Two prototypes were built in October 1941. It was ordered for production, under the designation KC-20 (or KTs-20) for designers' initials and the number of troopes carried. 68 were built in 1942-1943. They were produced in a wood industry works in Lopatino village near Kazan. The KC-20 was the biggest, but least numerous of Soviet transport ...
The SGS 2-33, indicating Schweizer Glider, Sailplane, 2 Seats, Model 33, was designed by Ernest Schweizer. The aircraft was a derivative of the 2-22, which in turn was based on the SGU 1-7 single place glider of 1937. The 2-33 retained the 2-22 and 1-7's metal wing, single spar and single strut arrangement. [1] [2] [5]
A Chase XG-20 glider, which was later converted to the XC-123A prototype. The XC-123 prototype. The C-123 Provider was designed originally as an assault glider aircraft for the United States Air Force (USAF) by Chase Aircraft as the XCG-20 (Chase designation MS-8 Avitruc) [2] Two powered variants of the XCG-20 were developed during the early 1950s, as the XC-123 and XC-123A.
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. [2] [3] The prototype 2-22 was flown in March, 1946.
[3] The 2-32 was designed to be the highest performance two-place glider available, when it first flew in 1962. The 2-32 has been used as a tourist glider, trainer, cross-country and high-altitude sailplane and has set many US and world records. A total of 87 aircraft were completed. [1] [3] [4] [5]
If a greater number of 1-34s had been built, Schweizer indicated that it would have become another one-design class, similar to the 1-26. [3] The 1-34 type certificate is currently held by K & L Soaring of Cayuta, New York. K & L Soaring now provides all parts and support for the Schweizer line of sailplanes. [4] [5]
[1] [2] The 1-19 was a 1944 development of the pre-war SGU 1-7 and bears a strong resemblance to the earlier craft. It was designed for single place training and soaring flights. [1] [3] The 1-20 was an improved version of the 1-19 with a wingspan of 43 feet (13 m) replacing the 36-foot (11 m) wing on the 1-19. [1] [3]
The wings are removable using the same design as the 1-26. The engine uses a cowling with exposed cylinders like a J-3 Cub for simplicity and cooling efficiency. Wing mounted spoilers were retained from the 1-26, allowing steep low-speed descents at about a 5:1 glide ratio. Three sets of wings were tested including a set from the model 2-31.
