Somerset. When the Westland Aircraft Works was created by the Petter twins in 1915, Arthur was one of the first draughtsman to be recruited from Petter's Ltd. He was chief designer from 1919, working under the direction of Teddy Petter from May 1934 until 1944, when Petter left (to join English Electric) and Davenport became technical director. According to Harald Penrose, he was made the scapegoat for the late delivery of the Wyvern and headed into retirement in March 1952. In the 1920s, when most aircraft were biplanes, Arthur was a strong proponent of the monoplane. Most of his monoplane designs were high-winged or parasol, culminating in the Lysander. During his career he was involved in the design of the following fixed-wing aircraft. * Westland Limousine Chief draughtsman * ...
