Pulse Jet Engine
300px, Diagram of a pulsejet A pulsejet engine (or pulse jet) is a type of jet engine in which combustion occurs in pulses. A pulsejet engine can be made with few or no moving parts, and is capable of running statically (i.e. it does not need to have air forced into its inlet, typically by forward motion). The best known example may be the Argus As 109-014 used to propel Nazi Germany's V-1 flying bomb. Pulsejet engines are a lightweight form of jet propulsion, but usually have a poor compression ratio, and hence give a low specific impulse. There are two main types of pulsejet engines, both of which use resonant combustion and harness the expanding combustion products to form a pulsating exhaust jet that produces thrust intermittently. The first is known as a valved or traditional pulsejet and it has a set of one-way valves through which the incoming air passes. When the air-fuel is ignited, these valves slam shut, which means that the hot gases can only leave through the engin ...

Paul Schmidt (inventor)
Paul Schmidt (26 March 1898 18 October 1976) was a German aerospace engineer and inventor based in Munich, mainly known for his contribution to the development of the pulsejet. Life Schmidt was born on 26 March 1898 in Hagen, Westphalia. His early work involved efforts to improve the performance and efficiency of aircraft power plants. In 1928 he decided the most promising technology was intermittent thrust generation. With meagre resources, he worked on developing pulse engines. German ministry officials visited him in the early 1930s to make an assessment of his work. He initially started pushing the concept of the pulse engine in 1931. Patent DE523655 contained the first sketch of an impulsive duct. In the mid 1930s, the Luftwaffe was interested in applying Schmidt's work . His development of the Pulse Engine was referred to as the Schmidtrohr (Schmidttube) and he obtained both German and British patents for it. He used the term "pulsating incineration" in reference to the ...

Fieseler
The Gerhard Fieseler Werke (GFW) in Kassel was a German aircraft manufacturer of the 1930s and 1940s. The company is remembered mostly for its military aircraft built for the Luftwaffe during the Second World War. History The firm was founded on April 1, 1930 as Fieseler Flugzeugbau Kassel by World War I flying ace and aerobatic champion Gerhard Fieseler. Fieseler had been a manager for the Raab-Katzenstein, but when this company went bankrupt, Fieseler bought a sailplane factory in Kassel and quickly turned it to building sports planes. At the same time, Fieseler still custom-built sailplanes for some of Germany's most prominent designers and pilots, including Wolf Hirth's "Musterle" and Robert Kronfeld's "Wien" and "Austria" (for many years the largest sailplane ever built). In 1934, the company achieved prominence when Fieseler won the World Aerobatics Championship in an aircraft his company had built, the F2 Tiger. This was followed by the highly successful F5, generall ...

Robert Lusser
Robert Lusser (19 April 1899 – 19 January 1969) was a German engineer, aircraft designer and aviator. He is remembered both for several well-known Messerschmitt and Heinkel designs during World War II, and after the war for his theoretical study of the reliability of complex systems. In the post-war era, Lusser also pioneered the development of modern ski bindings, introducing the first teflon anti-friction pads to improve release. Biography Lusser was born in Ulm. As a pilot, he won the International Light Aircraft Contest in France in 1928. Next he participated in three out of four FAI International Tourist Plane Contests, flying Klemm aircraft, and completed all three taking quite high places (Challenge 1929: 4th, Challenge 1930: 13th, and Challenge 1932: 10th). In August 1930 he was 3rd in the handicapped race ''Giro Aereo d'Italia'' in Italy. Lusser's first jobs were with the Klemm and Heinkel companies, before joining the newly relaunched ''Bayerische Flugzeugwerke'' (Bavar ...

The Askania Company
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Argus Motoren
''Argus Motoren'' was a German manufacturing firm known for their series of small inverted-V engines and the Argus As 014 pulsejet for the V-1 flying bomb. History Started in Berlin in 1906 as a subsidiary of Henri Jeannin's automobile business, ''Argus Motoren'' company spun off entirely in November 1906. Their early products were car and boat engines, but later that year they were contracted to produce engines for the French airship, '' Ville de Paris'', supplying them with a converted boat motor. They turned increasingly to the aviation market, and were widely used by 1910, receiving an order from Sikorsky for one of his large airplanes under construction in Russia. During World War I Argus produced engines for the German army and air corps. After World War I the company manufactured automobile engines and acquired a majority interest in Horch Automobile in 1919. In 1926 they resumed aircraft engine design, producing a series of inverted inline and V engines. Although all ...

V-1 (flying Bomb)
The V-1 flying bomb (german: Vergeltungswaffe 1 "Vengeance Weapon 1") was an early cruise missile. Its official Reich Aviation Ministry () designation was Fi 103. It was also known to the Allies as the buzz bomb or doodlebug and in Germany as (cherry stone) or ( maybug). The V-1 was the first of the (V-weapons) deployed for the terror bombing of London. It was developed at Peenemünde Army Research Center in 1939 by the at the beginning of the Second World War, and during initial development was known by the codename "Cherry Stone". Because of its limited range, the thousands of V-1 missiles launched into England were fired from launch facilities along the French (Pas-de-Calais) and Dutch coasts. The Wehrmacht first launched the V-1s against London on 13 June 1944, one week after (and prompted by) the successful Allied landings in France. At peak, more than one hundred V-1s a day were fired at southeast England, 9,521 in total, decreasing in number as sites were overrun ...

Ribbon Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag or, in a ram-air parachute, aerodynamic lift. A major application is to support people, for recreation or as a safety device for aviators, who can exit from an aircraft at height and descend safely to earth. A parachute is usually made of a light, strong fabric. Early parachutes were made of silk. The most common fabric today is nylon. A parachute's canopy is typically dome-shaped, but some are rectangles, inverted domes, and other shapes. A variety of loads are attached to parachutes, including people, food, equipment, space capsules, and bombs. History Middle Ages In 852, in Córdoba, Spain, the Moorish man Armen Firman attempted unsuccessfully to fly by jumping from a tower while wearing a large cloak. It was recorded that "there was enough air in the folds of his cloak to prevent great injury when he reached the ground." Early Renaissance The earliest evidence f ...

Reich Air Ministry
The Ministry of Aviation (german: Reichsluftfahrtministerium, abbreviated RLM) was a government department during the period of Nazi Germany (1933–45). It is also the original name of the Detlev-Rohwedder-Haus building on the Wilhelmstrasse in central Berlin, Germany, which today houses the German Finance Ministry (german: Bundesministerium der Finanzen). The Ministry was in charge of development and production of all aircraft developed, designed and built in Germany during the existence of the Third Reich, overseeing all matters concerning both military and civilian designs – it handled military aviation matters as its top priority, particularly for the Luftwaffe. As was characteristic of government departments in the Nazi era, the Ministry was personality-driven and formal procedures were often ignored in favour of the whims of the Minister, ''Reichsmarschall'' Hermann Göring. As a result, early successes in aircraft development progressed only slowly and erratically dur ...
