Drgania samolotu w ustalonym ruchu spiralnym

Jerzy Maryniak, Jędrzej Trajer

In the paper a method of analysis of airplane small wibrations about the equilibrium position in a steady spiral motion is presented. The motions disturbances near equilibrium point are diseussed according to Lapunow method. The analysis is based on a full set of motion differential equations, linearised in accordance with the theory of small disturbances. A comparative analysis of results for selected parameters is presented.
