Comment:
The 15-meter Ventus (not to be confused with the later completely redesigned Ventus 2) has all- carbon fiber wings. The strength of this material permitted use of a very thin airfoil developed by F.X. Wortmann, Dieter Althaus and Ventus designer Klaus Holighaus. The stiffness of carbon fiber prevents wing twist at high speeds such as often occurs with fiberglass. The Ventus first flew in 1980 and was offered with an A model for shorter pilots, and a slightly wider and longer B model for pilots up to 196 cm/ 6 feet/ 5 inches in height. The Ventus has trailing-edge combination flaps and dive brakes, and aileron control mixers which reduce aileron deflection when extreme positve or negative flap is selected. The B model had optional 16.6 m. tip extensions, while the C model offered 15 m. winglets tip extensions increasing the span to 16.6 or 17.6 m., and a 5 kg. /11 lb. Fin ballast tank. Dick Johnson tested a modified Ventus A with 16.5 m. tip extensions to give a demonstrated best L/D of 50 at 78 kph/ 42 kt/ 48 mph and a minimum sink rate of 0.43 m/s/ 1.42 fps/ 0.84 kt. The sustainer Ventus bT had 16.6 m. wings and a retractable 15 kW/ 20 bhp Oehler Solo turbo engine. The cT had 17.6 m. wings and a Solo engine uprated to 22 kW/ 30 bhp. A Ventus won the 15 m. class at the 1983 World Championships at Hobbs, NM, and others took 10 of the first 15 places. R.L. Robertson of Great Britain, along with others, won the world triangle distance record of 1,363 km./ 846.9 miles in 1986 in a Ventus A. Specifications are for the Ventus A.
