The Moswey III is a Swiss mid-wing, single-seat, gull winged glider that was designed by Georg Mueller and produced by Moswey Segelflugzeug-Werke.[1][2]


Design and development

The Moswey series of gliders was developed prior to the Second World War in 1938. The third model was the first one to achieve full production status.[1]

The aircraft is built from wood. The fuselage is a monocoque design, while the wings and tail surfaces are a wooden frame covered in doped aircraft fabric covering. The fuselage is of a hexagonal section forward and a diamond section aft. The fuselage is built upon a main keel beam that also contains the control runs. The 14.0 m (45.9 ft) span wing is a gulled design, employing a Goettingen 535 airfoil, with air brakes for glidepath control. The structure is stressed for aerobatics at +/-12g.[1][3]

The Moswey III was constructed by building the fuselage around a large tube, which was then removed after construction.[1]

The cockpit is noted for its small dimensions, with the wing roots providing the pilot's shoulder and elbow room.[1]

The Moswey III was not type certified and at least 30 were built.[1][2]

Operational history

One Moswey III was imported into the United States and remains on the Federal Aviation Administration aircraft registry in the Experimental - Racing/Exhibition category.[1][2]
