Stories about the competition Experiment, systematically held in our country attract attention of not only athletes modelers, but readers are far from this sport. So unusual look time, rezinomotornaya and gliders-“wings”, even a cursory view of the magazine of their photographs compel us to pay attention.
However, models of gliders, successfully used in the competition “family crew” — L. Klimov and his son Yuri — surprise even experienced the “experimenters”. The fact that the soaring leader-the”wing” has already swept the unusual shape, and in plan resembles the letter M. Yes, and the front model is unusual — a transverse V-wing set according to the scheme of “the Seagull.” As a result, the soaring leader Klimov are so similar in flight on this bird, what made once deceived even the dog. She ran behind the glider in the hope about to catch sitting down on the field “game”.
But the outward signs of this new model. Is it ever justified from the point of view of aerodynamics, bring any improvement in flight characteristics of soaring leader? In saying this brilliant performance of Klimov at the event.
The wing, as already mentioned, the plan is similar in form the letter M. the Central part with a constant chord and back sweep 5°, console areas with a significant narrowing of the direct sweep of 30° to the front edge. The transverse V is formed by setting the center of the wing at 15° from the front, then after the bend shape angle reduced to 5°.
