Hiduminium
The Hiduminium alloys or R.R. alloys are a series of high-strength, high-temperature aluminium alloys, developed for aircraft use by Rolls-Royce ("RR") before World War II. They were manufactured and later developed by High Duty Alloys Ltd. The name ''Hi''-''Du''-Minium is derived from that of ''Hi''gh ''Du''ty Alu''minium'' Alloys. The first of these Hiduminium alloys was termed '' 'R.R.50' ''. This alloy was first developed for motor-racing pistons, and was only later adopted for aircraft engine use. It was a development of the earlier Y alloy, the first of the nickel-containing light aluminium alloys. These alloys are one of the three main groups of high-strength aluminium alloys, the nickel-aluminium alloys having the advantage of retaining strength at high temperatures, making them particularly useful for pistons. Early adoption The alloys were in limited use for aircraft by 1929, being used in the Rolls-Royce R engine that was successful in the Schneider Trophy ...

Y Alloy
Y alloy is a nickel-containing aluminium alloy. It was developed by the British National Physical Laboratory during World War I, in an attempt to find an aluminium alloy that would retain its strength at high temperatures. Duralumin, an aluminium alloy containing 4% copper was already known at this time. Its strength, and its previously unknown age hardening behaviour had made it a popular choice for zeppelins. Aircraft of the period were largely constructed of wood, but there was a need for an aluminium alloy suitable for making engines, particularly pistons, that would have the strength of duralumin but could retain this when in service at high temperatures for long periods. The National Physical Laboratory began a series of experiments to study new aluminium alloys. Experimental series "Y" was successful, and gave its name to the new alloy. Like duralumin, this was a 4% copper alloy, but with the addition of 2% nickel and 1.5% magnesium. This addition of nickel was an innovation ...

Armstrong-Siddeley Special Six Engine, In Hiduminium Alloy (Autocar Handbook, 13th Ed, 1935)
Armstrong Siddeley was a British engineering group that operated during the first half of the 20th century. It was formed in 1919 and is best known for the production of luxury vehicles and aircraft engines. The company was created following the purchase by Armstrong Whitworth of Siddeley-Deasy, a manufacturer of fine motor cars that were marketed to the top echelon of society. After the merge of companies, this focus on quality continued throughout in the production of cars, aircraft engines, gearboxes for tanks and buses, rocket and torpedo motors, and the development of railcars. Company mergers and takeovers with Hawker Aviation and Bristol Aero Engines saw the continuation of the car production which ceased in August 1960. The company was absorbed into the Rolls-Royce conglomerate which was interested in the aircraft and aircraft engine business. Eventually, the remaining spares and all motor car interests were sold to the Armstrong Siddeley Owners Club Ltd, which now ow ...

Piston
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts downwards through the connecting rod and onto the crankshaft. The connecting rod is att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Siddeley, 1st Baron Kenilworth
John Davenport Siddeley, 1st Baron Kenilworth (5 August 1866 – 3 November 1953), was a pioneer of the motor industry in the United Kingdom, manufacturing aero engines and airframes as well as motor vehicles. Career The eldest son of William Siddeley and his wife born Elizabeth Davenport, J D Siddeley was born in Longsight, Manchester in 1866 and first worked for his father as an apprentice hosier but took night classes in draughting. In 1892, the young bicycle racer and designer was hired as a draughtsman by the Humber Cycle Company. The then managing director of Dunlop picked him out at Humber and hired Siddeley as Dunlop's Belfast sales manager. In 1900 as managing director of Dunlop's Midlands subsidiary Clipper Tyre Company he gained prominence in the motor industry by driving a 6 hp Daimler car through England's Thousand Miles Trial with marked success.Lord Kenilworth.

Rolls-Royce R
The Rolls-Royce R is a British aero engine that was designed and built specifically for air racing purposes by Rolls-Royce Limited. Nineteen R engines were assembled in a limited production run between 1929 and 1931. Developed from the Rolls-Royce Buzzard, it was a 37-litre (2,240 cu in) capacity, supercharged V-12 capable of producing just under 2,800 horsepower (2,090 kW), and weighed 1,640 pounds (770 kg). Intensive factory testing revealed mechanical failures which were remedied by redesigning the components, greatly improving reliability. The R was used with great success in the Schneider Trophy seaplane competitions held in England in 1929 and 1931. Shortly after the 1931 competition, an R engine using a special fuel blend powered the winning Supermarine S.6B aircraft to a new airspeed record of over 400 miles per hour (640 km/h). Continuing through the 1930s, both new and used R engines were used to achieve various land and water sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ABC Hornet
The ABC Hornet was an 80 hp (90 kW) four-cylinder aero engine designed in the late 1920s by the noted British engineer Granville Bradshaw for use in light aircraft. The Hornet was effectively a double Scorpion and was built by ABC Motors, first running in 1929.Lumsden 2003, p. 54. In 1931 the engine was re-designed, including the adoption of the new Hiduminium alloys for the crankcase, exhaust manifolds and pistons.

Aluminium Alloy
An aluminium alloy (or aluminum alloy; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', Arnold, 1995 Alloys c ...

Wallace Charles Devereux
Wallace Charles Devereux CBE (9 March 1893 – 21 June 1952) was a British businessman and engineer, known for his work in producing light alloys for the aircraft industry. Education He was born in Aston, now part of Birmingham, in 1893, then educated at Erdington High School. He then studied for three years at Birmingham School of Art, the subjects including machine design and metallurgy. First World War During the First World War, Devereux was appointed to the post of tool room superintendent of National Aircraft Factory No. 1. His study of airframe and engine design during this period, and in the years immediately following the war, convinced him of the possibilities of forged light alloys. Aircraft airframes, as well as engines, were now in a transitional phase and moving to the increased use of light alloys for construction, rather than wood or iron. Between the wars Following the end of the war he became works manager at Peter Hooker's where he began to realise t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
