| Abstract |
We consider a holonomic non-conservative mechanical system with two degrees of freedom
that simulates the motion of a vane on the elastic bushing of the helicopter’s main or rudder screw in
the thrust plane. The system experiences the action of potential, nonconservative positional forces
and linear dissipative forces, which describe the effect of internal friction during deformation of the
vane and the effect of the external environment. A multiparameter family of stationary solutions of the
model is described, and an investigation of Lyapunov’s stability of a trivial solution in the presence of
small linear friction forces is carried out. Ziegler’s areas were plotted for different values of the problem parameters. |
