559) glided for a while and survived the landing, but he was executed shortly after. 550–559) had members of the rival Yuan and Tuoba clans attached to kites and launched from the top of the Tower of the Golden Phoenix in the capital, Ye, China, as test pilots Yuan Huangtou (d. As a form of execution, the notoriously cruel Emperor Wenxuan of Northern Qi (r. The Chinese Daoist writer Ge Hong (284–364 AD) wrote that kite vehicles with frames made of wood from the jujube tree had ox-leather straps "fastened to returning blades" that could allow the device to soar high into the air. The sleek high performance jets, sailplanes and hang gliders of today have a heritage that dates back to man’s first attempts at flight. Gottlob Espenlaub's first hang gliding competition at Wasserkuppe, Germany, 1921. The wing's simplicity of design and ease of construction, in combination with its slow flight characteristics, did not go unnoticed by hang glider enthusiasts Rogallo's flexible wing airfoil was soon adapted to the purpose of recreational flight, launching a hang glider Renaissance. In 1957 the American space agency NASA began testing various formats of a new wing called the Rogallo wing with the intent of possibly implementing the design as a recovery system for the Gemini space capsules. Further hang glider research was undertaken during the 1920s in Europe, Australia and the U.S.A, where designers tested several wing concepts and the 'pendulum weight-shift control system'. The type of aircraft employed by Lilienthal is now referred to as a hang glider. The first recorded controlled flights were by German engineer Otto Lilienthal, whose research, published in 1889, strongly influenced later designers.
OverviewĮarly hang glider designs did not reliably achieve safe flight, their builders lacking a comprehensive understanding of the underlying principles of flight.
The pilot is ensconced in a harness depending from the airframe, and exercises control by shifting body weight in opposition to a control frame. Typically, hang gliders are composed of an aluminium or composite framed fabric wing. Hang gliding is an air sport employing foot-launchable aircraft known as a hang gliders.
