Mathematical model of the pitching seaplane on the mode drift

Abstract

The mathematical model of the dynamics of pitching seaplane under conditions of regular and irregular excitement on the mode drift is developed. The model is based on the ways that is used in solving the problem of pumping ships, but it considers the significant differences in the geometry between ships and seaplanes. Only vertical vibrations and oscillations of the angle of pitch and roll is considered. For verification of matmodel calculations of the dynamics of rolling and pitching motion of the model of a seaplane in conditions of the regular waves were made and the results of calculation and experiment in the testing pool was compared. Some results of the behavior of the seaplane under conditions of irregular excitement, allowing to predict the maximum permissible level of excitement, are obtained.
