The design and construction of a wing of modern technology (MWT) for general aviation aircraft is reported as well as testing of this wing on a modified Dornier Skyservant. The results of investigations of aerodynamic and structural design and trade-off concerning the application of the MWT on general aviation aircraft are presented. The aerodynamic design of the test-wing shows the clear superiority of the MWT 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 theoretical expectations. The result of the flight mechanics investigations shows that in comparison with the original Skyservant version, limitations of the flight-envelope will be necessary because of the modified wing, more powerful engines, and the use of the original empennage. The effect of applying MWT to general aviation aircraft was demonstrated on two basic production aircraft. Results showed remarkable improvements of flight and mission performance (take-off run, climb, and range), relatively small improvements in initial costs, and an obvious reduction of direct operational costs.
