The Schweizer SGU 2-22 is a United States two-seat, high-wing, strut-braced, training glider built by Schweizer Aircraft of Elmira, New York.
The 2-22 was designed to replace the two-place training gliders surplussed at the end of World War II . Production was started in 1946 and it was produced until 1967, when it was superseded by an improved version, the SGS 2-33. From the 1940s until the 1960s it was the most numerous two-place training glider in the USA.
The end of World War Two resulted in a large number of military training gliders being sold as surplus. These included Frankfort TG-1s, Schweizer TG-2s and Schweizer TG-3s. Most of the surplus gliders sold were not ideal trainers for ab initio civilian student flying, as they had high wing loadings and faster stall speeds. This made them suitable for aerotow, but not for winch or auto-tow launches. Furthermore, many of these surplus two-place gliders had poor visibility from the rear seat where the instructor sat. Due to restrictions on the use of aluminum in training aircraft, many surplus gliders had wooden wings, making them unsuitable to be kept outdoors on tie-downs.
Schweizer Aircraft decided to design a two-place trainer that would address these deficiencies and provide a trainer that was easy to fly and would be easy for students to progress quickly on. The new two-place was intended to be a complement to the single-place training glider then in production, the SGU 1-19.
The SGU 2-22, indicating Schweizer Glider, Utility, 2 Seats, Model 22, was designed by Ernest Schweizer. The aircraft was based on the SGU 1-7 single place glider of 1937. It used the 1-7's metal wing, single spar and single strut arrangement. The prototype 2-22 was flown in March, 1946. To gain publicity for the new design company test pilot Frank Hurtt and company engineer Dick Powell used the prototype to set a new two-place duration record of 10 hours 9 minutes on April 10, 1946. The 2-22 was produced in seven variants and remained in production for 21 years. Production was only curtailed when the Schweizer SGS 2-33 was put into production as a replacement. The 2-33 was essentially a refined 2-22, incorporating a longer semi-tapered wing.
