Junkers Jumo 204
The Jumo 204 was an opposed-piston, inline, liquid-cooled 6-cylinder aircraft Diesel engine produced by the German manufacturer Junkers. It entered service in 1932. Later engines in the series, the Jumo 205, Jumo 206, Jumo 207 and Jumo 208, differed in stroke, bore, and supercharging arrangements. Design and development Development of the Junkers diesel engines started in the 1920s with the Junkers Fo3 and Junkers Fo4/Junkers SL1. The Fo4 was re-designated Junkers 4, which in turn was re-designated Junkers Jumo 204 by the Reichsluftfahrtministerium (RLM), where the first number indicates the manufacturer; 2 – Junkers Motoren. These engines used a two-stroke cycle with six cylinders and twelve pistons, in an opposed piston configuration with two crankshafts, one at the bottom of the cylinder block and the other at the top, geared together. The pistons moved towards each other during the operating cycle. There were two cam-operated injection pumps per cylinder, each feeding two ...

Junkers G
Junkers Flugzeug- und Motorenwerke AG (JFM, earlier JCO or JKO in World War I, English: Junkers Aircraft and Motor Works) more commonly Junkers , was a major German aircraft and aircraft engine manufacturer. It was founded in Dessau, Germany, in 1895 by Hugo Junkers, initially manufacturing boilers and radiators. During World War I and following the war, the company became famous for its pioneering all-metal aircraft. During World War II the company produced the German air force's planes, as well as piston and jet aircraft engines, albeit in the absence of its founder who had been removed by the Nazis in 1934. History Early inter-war period In the immediate post-war era, Junkers used their J8 layout as the basis for the F-13, first flown on 25 June 1919 and certified airworthy in July of the same year. This four passenger monoplane was the world's first all-metal airliner. Of note, in addition to significant European sales, some twenty-five of these airplanes were delive ...

Aircraft Diesel Engines
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-stroke Diesel Engines
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 ...

Blohm & Voss BV 138
The Blohm & Voss BV 138 ''Seedrache'' (Sea Dragon) was a trimotor flying boat designed and built by the Nazi Germany, German aircraft manufacturer Blohm & Voss (aircraft), Blohm & Voss. It served as the ''Luftwaffe''s primary seaborne long-range maritime patrol and Aerial reconnaissance, naval reconnaissance aircraft operated by the ''Luftwaffe'' during the Second World War. The BV 138 was a pre-war design by Dr Richard Vogt (aircraft designer), Richard Vogt, originally developed under the company name of Hamburger Flugzeugbau, and thus it was initially designated ''Ha 138'' instead. It had an uncommon appearance due to its combination of unusual design features, such as its twin boom tail unit, short Hull (watercraft), hull, and trimotor engine configuration. In reference to the side-view shape of its fuselage, the aircraft was often referred to via the nickname ''Der Fliegende Holzschuh'' ("Flying clog (shoe), Clog").Nowarra 1997, original German title of the Schiffer book.

Mitsubishi Ki-20
The Mitsubishi Ki-20 is a Japanese bomber variant of the Junkers G.38 airliner. Mitsubishi manufactured six aircraft under license from Junkers. These aircraft, designated Army Type 92 Heavy Bomber, served through the 1930s. During World War II, the Ki-20 served in a variety of transport and support roles. Design and development In the late-1920s, as Junkers developed the Junkers G.38, Mitsubishi representatives in Germany expressed an interest in a military version of this civilian transport. At the time, the G.38 was the largest landplane in the world. Junkers completed a design study for a military bomber/transport, based on the G.38, designated the K.51. This design was not accepted by the Reichsluftfahrtministerium. The K.51 design study was of interest to Japan. A licensing and manufacturing agreement was reached and in 1932, the first two Ki-20s were completed by Mitsubishi, utilizing Junkers-made parts. A prototype was successfully flown in Japan by a German test pilot i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junkers Ju 86
The Junkers Ju 86 is a monoplane bomber and civilian airliner designed and produced by the Germany, German aircraft manufacturer Junkers. It was designed during the mid-1930s in response to a specification for a modern twin-engined aircraft suitable for use as both a high-speed airliner and a bomber. Junkers responded with a low-winged twin-engined all-metal monoplane; unusually, it was intended to be powered by Junkers Jumo 205 diesel engines instead of petrol engines for greater fuel efficiency. It also had a smooth metal skin instead of the company's traditional Corrugated galvanised iron, corrugated exterior. On bomber-configured aircraft, bombs were carried vertically in four fuselage cells behind the cockpit; these bomb cells were replaced by seating for up to ten passengers on the civil airliner version of the Ju 86. On 4 November 1934, the first prototype, powered by Siemens-Halske Sh 22, Siemens SAM 22 radial engines, made its maiden flight; on 4 April 1935, th ...

Junkers Ju 52/1mdo
The Junkers Ju 52/3m (nicknamed ''Tante Ju'' ("Aunt Ju") and ''Iron Annie'') is a transport aircraft that was designed and manufactured by German aviation company Junkers. First introduced during 1930 as a civilian airliner, it was adapted into a military transport aircraft by Germany's Nazi regime, who exercised power over the company for its war efforts, over the objections of the company's founder Hugo Junkers. Development of the Ju 52 commenced in the late 1920s, headed by German aeronautical engineer Ernst Zindel. The aircraft's design incorporated a corrugated duralumin metal skin as a strengthening measure, which was a material design pioneered by Junkers and used on many of their aircraft, including the popular Junkers F 13 1920s, the record-setting Junkers W 33, and Junkers W34. The corrugation was both a strength and a weakness; it provided increased structural strength but also increased aerodynamic drag. But more importantly it allowed the practical use of aluminum ...

Deutsche Luft Hansa
''Deutsche Luft Hansa A.G.'' (from 1933 styled as ''Deutsche Lufthansa'' and also known as ''Luft Hansa'', ''Lufthansa'', or DLH) was a German airline. It served as flag carrier of the country during the later years of the Weimar Republic and throughout Nazi Germany, when it had close links to the Nazi Party. Although Deutsche Luft Hansa was the forerunner of modern German airline Lufthansa (founded in 1953) and both airlines share the same logo, there is no legal connection between the two. However, the new Lufthansa took over staff from the old airline and claims DLH's legacy. For this reason it is controversial in the historical reappraisal to what extent the modern Lufthansa should confess to crimes committed by the old airline. History 1920s Deutsche Luft Hansa was founded on 6 January 1926 in Berlin. The name of the company means "German Hansa of the Air". The Hansa or Hanseatic League dominated maritime trade in the Baltic Sea area for hundreds of years, and is well reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
