Wpływ sztywności i tłumienia w układzie sterowania sterem wysokości na stateczność podłużną samolotu i oscylacje steru

In the paper, the titled problem, including the analysis of elevator mass balance, is presented. The equations of motion of an aircraft with oscillating elevator are derived by application of Boltzmann-Hamel's equations for holonomic systems. The solution is obtained by the method of eigen-values and eigenvectors of the state matrix. The numerical calculations performed for the light aircraft are compared with results for the same aircraft with blocked elevator.
