The stability of the equilibrium of a wing in an unsteady flow (English)
0 references
The author considers the motion of a heavy rigid wing with a fixed point under the action of nonstationary flow. It is assumed that the wing form is close to a thin plate, and the wing is fastened using a nonlinear viscoelastic material. The motion of wing is described by a system of nonlinear ordinary integro-differential equations. Using the series similar to those in the first Lyapunov method, the author analyzes the stability of wing equilibrium for rotational motion of wing.
