Akaflieg Darmstadt is one of approximately twenty aviation groups attached to German universities. Akaflieg is an abbreviation for Akademische Fliegergruppe, an academic group of students and faculty from a German University.
The Hannover H.1 Vampyr was a German glider designed by Georg Madelung for the 1921 Rhön gliding competition, which was held at the Wasserkuppe from 8 August to 25 August 1921. The Vampyr is believed to be the first heavier than air aircraft to use stressed skin. Several historical societies have argued that the aircraft is the precursor of all modern sailplanes.
The Akaflieg Darmstadt D-7 Margarete, often shortened to Darmstadt D-7 Margarete, was one of the earliest two seat monoplane gliders, designed and built by German university students in 1923.
The Akaflieg Darmstadt D-9 Konsul, often shortened to Darmstadt D-9 Konsul, was a high performance, single seat, cantilever monoplane sailplane, designed and built by a German University student group in 1923 for hill soaring.
The Akaflieg Darmstadt D-17 Darmstadt, also called the Darmstadt D-17 and Darmstadt I, was a high performance, single seat, cantilever monoplane sailplane, designed and built by a German University student design group in 1927. It was followed in 1928 by the Akaflieg Darmstadt D-19 Darmstadt 2, a similar aircraft with a new profile, longer span wing.
The Akaflieg Darmstadt D-28 Windspiel was a single-seat, high-performance sailplane designed in Germany in the early 1930s. Intended to exploit a growing understanding of thermal soaring, it was small and manoeuvrable, with a 12 m span; silk-covered for lightness, it weighed less (empty) than its pilots. It held the world straight-line distance record for a time in 1934.
The Akaflieg Darmstadt D-34 sailplanes were a series of experimental single seat sailplanes, designed at the University of Darmstadt in the 1950s and early 1960s to explore the structural and aerodynamic advantages of the then emerging plastics and composite materials.
The CVV1 Pinguino was a single seat, high performance glider designed and built in Italy in the mid-1930s, the first of a series of gliders from the Milan Polytechnic. It did not go into production.
The DFS Rhönsperber, otherwise known as the Schweyer Rhönsperber or Jacobs Rhönsperber was a single seat competition glider designed in Germany by Hans Jacobs and first flown in 1935. For several years it was regarded as the best German sailplane and about one hundred were built.
The DFS Reiher was a single seat competition glider designed in Germany by Hans Jacobs and first flown in 1937. The type won the last two German Rhön gliding championships before the start of World War II. Six were factory produced.
The Schleicher Rhönbussard, otherwise known as the DFS Rhönbussard was intended as an intermediate glider trainer which could also fly competitively. It was designed by Hans Jacobs in Germany in the early 1930s. More than 200 were built.
The Schleicher Rhönadler, DFS Rhönadler or Jacobs Rhönadler is a high performance, single seat competition sailplane built in Germany in the 1930s. More than 65 were built.
The RRG Fafnir, named after the legendary dragon, was a single seat German high performance glider designed by Alexander Lippisch. It won the Rhön competition in 1931 and made several outstanding flights as well as setting a fashion for gull wings.
The RRG Professor was a very early soaring glider and the first to use a variometer for finding thermals. It was designed by Alexander Lippisch in Germany, first flying in 1928. The Professor was widely built by both flying clubs and factories.
Lore and a copy, Musterle, were high performance sailplanes designed at Darmstadt by Paul Laubenthal. Lore was flown successfully by the well known glider pilot Wolf Hirth at the 1929 Rhön (Wasserkuppe) glider competition. Musterle was used by Hirth used to demonstrate the possibilities of "blue sky" thermalling for the first time.
The Laubenthal Württemberg, sometimes known after its constructors as the Akaflieg Darmstadt Württemberg, was a single seat glider designed by Paul Laubenthal and built at the University of Darmstadt for Wolf Hirth, who won four prizes in it at an international competition in France in 1928. A second machine was built in 1929 by the Klemm Leichtflugzeugbau GmbH.
The Der Dessauer, later Der alte Dessauer, was a German single-seat glider built in the early 1920s. It took part in all the Rhön gliding contests on the Wasserkuppe between 1923 and 1928, flew in the Alps, and made a long-duration flight along the German sea shore.
The BSV Luftikus was a German competition glider, designed for economy of construction and first flown in 1929. From 1929 to 1931 it took part in the annual national gliding contests held on the Wasserkuppe, often known as the Rhön contests.
The F.V.D. Doris or Dresden Doris, later known as the Akaflieg Dresden D-B2 Doris, was a monoplane glider built in Germany in 1922. It was unusual in having wings which could independently adjust their angles of attack, a feature intended to increase the energy acquired from gusts of wind.
The Akaflieg Hannover H.2 Greif was a 1922 development of the successful Vampyr glider. Though it flew in three successive Rhön (Wasserkuppe) contests, it failed to match the achievements of its predecessor.
