Training double-seat glider MAI-227 — the glider for all generations of people.
The idea of creation of a glider of such class has appeared because of absence in the market of simple training gliders, such as BRO-11 and LAK-16, in «Soviet» time extraordinary widely applied in youth glider schools (Yu.P.Sh.).
On the other hand, training on a single glider though was widespread in days of Soviet Union, is recognised now by inefficient and unsafe. Besides, as it is not paradoxical, training on a single glider of the adult person is interfaced to the big problems.
One more difference of MAI-227 from the listed gliders is larger lift-drag ratio (18) that allows it to carry out soaring flight. Such high enough lift-drag ratio is reached, including at the expense of «a clean» wing (in the aerodynamic meaning) from composite materials.
