V Engine
A V ENGINE, or VEE ENGINE is a common configuration for an internal combustion engine . The cylinders and pistons are aligned, in two separate planes or 'banks', so that they appear to be in a "V" when viewed along the axis of the crankshaft . The Vee configuration generally reduces the overall engine length, height and weight compared with an equivalent inline configuration. CONTENTS * 1 History * 2 Characteristics * 3 Inverted engines * 4 Specific configurations * 5 See also * 6 References HISTORYThe first V-type engine, a 2-cylinder vee twin, was built in 1889 by Daimler , to a design by Wilhelm Maybach

De Havilland
DE HAVILLAND AIRCRAFT COMPANY LIMITED /dəˈhævᵻlənd/ was a British aviation manufacturer established in late 1920 by Geoffrey de Havilland at Stag Lane Aerodrome Edgware
Edgware
on the outskirts of north London. Operations were later moved to Hatfield in Hertfordshire. Known for its innovation, de Havilland were responsible for a number of important aircraft, including the Moth biplane which revolutionised general aviation in the 1920s, the 1930s Fox Moth , the first commercial transport able to operate without government subsidy, the wooden World War II Mosquito light bomber, and the passenger jet service pioneering Comet . The De Havilland

Blackburn Aircraft Ltd
BLACKBURN AIRCRAFT LIMITED was a British aircraft manufacturer that concentrated mainly on naval and maritime aircraft during the first part of the 20th century. CONTENTS * 1 History * 2 Aircraft * 3 Piston engines * 4 Gas turbine engines (with Turbomeca) * 5 See also * 6 References * 7 External links HISTORYBlackburn Aircraft was founded by Robert Blackburn , who built his first aircraft in Leeds in 1908. The Blackburn Aeroplane & Motor Company was created in 1914, established in a new factory built at Brough , East Riding of Yorkshire in 1916, where Robert's brother Norman Blackburn was later managing director. By acquiring the Cirrus-Hermes company in 1937, Blackburn started producing aircraft engines, the Blackburn Cirrus range. By 1937, pressure to re-arm was growing and the Yorkshire factory was approaching capacity

Sleeve Valve
The SLEEVE VALVE is a type of valve mechanism for piston engines , distinct from the usual poppet valve . Sleeve valve
Sleeve valve
engines saw use in a number of pre- World War II
World War II
luxury cars and in the United States in the Willys-Knight car and light truck. They subsequently fell from use due to advances in poppet-valve technology, including sodium cooling, and the Knight system double sleeve engine's tendency to burn a lot of lubricating oil or to seize due to lack of it. The Scottish Argyll company used its own, much simpler and more efficient, single sleeve system (Burt-McCollum) in its cars, a system which, after extensive development, saw substantial use in British aircraft engines of the 1940s, such as the Napier Sabre and Bristol Hercules and Centaurus , only to be supplanted by the jet engine

X Engine
An X ENGINE is a piston engine comprising twinned V-block engines horizontally opposed to each other. Thus, the cylinders are arranged in four banks, driving a common crankshaft . Viewed head-on, this would appear as an X. X engines were often coupled engines derived from existing powerplants. This configuration is extremely uncommon, primarily due its weight and complexity as compared to a radial engine . It was more compact (per number of cylinders) than a V-engine, however. Shorter crankshafts relative to an inline or V design also appealed to early 20th-century engineers like Henry Ford
Henry Ford
, given the less developed metallurgical technology of the time. Most examples of X engines are from the World War II

era, and were designed for large military aircraft. The majority of these are X-24s based on existing V-12s

Hydraulic
HYDRAULICS (From Greek : Υδραυλική) is a technology and applied science using engineering , chemistry , and other sciences involving the mechanical properties and use of liquids . At a very basic level, hydraulics is the liquid counterpart of pneumatics , which concerns gases . Fluid mechanics
Fluid mechanics
provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow , dam design, fluidics and fluid control circuitry, pumps . The principles of hydraulics are in use naturally in the human body within the heart and the penile erection

Tailhook
A TAILHOOK, ARRESTING HOOK, or ARRESTER HOOK is a device attached to the empennage (rear) of some military fixed-wing aircraft .

Aerial Torpedo
An AERIAL TORPEDO, AIRBORNE TORPEDO or AIR-DROPPED TORPEDO is a naval weapon, a torpedo , that an aircraft—fixed-wing aircraft or helicopter —drops in the water, after which the weapon propels itself to the target. First used in World War I
World War I
, air-dropped torpedoes were used extensively in World War II
World War II
, and remain in limited use. Aerial torpedoes are generally smaller and lighter than submarine- and surface-launched torpedoes. Historically, the term "aerial torpedo" meant flying bombs and pilotless drone aircraft used as weapons, the precursor to modern cruise missiles . Today, the term refers primarily to water-borne torpedoes launched from the air

Yagi Antenna
A YAGI–UDA ANTENNA, commonly known as a YAGI ANTENNA, is a directional antenna consisting of multiple parallel elements in a line, usually half-wave dipoles made of metal rods. Yagi–Uda antennas consist of a single driven element connected to the transmitter or receiver with a transmission line , and additional "parasitic elements " which are not connected to the transmitter or receiver: a so-called reflector and one or more directors. It was invented in 1926 by Shintaro Uda of Tohoku Imperial University , Japan , and (with a lesser role played by his colleague) Hidetsugu Yagi
Hidetsugu Yagi
. The reflector element is slightly longer than the driven dipole, whereas the directors are a little shorter. This design achieves a very substantial increase in the antenna's directionality and gain compared to a simple dipole

Anti-submarine Warfare
ANTI-SUBMARINE WARFARE (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships , aircraft , or other submarines to find, track and deter, damage or destroy enemy submarines. Successful anti-submarine warfare depends on a mix of sensor and weapon technology, training, and experience. Sophisticated sonar equipment for first detecting, then classifying, locating and tracking the target submarine is a key element of ASW. To destroy submarines both the torpedo and mine are used, launched from air, surface and underwater platforms. Other means of destruction have been used in the past but are now obsolete. ASW also involves protecting friendly ships
