Design and development

edit

The AS 33 is based upon the ASG 29, with a totally new wing with an 18 m (59 ft) span and 10 m2 (110 sq ft) area, which optimizes the airflow around the fuselage/wing transition as well as at the wingtips. The AS 33 is a single-seat, mid-wing sailplane of composite construction, with a T-tail.[2] To fly in the FAI 15m class, a second pair of outer wings is available. The separation point for the outer wings is at 5.1m along the span.[5]

The glider has upward extending three-tier air-brakes and independently switchable electrical valves for the water ballast tanks in the inner and outer wings. The main wheel has a disc brake. The main wheel and the tail-wheel are retractable.[5]

Schleicher no longer includes the designer's initial in the glider's designation.[6]
