Schweizer Aircraft originally proposed the idea of a simple, inexpensive, one-design class sailplane at the 1945 Motorless Flight Conference. [2] This concept was revived in 1954. At that time the Schweizer SGS 1-23 was the only sailplane in production in the United States and demand for it had dropped off, due to its high price. At the same ...
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]
The company identified that there was demand from private owners and especially clubs and commercial operations for a simple, rugged single seat glider with greater performance than the 1-26. [3] In service the 1-34 has proven to be a popular club aircraft and ideal for the completion of badge flights. If a greater number of 1-34s had been ...
The DG-101 and DG-101G had improvements such as a single-piece front-hinged canopy, improved crash resistant cockpit and a conventional tailplane (with fixed horizontal stabilizer and articulated elevator). There was also a club version of this sailplane with fixed landing gear. All models featured top-surface-only air brakes.
Schweizer Aircraft started construction of the 1-35 prototype in late 1972 and it first flew in April 1973. The company carried out side-by-side comparisons with fiberglass sailplanes as part of 50 hours of flight evaluations before making the decision to proceed with manufacturing the design on 10 May 1973.
The Mosquito had a new design of one-piece canopy rather than the two-piece canopy used on the Hornet. This profile and its sister profile FX 67-K-150 are among the most prolific in the history of gliding, as they were employed also in the Nimbus-2 , Mini-Nimbus , DG-200 and DG-400 , PIK-20 , Kestrel , Mosquito, Vega , Jantar and LAK-12 among ...
The self-launching PIK-20E is similar to the D model, but has a retractable Rotax 501 that takes 15 turns of a manual crank in the cockpit to deploy or retract. The fuselage is slightly different, with a slight sweep-back of the wings and the tailplane is larger. [ 4 ]
The designers desired to demonstrate that high performance and pleasant flight characteristics could coexist in a standard class sailplane built with the then still-unexplored GRP technology. The performance improvements came from the wing having a high aspect ratio , the double tapered wing; and the new FX 66-S-196 laminar-flow airfoil profile ...
