Note: for military transports, it's probably easier to use the corresponding civil template and add an armament section from the base template if necessary. Aircraft name goes here Image caption
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 Discus was the first production sailplane to have a distinctive swept-back leading edge. This is now common in contemporary sailplanes. Studies had long shown that the ideal wing for minimizing induced drag should be an elliptic planform. To keep production costs down, a triple-trapezoidal approximation of this shape was adopted for the Discus.
By default, the template will round the result of any measurement unit conversions. The default precision is such that the converted (output) value has approximately the same number of significant figures as the unconverted (input) value. To override the significant figures, use |measurement sigfig= where measurement is the measurement being ...
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]
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.
It is a Standard Class glider with a 15-metre span, and laminar-flow airfoil section designed by Professor Franz Wortmann. The all-moving tailplane, a feature of many designs of that period due to its theoretically higher efficiency, caused less than desirable high-speed stability characteristics, and so modifications were made to the early design.
A version with an 18-metre span, with the option of smaller wing tips to fly as a Standard Class glider, was launched in 2004 and designated Discus-2c. [1] When fitted with a small sustaining engine (turbo) it is designated Discus-2cT. [2]
