The Schweizer SGS 1-24, also referred to as the Schweizer-Burr SGS 1-24, is a United States single-seat, mid-wing, Open Class competition glider built by Howard Burr and Schweizer Aircraft of Elmira, New York.
Design and development
The early 1950s were the heyday of the SGS 1-23 design. From the time of its introduction in 1948 the production sailplane had dominated soaring contests in the USA.
Schweizer Aircraft employee Howie Burr conceived of creating an improved version of the 1-23 by using the existing fuselage and building a set of 17.10:1 aspect ratio wings for the aircraft. The 55-foot (17 m) span wings gave the aircraft a 30:1 glide ratio and a low 2.0-foot-per-second (0.61 m/s) minimum sink speed. Those performance figures are identical to the 1-23D
Burr finished the aircraft in his spare time, flying it first in early 1953. The 1-24 was ready for competition flying in time for the 1953 US Nationals, which were held at Harris Hill, New York.
The design incorporated some innovative concepts in addition to the high aspect ratio wing. It had a shuttle weight that could be moved by cable through the length of the tail that allowed the glider to be trimmed anywhere between 50 mph (80 km/h) and 80 mph (129 km/h).
Burr entered the 1-24 in the 1953 US Nationals and the Snowbird meet held at Harris Hill over Thanksgiving, 1955. In the Snowbird meet, Burr flew the 1-24 to second place against a field of 25 sailplanes.
The 1-24 was loaned to Paul A. Schweizer to compete in the 1957 US Nationals, which were held in Elmira, New York. Burr was unable to fly the 1-24 in that contest himself, as he was contest director. Paul Schweizer did not complete the competition as his father died during the contest and he withdrew.
In 1969, the 1-24 was sold to Carl Waters and moved to California. Burr later re-purchased the aircraft from Waters and carried out a complete restoration of it, including the original name "Brigadoon".
