The history of the development of the expense of building a traditional class of models of gliders is replete with numerous examples of advances in the field of aerodynamics and design and technology. In the late 60-ies the emergence of a dynamic hook has led to a “boom” design creativity in the development of reliable and efficient mechanization of models of gliders. Great contribution to this was made by Soviet athletes being recognized legislators “mod” in aeromodelling sport in the world. Estonian master, world champion 1989, Andres LLP, Kharkov scientist Victor Isaenko, Leningrad, Yuri Yablokov, Kiev engineer Victor Stamov are in fact the founders of new directions the last decade. But despite the achievements of the Ukrainian school (V. Chop), Russian (V. Etenko), Estonian (A. Lelp), Moscow school gliding is particularly. We can talk about it how about giving the sports world a unusual design, receiving subsequently wide distribution. First of all, this high performance culture, advanced technology and unusual materials distribution in the models of G. Orlov, and S. Makarova (1980-1985 gg.), and more recently a number of young talented athletes — Mikhail Kochkarev, A. Litura etc.
Latest new sports season, struck many athletes at all competitions, was a rebalance of the model gliders of the Muscovites in the derailment of a rail in a nearly vertical mode.
A sharp rebalancing of bearing areas with a standard degradation (the difference between the angles of the wing and stabilizer on the plan is usually equal to 3-3,5° C) to a significant negative (-5°) and then return to its original position is widely used by almost all timeritem. And was first used in 1974, a nine-time champion of the USSR, the triple champion of Europe and world champion Eugene Verbitsky Kharkov. This gave the opportunity to more fully use the kinetic energy of the model and to reduce the height loss during the transition from vertical take-off mode for planning. Previously used the outputs of the rudder and the stall model with a deep sideways slide could result in loss of approximately half of the possible suction height. This kind of rebalancing on the models of gliders tried to introduce the City eagles in the 1979 — 1980, but never brought it. A year ago at the training camp of the USSR team before the trip to the world Cup in Argentina Odessa Victor Chop with all the titles: champion of the USSR, Europe and the world, were a little bit shocked the leading glider pilots in the country with ultra-reliability starts with “Tierney” double rebalancing. All is well, and, it would seem, then seems to think there is nothing. But Muscovites went on an incredible and normal standards is absolutely the wrong direction: they increase the negative angle of degradation (lowering of the rear edge by 20 mm!) to -15°! that’s just tripled the deflection angles. What is the result?
