Nonlinear regular and chaotic dynamics of a helicopter

Dżygadło Z., Kowaleczko G.

Journal of Technical Physics

2001

Vol. 42, no 2

241-268

A helicopter is a rotorcraft, which can be subjected, during its motion, to various types of vibrations. This paper presents selected results of analysis of these vibrations. It is carried out on the basis of the complete set of nonlinear differential equations describing the helicopter fuselage motion and all the blades motions. For the helicopter performing a steady-state flight, the control law for static autopilot is formulated on the basis of the method of motions separation. In the case of a ground resonance the forces and moments produced by a landing gear are taken into consideration. The flutter phenomenon is also simulated. Some results of numerical analysis are presented, which show that some oscillations are regular and others have rather a chaotic character.
