Schweizer / SGS 1-29

Glider Reg. Number: -

1948

Design & Development

The Schweizer SGS 1-29 is an American single-seat, mid-wing, experimental laminar flow airfoil glider built by Schweizer Aircraft of Elmira, New York.

The 1-29 is a development of the Schweizer SGS 1-23 that utilizes a 1-23 fuselage and a newly constructed set of 49.2 foot (15.0 m) span wings.

The aircraft was constructed to study the feasibility of producing improved boundary layer laminar flow on a metal-winged sailplane. Only one SGS 1-29 was produced and the project was not pursued further.
