Lilienthal was not satisfied to restrict his work to the exploration of aerodynamic theory. In 1889 he published his findings in a pathbreaking book called Der Vogelflug als Grundlage der Fliegekunst (Birdflight as the Basis of Aviation). Lilienthal also established definitively the widely held belief that a curved wing section, as opposed to a flat wing surface, was the optimum shape for generating lift. The research produced the best and most complete body of aerodynamic data of the day. In the 1870s he conducted a series of experiments on wing shapes and gathered air pressure data using a whirling arm and in the natural wind. He began research in aeronautics with his brother Gustave in the late 1860s, investigating the mechanics and aerodynamics of bird flight. Lilienthal was trained in the highly regarded German technical education system and earned his living as a professional engineer. The most significant pre-Wright brothers aeronautical experimenter was the German glider pioneer, Otto Lilienthal. They adopted his approach of glider experimentation and used his aerodynamic data as a starting point in their own research. He was a great inspiration to the Wright brothers in particular. Control was achieved by shifting body weight fore-and-aft and from side-to-side.īeyond his technical contributions, he sparked aeronautical advancement from a psychological point of view, as well by unquestionably demonstrating that gliding flight was possible. Like the example in the National Air and Space Museum collection, most were monoplanes with stabilizing tail surfaces mounted at the rear. During this period, Lilienthal made close to 2,000 brief flights in 16 different designs based on aerodynamic research he conducted in the 1870s and 1880s. Between 18, he built and flew a series of highly successful full-size gliders. The most significant pre-Wright brothers aeronautical experimenter was the German glider pioneer Otto Lilienthal.

The HGMA was dissolved in June of 2022 as a result of the decline in activity in hang glider manufacturing. During that time, four hundred and sixty-five documentation packages and addendums were submitted to and accepted by the HGMA. Over its forty-five year history, the HGMA administered a highly evolved set of standards that constitute a current industry consensus definition of what represents airworthiness in a hang glider, and how to test for and document it. Although the first few attempts to develop and administer such standards were not successful, eventually a viable manufacturers association came into being and meaningful hang glider design and testing standards were developed, based initially on the FAA standards for certifying light airplanes. The beginnings of the HGMA date back to December of 1973, when a group of hang glider manufacturers met in Westchester, California to talk about forming an industry association and developing construction standards for hang gliders. Between 19, the Hang Glider Manufacturers Association was an international association of hang glider manufacturers that administered a set of industry consensus airworthiness testing standards for hang gliders.
