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.
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 glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). [ 1 ] [ 2 ] This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude.
HpH 304 is a family of sailplanes ranging from a single-seat composite 15 metre Class to a two-place 20 metre Open Class manufactured by the Czech company HpH Ltd.The sailplane was derived from a glider made by Glasflügel between 1980 and 1982 that was put back in production by HpH and who have modified it substantially and developed new models since.
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.
Grob G103 Twin II landing. Clear view of the new three-wheel undercarriage configuration. The G103 Twin II (a.k.a. the Twin Astir II) is the successor of the original G103 Twin Astir with a nose wheel and a fixed six-inch main gear fitted behind the center of gravity - The main wheel is equipped with a hydraulic brake.
The DFS was involved in producing training sailplanes for the Hitler Youth and Luftwaffe, as well as conducting research into advanced technologies such as flying wings and rocket propulsion. Notable DFS-produced aircraft include the DFS 230 transport glider (1600+ produced), the German counterpart to the British Airspeed Horsa glider, and the ...
