Comment:
The Standard Class Discus A first flew in 1984
using the fuselage and tail unit of the original
Ventus with a new unflapped wing. The wing
planform is noteworthy as being the first
production sailplane to have the now common
distictive shape where the leading edge
sweepback increases towards the tip,
establishing a worldwide trend in wing
planforms. Approach control is by top surface
double panel schempp-hirth airbrakes. There is a
5kg. / 11 lb. Water ballast tank in the fin for
trimming purposes when the main wing mounted
ballast tanks are used. The Discus B
incorporates the longer fuselage (about 23 cm/ 9
in) and roomier cockpit of the Ventus B.
The sustainer engined Discus bT, which first
flew in 1988, has a retractable mast
mounted15kW/ 21 bhp Solo engine with a Oehler
folding prop.
The self-launching Discus bM has a Rotax engine
in the fusealage with a retractable mast mounted
prop.
The Discus won the first three places in the
Standard Class at the 1985 World Championships
at Rieti, Italy, 12 out of the first 15 at the
1987 Worlds at Benalla, Austria, and again the
first three places at the 1989 Worlds at Wiener
Neustadt, Austria. Up to 1995 the Discus won all
first places in the world championships.
The Discus CS is built under license in the
Czech Republic by Orlican. Specifications are
for the Discus A.
The winglets (WL) is an option that was
developed in later stadium for further
improvement of the climb performance. |
