Aircraft Diesel Engine
The aircraft diesel engine or aero diesel is a diesel-powered aircraft engine. They were used in airships and tried in aircraft in the late 1920s and 1930s, but were never widely adopted until recently. Their main advantages are their excellent specific fuel consumption, the reduced flammability and somewhat higher density of their fuel, but these have been outweighed by a combination of inherent disadvantages compared to gasoline-fueled or turboprop engines. The ever-rising cost of avgas and doubts about its future availability have spurred a resurgence in aircraft diesel engine production in the early 2010s. Using diesel engines in aircraft is additionally advantageous from the standpoint of environmental protection as well as the protection of human health, since the tetraethyllead antiknock ingredient of avgas has long been known to be highly toxic as well as polluting. Development Early diesel aircraft A number of manufacturers built diesel aero engines in the 1920s and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stinson Detroiter
The Stinson Detroiter was a six-seat cabin airliner for passengers or freight designed and built by the Stinson Aircraft Company, Stinson Aircraft Syndicate, later the ''Stinson Aircraft Corporation''. Two distinct designs used the Detroiter name, a biplane and a monoplane. Development The first design from the Detroit-based Stinson Aircraft Syndicate was the Stinson SB-1 Detroiter, a four-seat cabin biplane with novel features such as cabin heating, individual wheel brakes and electric starter for the nose-mounted 220 hp (164 kW) Wright J-5 Whirlwind engine. It made its first flight on Jan 25th, 1926. The Harley Davidson brakes were demonstrated on a snowy maiden flight requiring wheel chains to be added to prevent skidding. This aircraft was soon developed into the six-seat Stinson SM-1D Detroiter, a braced high-wing monoplane version which ultimately made quite a number of significant long-range flights. The aircraft was soon a success and it enabled Stinson to get ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strategic Bomber
A strategic bomber is a medium- to long-range Penetrator (aircraft), penetration bomber aircraft designed to drop large amounts of air-to-ground weaponry onto a distant target for the purposes of debilitating the enemy's capacity to wage war. Unlike tactical bombing, tactical bombers, Penetrator (aircraft), penetrators, fighter-bombers, and attack aircraft, which are used in air interdiction operations to attack enemy combatants and military equipment, strategic bombers are designed to fly into enemy territory to destroy strategic targets (e.g., infrastructure, logistics, Military base, military installations, factories, etc.). In addition to strategic bombing, strategic bombers can be used for tactical bombing, tactical missions. There are currently only three countries that operate strategic bombers: the United States, Russia and China. The modern strategic bomber role appeared after Strategic bombing during World War II, strategic bombing was widely employed, and Atomic bombing ...

LZ 129 Hindenburg
LZ 129 ''Hindenburg'' (; Aircraft registration, Registration: D-LZ 129) was a German commercial passenger-carrying rigid airship, the lead ship of Hindenburg class airship, its class, the longest class of flying machine and the largest airship by envelope volume. It was designed and built by the Zeppelin Company (Luftschiffbau Zeppelin, ''Luftschiffbau Zeppelin GmbH'') on the shores of Lake Constance in Friedrichshafen, Germany, and was operated by the German Zeppelin Airline Company (''Deutsche Zeppelin-Reederei''). It was named after Field Marshal Paul von Hindenburg, who was President of Germany (1919–1945), President of Germany from 1925 until his death in 1934. The airship first flew from March 1936 as a #Die_Deutschlandfahrt, Nazi propaganda vessel until it Hindenburg disaster, burst into flames 14 months later on May 6, 1937, while attempting to land at Naval Air Engineering Station Lakehurst, Lakehurst Naval Air Station in Manchester Township, New Jersey, at the end ...

Zeppelin
A Zeppelin is a type of rigid airship named after the German inventor Ferdinand von Zeppelin () who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874Eckener 1938, pp. 155–157. and developed in detail in 1893.Dooley 2004, p. A.187. They were patented in German Empire, Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word ''zeppelin'' came to be commonly used to refer to all forms of rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins German strategic bombing during World War I, as bombers and aerial reconnaissance in World War I, as scouts.

Daimler-Benz DB 602
The Daimler-Benz DB 602, originally known as Daimler-Benz LOF.6, was a German diesel cycle aero engine designed and built in the early 1930s. It was a liquid-cooled upright V16, and powered the two ''Hindenburg''-class airships. It has roughly the same displacement and weight of the Beardmore Tornado, which was used in the ill-fated R101 R101 was one of a pair of British rigid airships completed in 1929 as part of the Imperial Airship Scheme, a British government programme to develop civil airships capable of service on long-distance routes within the British Empire. It was d ..., but has almost twice the power of the Tornado, showing Daimler-Benz's superior knowledge regarding diesel engine construction. Also, these engines, under designation MB 502, powered four Schnellboot-type attack craft of 1933 series S10...13 (three engines on each). The engine was modified into V20 MB 501 of 2000 hp that had a variety of applications. Applications DB 602 * LZ 129 ''Hin ...

Napier Culverin
The Napier Culverin was a licensed built version of the Junkers Jumo 204 six-cylinder vertically opposed liquid-cooled diesel aircraft engine built by D. Napier & Son. The name is derived from the French word, culverin, for an early cannon or musket.Lumsden 2003, p.170. First flown in 1938, the engine went into limited production, with testing carried out on a Blackburn Iris V biplane flying-boat aircraft and Fairey IIIF biplane.Lumsden 2003, p.170. Design The six cylinders were arranged vertically. Two crankshafts were located at the top and bottom of the engine and coupled together by gears. The inlet and exhaust ports were controlled by the pistons, as in a petrol-fuelled two-stroke engine.

Napier & Son
D. Napier & Son Limited was a British engineering company best known for its luxury motor cars in the Edwardian era and for its aero engines throughout the early to mid-20th century. Napier was founded as a precision engineering company in 1808 and for nearly a century produced machinery for the financial, print, and munitions industries. In the early 20th century it moved for a time into internal combustion engines and road vehicles before turning to aero engines. Its powerful Napier Lion, Lion dominated the UK market in the 1920s and the Second World War era Napier Sabre, Sabre produced in its later versions. Many world speed records on land and water, as well as the Hawker Typhoon and Hawker Tempest, Tempest fighter planes, were powered by Napier engines. During the Second World War the company was taken over by English Electric, and engine manufacture eventually ceased. Today, Napier Turbochargers is a subsidiary of the American company Wabtec.

Blohm & Voss Ha 139
The Blohm & Voss Ha 139 was a four-engined, all-metal, inverted gull wing floatplane, designed and built by the Nazi Germany, German aircraft manufacturer Blohm & Voss (aircraft), Blohm & Voss. At the time of the first aircraft's completion, it was one of the largest float-equipped seaplanes to have been built. Development of the Ha 139 started in 1935 to fulfil a specification issued by the German flag carrier ''Deutsche Luft Hansa''. Built to serve on the airline's long distance routes, it was equipped with four hydraulically-actuated landing Flap (aeronautics), flaps, was powered by four Junkers Jumo 205C diesel engines, and was suitable for Assisted take-off#Catapults (CATO), catapult-assisted takeoffs. The Ha 139A was promptly followed by the Ha 139B, a variant that possessed greater size and weight. Development of the aircraft led to a land-based version, the Blohm & Voss BV 142 and a proposed reconnaissance/bomber variant of the Ha 139 for the ''Luftwaffe'' was never reali ...

Opposed-piston Engine
An opposed-piston engine is a piston engine in which each cylinder (engine), cylinder has a piston at both ends, and no cylinder head. Petrol and diesel opposed-piston engines have been used mostly in large applications such as ships, military tanks, and factories. Current manufacturers of opposed-piston engines include Cummins, Achates Power, and Fairbanks-Morse, Fairbanks-Morse Defense (FMDefense). Design Compared to contemporary Two-stroke engine, two-stroke engines, which use a conventional design of one piston per cylinder, the advantages of the opposed-piston engine are: * Eliminating the cylinder head and valve-train, which reduces weight, complexity, cost, heat loss, and friction loss of the engine. * Creating a Two-stroke engine#Uniflow-scavenged, uniflow-scavenged movement of gas through the combustion chamber, which avoided the drawbacks originally associated with the Two-stroke engine#Cross-flow-scavenged, crossflow-scavenged designs of early piston-engines. * A ...

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, power cycle with two strokes of the piston, one up and one down, in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle. During the stroke from bottom dead center to top dead center, the end of the exhaust/intake (or Scavenging (automotive), scavenging) is completed along with the compression of the mixture. The second stroke encompasses the combustion of the mixture, the expansion of the burnt mixture and, near bottom dead center, the beginning of the scavenging flows. Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringe ...
