The Swiss SGS 2-32 is an American glider manufactured by the Schweizer Aircraft Corporation . It is currently the only three-seater glider in the world, but not registered in Germany.
history
The SGS 2-32 was designed as a performance glider and set several height and distance records. Like the successful L-13 Blanik , also in metal construction, the SGS 2-32 comes from the short transition phase from wood or composite construction to plastic construction.
The ability to carry two passengers made the SGS 2-32 very popular for commercial guest flights. The load on the rear seats is limited to 68 kg each. With a limited take-off weight, the SGS 2-32 is suitable for aerobatics .
Further developments
The SGS 2-32 is the basis for some further developments. The Lockheed YO-3 A, a particularly quiet reconnaissance aircraft, and the LTV L450F are known above all . In addition, several other companies developed other motorized variants.
construction
The SGS 2-32 is a cantilevered middle decker with single-spar, metal-clad, all-metal wings. The ailerons are covered with fabric. Air brakes are installed above and below the wings to limit the speed . The fuselage is an all-metal shell construction with an elevator designed as a pendulum rudder and fabric-covered control surfaces. The unicycle undercarriage with an additional runner is not retractable.
