Entwicklung und Erprobung von Leichtflugzeugen (EEL) (English: Development and Testing of Light Aircraft) is a German aircraft design firm based in Putzbrunn. The company was founded in 1976 by Heiner Neumann and Dieter Reich. It specializes in the design of gliders and motor gliders, provided in the form of plans for amateur construction. [1] [2]
Both Neumann and Reich studied aeronautics in the early 1960s while at Technische Universität Berlin. Reich designed the two aircraft marketed by EEL. [3]
The EEL ULF 1, a foot-launched microlift glider that weighs 55 kg (121 lb) empty, first flew in November 1977. The EEL ULF 2 is a single-seat motorglider that first flew in October 1993. As a result of his design work on the ULF 2 Reich received the Oskar Ursinus Vereinigung (OUV) Hans-Becker-Prize in June 1997. [1] [2] [4]

The Game of Life, also known as Conway's Game of Life or simply Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970. It is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an initial configuration and observing how it evolves. It is Turing complete and can simulate a universal constructor or any other Turing machine.
The Bachem Ba 349 Natter is a World War II German point-defence rocket-powered interceptor, which was to be used in a very similar way to a manned surface-to-air missile. After a vertical take-off, which eliminated the need for airfields, most of the flight to the Allied bombers was to be controlled by an autopilot. The primary role of the relatively untrained pilot was to aim the aircraft at its target bomber and fire its armament of rockets. The pilot and the fuselage containing the rocket engine would then land using separate parachutes, while the nose section was disposable.
The history of aviation spans over two millennia, from the earliest innovations like kites and daring attempts at tower jumping to supersonic and hypersonic flight in powered, heavier-than-air jet aircraft. Kite flying in China, dating back several hundred years BC, is considered the earliest example of man-made flight. Leonardo da Vinci's 15th-century dream of flight found expression in several rational designs, though hindered by the limitations of contemporary science.
Percy Sinclair Pilcher was a British inventor and pioneer aviator who was his country's foremost experimenter in unpowered flight near the end of the nineteenth century.
Fritz Adam Hermann von Opel, known as Fritz Adam Hermann Opel until his father was ennobled in 1917, was the only son of Wilhelm von Opel and a grandson of Adam Opel, founder of the Opel company. He is remembered mostly for his Opel RAK demonstrations of the world's first manned rocket-powered ground and air vehicles that earned him the nickname "Rocket Fritz" and which were also highly effective as publicity stunts for his family's automotive business.
This is a list of aviation-related events from 1902:
Gordon Gollob was an Austrian fighter pilot during World War II. A fighter ace, he was credited with 150 enemy aircraft shot down in over 340 combat missions. Gollob claimed the majority of his victories over the Eastern Front, and six over the Western Front.
An eel is a fish in the order of Anguilliformes.
An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries. Most have electric motors driving propellers or turbines.
Theodor Weissenberger was a German Luftwaffe military aviator during World War II and a fighter ace credited with 208 enemy aircraft shot down in 375 combat missions. The majority of his victories were claimed near the Arctic Ocean in the northern sector of the Eastern Front, but he also claimed 33 victories over the Western Front. He claimed eight of these victories over the Western Allies while flying the Messerschmitt Me 262 jet fighter.
Anton "Toni" Hackl was a German Luftwaffe military aviator during World War II, a fighter ace credited with 192 enemy aircraft shot down in over 1,000 combat missions. The majority of his victories were claimed over the Eastern Front, with 87 claims over the Western Front. Of his 87 victories over the Western Allies, at least 32 were four-engined bombers, a further 24 victories were unconfirmed.
Günther Radusch was a World War II German Luftwaffe pilot and wing commander. As a fighter ace, he claimed 65 enemy aircraft shot down in over 140 combat missions. He claimed one victory in the Spanish Civil War. During World War II, he was credited with 64 aerial victories in Defense of the Reich all of which claimed at night and includes the destruction of 57 four-engined bombers.
Willi Reschke was a Luftwaffe ace and recipient of the Knight's Cross of the Iron Cross during World War II, credited with 27 aerial victories in 70 missions. In 1999, Reschke recounted his wartime experiences in print, published in English in 2005 as "Jagdgeschwader 301/302 'Wilde Sau': In Defense Of The Reich with the Bf 109, Fw 190 and Ta 152;" including writing about the late-war period he spent flying the exotic Focke-Wulf Ta 152 high-altitude fighter-interceptor designed by Kurt Tank.
The EEL ULF 1 is a West German high-wing, single-seat, foot-launched, microlift glider that was designed by Dieter Reich. When it was available it was provided in the form of plans by Entwicklung und Erprobung von Leichtflugzeugen (EEL) for amateur construction. By the end of 2019 the company website had been take down and it is likely that the company has gone out of business.
The EEL ULF-2 is a German low-wing, conventional landing gear, single-seat motor glider that was designed by Dieter Reich and is provided in the form of plans by Entwicklung und Erprobung von Leichtflugzeugen for amateur construction.
A glider called a Large Biplane was designed and built in 1895 as an advanced stage of the Lilienthal Normalsegelapparat – a monoplane glider invented by Otto Lilienthal. The Normalsegelapparat was patented in Germany in 1893, and later in 1895 in the United States and was the first production aircraft in history. Like its preceding model, the Large Biplane is a hang glider which is controlled through weight-shift by the pilot, as hang gliders are to this day.
