EFFECT OF ATMOSPHERIC TURBULENCE ON AN AIRPLANE WITH FLEXIBLE WINGS AT DIFFERENT SPEEDS OF FLIGHT

Abstract

A method is described that makes it possible to obtain simply the statistical characteristics of forced vibrations of an elastic airplane wing under the action of atmospheric turbulence. With its help one can take into account vibrations with different degrees of freedom. The increase in the number of degrees of freedom per unit leads to an increase in the order of solvable system of algebraic equations by two units. The standard program it is requires insignificant changes increasing the time for the computation by a small factor. Comparison of the statistical characteristics of vibrations of one and the same model of airplane shows that with sufficiently low frequencies of torsion of a wing close to the critical rates of flutter wing torsion should be considered in computing the joint bending-torsional vibrations of the wing.
