Dynamika nieautonomicznego przestrzennego ruchu samolotu z odkształcalnymi układami sterowania

Spatial-motion dynamics was studied of an aircraft with deformable controls and movable ponderable control surfaces (ailerons, elevator and rudder) in the case of the external force in the form of pulses acting upon the aircraft in a finite time interval. A full nonlinear set of equations of the aircraft spatial motion was employed along with the equations of motion of the ailerons, the elevator and the rudder on consideration of external actions explicitly time-
dependent. A program was prepared for numerical integration of the equations by the Runge-Kutt-Gill method. The effect was studied of the external force at fixed values of the rigidity and damping coefficients in the control systems upon the spatial motion dynamics of the aircraft. A numerical analysis was also performed of the effect of rigidity and damping in the control systems, as well as a resonance analysis of vibrations of the control surfaces and of their effect upon the aircraft motion dynamics at external forces.
