The Development of the Secondary Wing Structure for a Rigid Wing Hang Glider

摘要

The design, construction and testing of a secondary wing structure using foam and glass fiber sandwich construction are described. Materials and construction techniques used were those readily available to the amateur. The wing section, an FX 72-MS-150B, was modified to simplify construction. Load tests were conducted on the iron on plastic film covering material. Static loading tests and an aerodynamic loading test in a wind tunnel were carried out, the latter on a 1.52 m span, section of the full scale wing. The structure proves to be more than adequately strong, although its weight would be only 4.14 kg.
