ABC Mosquito
The ABC Mosquito was a 120 hp (90 kW) six-cylinder radial aero engine designed by the noted British engineer Granville Bradshaw for use in light aircraft. The single Mosquito engine was built by ABC Motors, first running in 1916. It is thought that the design resulted from a bet between Harry Hawker and Bradshaw, Hawker proposing that Bradshaw could not build and fly a six-cylinder radial engine. The Mosquito used copper-plated steel Gnat cylinders. The engine was not a success.Lumsden 2003, p.51.

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

ABC Motors
ABC Motors Limited ("All British (Engine) Company") of Hersham, Surrey, England was a manufacturer of cars, aircraft, motor scooters, and engines for road and air. Established by Ronald Charteris in Hersham, Surrey in 1912, its chief designer was the young and talented Granville Bradshaw.Lumsden 2003, p. 51. It was absorbed into Vickers in 1951 and the factory finally closed in the 1970s. Some of the premises survive today as part of the Riverdean Estate, Hersham and are occupied by a Lidl supermarket (opened February 2019) Products The ABC radial aero engines of the World War I period were extremely advanced for their time, and were initially thought to be very promising indeed. Unfortunately they were all more or less plagued by problems – and although a number of types for the Royal Air Force were designed around ABC engines (especially the ill-fated ''Dragonfly'') none saw squadron service with the RAF. ABC also made a large number of engines for electrical generators ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granville Bradshaw
Granville Eastwood Bradshaw OBE, AFRAeS (1887–1969) was an English engineer and inventor who designed motorcycle, auto, and aero-engines. History Bradshaw was born in Preston, Lancashire in 1887 as the son of William and Annie Bradshaw. His father was a jeweler and optician. Bradshaw's early work was involved with the early pioneers of flight, which led him to become an expert on stressing. He designed the Star Monoplane including the engine for Star Aircraft when he was 19, which he later flew. He then started to work on aero-engines and was the co-founder of the All-British Engine Company (later ABC Motors then Walton Motors). The ABC radial aero-engines designed and built during the First World War were extremely advanced and the government placed large orders for the Dragonfly. A number of aircraft were designed to use the Dragonfly, but the engines were plagued by problems and failed to live up to the promises. The design was taken over by the Royal Aircraft Establ ...

Harry Hawker
Harry George Hawker, MBE, AFC (22 January 1889 – 12 July 1921) was an Australian aviation pioneer. He was the chief test pilot for Sopwith and was also involved in the design of many of their aircraft. After the First World War, he co-founded Hawker Aircraft, the firm that would later be responsible for a long series of successful military aircraft. He died on 12 July 1921 when the aircraft he was to fly in the Aerial Derby crashed in a park at Burnt Oak, Edgware, not far from Hendon Aerodrome. Early life Hawker was born on 22 January 1889 at Moorabbin, Victoria in Australia, the second son of George Hawker, a blacksmith, and Mary Ann Gilliard Anderson.''The Automobile'' September 2007 Harry Hawker - Automobilist. author Bruce Lindsay He attended Moorabbin Primary School. As an 11-year-old, he worked at the Melbourne garage of Hall & Warden, helping to build engines for five shillings a week, moving on to the Tarrant Motor & Engineering Co, helping make Tarrant cars, whe ...

BAT Bantam
The BAT F.K.23 Bantam was a British single-seat fighter biplane produced by British Aerial Transport Company Limited of London during World War I. Design and development Frederick Koolhoven's first design for the British Aerial Transport Company (BAT) was the F.K.22 single-seat fighter. It was a two-bay biplane of wooden construction. It was planned to have a 120 hp (90 kW) A.B.C Mosquito radial engine but the failure of this engine led to the installation of the 170 hp (127 kW) A.B.C.Wasp I in the first and third aircraft. The second machine was fitted with a 100 hp (75 kW) Gnome Monosoupape rotary engine and was the first to fly at Martlesham Heath in January 1918. The original contract called for six development aircraft but three aircraft were built as the F.K.23 Bantam I, the second prototype then being renamed the Bantam II. The Bantam I was the same wooden structure but was slightly smaller. Two further prototypes of the larger design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succ ...

Octane Rating
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (also called compression-ignition engines) do not compress the fue ...

ABC Motorcycles
ABC motorcycles was a British motorcycle manufacturer established in 1914 by Ronald Charteris in London. Several British motorcycle firms started up with the name "ABC", including Sopwith. The All British Engine Company Ltd. of London was founded in 1912 and later changed to ABC Motors Ltd. With chief engineer Granville Bradshaw, Charteris built a range of engines throughout the First World War. From 1913 ABC produced motorcycle engines. In 1918, ABC made a motorcycle with a 400 cc flat-twin engine mounted with its cylinders across the frame, several years before BMW adapted the design. Bradshaw challenged BMW's use of his patented design in 1926. In 1919 ABC also produced the Scootamota – an early motor scooter. The company stopped producing motorcycles after 1923 because of competition from cheaper manufacturers. Development ABC had always had a close association with the Sopwith aircraft company. They were both at Brooklands and in 1912 a Sopwith with an ABC eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
