A Homebuilt Two-seater Powered Sailplane: Some Design Considerations

Alex Strojnik

Abstract


An attempt is described to combine a reasonable soaring performance (L/D 35, sink rate 120 ft/min) with good cross-country power-on performance, comparable to that of the Cessna 150/152. It is found that witha 15-meter, very high aspect ratio wing, a low-weight structure can be built and that less than 30 bhp are required for more than 100 mph in level fight or more than 500 ft/min climb in the two-seater configuration.
