MODERN WING TECHNOLOGY FOR GENERAL AVIATION AIRCRAFT

TRAGFLUEGEL NEUER TECHNOLOGIE FUER FLUGZEUGE DER ALLGEMEINEN LIFTFAHRT

This report contains the results of investigations of aerodynamic and structural design and trade-off concerning the application of modern wing technology (TNT) for aircraft. The aerodynamic design of the test-wing shows the clear superiority of the TNT-wing section compared to conventional NACA-wing sections, mainly with regard to maximum lift and L/D at high lift coefficients. Wind tunnel investigations, made with the complete experimental model aircraft, partly exceeded the theoretical expectations. The class of general aviation aircrafts ranges from light single-engined aircrafts of less than 2000 lb gross weight to twin-engined commercial aircrafts of up to 12,500 lb gross weight. Because of this large take-off-weight range no generally applicable wing structure exists, which is cost-effective for all general aviation aircrafts. Additionally, the most effective wing structure depends on the different production know-how and the available production facilities of the component companies.
