ABOUT LARGE U SHAPE WING OF GLIDER AIRPLANE MODEL

The U large wing is a new proposed shape of the glider airplane model wing. Its stability is compared to V wing. U large wing I/II has increased stability as the tilting angle increases, less than for V wing I/ II. Its strong instability is at beta = 90 degrees, when the wing is in vertical position. Its stability range is larger than for V wing. The V wing has the stability range limited by a, being 90 degrees - alpha., where a is the angle between wings and horizontal line, in normal flight. beta is the tilting angle for the wing. It can be trigonometric or anti trigonometric rotation, seen from the tale.
