17-498: Redrup is a surname. Notable people with the surname include: Charles Benjamin Redrup (1878–1961), British aeronautical engineer and inventor Ronald Redrup (1935–2013), British boxer See also [ edit ] Redrup v. New York , 1967 lawsuit [REDACTED] Surname list This page lists people with the surname Redrup . If an internal link intending to refer to

34-437: A combined static pitch increase to all rotor blades, which is known as collective pitch. Nutating flowmeters and pumps have similar motions to the wobble of a swashplate, but do not necessarily transform the motion to a reciprocating motion at any time. Active electronically scanned array (AESA) radars are flat plates that can scan up to sixty degrees in any direction from directly ahead of them. By mounting an AESA radar on

51-625: A number of journals at the time. Later models of the motorcycle dispensed with the pedals, and the engine was lowered to improve the centre of gravity. No known models of the engine exist but a similar Redrup 1912 rotary aircraft engine is in the Museum of Science and Industry in Manchester , and Redrup Radial, later engines designed and built by Redrup, are still in existence. In 1913 Redrup moved to Leeds where he designed and built engines for Vickers for their aircraft. In 1919 he designed

68-452: A path that oscillates along the shaft's length as observed from a non-rotating point of view away from the shaft. The greater the disk's angle to the shaft, the more pronounced is this apparent linear motion. The apparent linear motion can be turned into an actual linear motion by means of a follower that does not turn with the swashplate but presses against one of the disk's two surfaces near its circumference. The device has many similarities to

85-463: A series of pistons aligned parallel with a shaft through a swashplate to pump a fluid. A common example of a swashplate application in a fluid pump is the compressor of a present-day automobile air conditioning system. By varying the angle of the swashplate, the pistons' stroke (and, therefore, the compressor's cooling capacity) can be dynamically adjusted. A helicopter swashplate is a pair of plates, one rotating and one fixed, that are centered on

102-554: A simply-equipped home workshop, and often said that he made most of his engines with little more than "a knife and fork". He was the inventor of "Wobble-Plate" axial engines , which powered a motor launch and a Crossley Motors car in the 1920s. A variant of the engine also flew in a Simmonds Spartan aircraft in 1929, and was exhibited at the Olympia Air Show in July of that year. He also designed radial engines for Avro in

119-474: A smaller 250 cc version of his radial engine mounted horizontally in a Royal Enfield motorcycle frame, and was assembled by him and his son. Swashplate engine A swashplate consists of a disk attached to a shaft. If the disk were aligned perpendicular to the shaft, then rotating the shaft would merely turn the disk with no reciprocating (or swashplate ) effect. But instead the disk is mounted at an oblique angle, which causes its edge to appear to describe

153-503: A three-cylinder 309 cc radial engine for motorcycles in partnership with Leeds motorcycle builder Monty Beaumont, and also sold the engines for industrial use. The "Redrup Radial", as the motorcycle was known, was built in the UK from 1919 to 1922, though actual numbers built are unclear and probably less than 150. The magazine The Motor Cycle tested the engine and found little wrong with it. Redrup carried out most of his development work in

170-665: The Avro Lancaster and other aircraft, including the hydraulic drive for the Vickers Type 464 bouncing bomb which was used in Operation Chastise in 1943. After the war he designed more motor-cycle engines, including an axial engine, and large 1,000 and 2,000 hp axial aircraft engines. A 3-cylinder Redrup 1948 Radial Motorcycle is preserved in the Sammy Miller Museum. The motorcycle uses

187-596: The Great Western Railway company for a five-year period. After a short round-trip aboard a merchant ship to America, Redrup returned to Barry, entered into a partnership with Alban Richards, the son of a Barry blacksmith , and set up the Barry Motor Company . He started his married life in the aforementioned parental-gifted house and by 1925 Charles and Jessie Redrup had a family of eight. The Barry Engine first appeared in 1904 when it

204-402: The cam . Swashplates can be used in an axial engine in place of a crankshaft to translate the motion of a piston into rotary motion. Such engines are the only variation of the cam engine to have any success. Internal combustion engines and Stirling engines have been built using this mechanism. Duke Engines has been working on such a platform since 1993. The axial piston pump drives

221-550: The 1920s. As a result of his engine shown at the Olympia Air Show, he was engaged by the Bristol Tramways and Carriage Company to design an engine for them, and moved to Bristol where he designed the Bristol Axial Engine. It was a 7-litre, 9 cylinder, wobble-plate type engine. It was originally conceived as a power unit for buses, possibly because its compact format would allow it to be installed beneath

238-446: The main rotor shaft. The rotating plate is linked to the rotor head, and the fixed plate is linked to the operator controls. Displacement of the alignment of the fixed plate is transferred to the rotating plate, where it becomes reciprocal motion of the rotor blade linkages. This type of differential pitch control, known as cyclic pitch, allows the helicopter rotor to provide selective lift in any direction. The swashplate can also transfer

255-483: The vehicle's floor. The engine had a single rotary valve to control induction and exhaust. Several variants were used in Bristol buses during the late 1930s. The engine went through several versions from RR1 to RR4, which had a power output of 145 hp at 2900 rpm. Development was halted in 1936 following a change of management at the Bristol company. During World War II he worked on top-secret armament projects for

272-530: Was a British aeronautical engineer and inventor, who designed several innovative axial engines . Redrup was born in Newport , Wales in 1878, to wealthy parents. His father moved to Barry, Vale of Glamorgan shortly afterwards. The Redrup family had 10 children, all of whom were able to receive a good private education, due to the family money. Charles Redrup was interested in engineering from an early age and his father paid for him to take an apprenticeship with

289-612: Was exhibited at the Stanley Exhibition in London 's Burners Hall. Designed by Redrup, the engine was a two-cylinder supercharged rotary engine . The engine was incorporated in the unusual "Barry" motorcycle, which retained the pedals of a conventional cycle, with the engine rotating on the forward frame tube between the driver's knees. It was exhibited in London in 1905, attracting a large amount of interest and being reviewed by
