A mathematical model is developed for representing the heave, pitch and roll motions of an aircraft carrier at sea. The data is in the form of transfer functions relative to the waves, which are determined for a range of forward speeds and headings considered appropriate to carrier operations during the landing phase. From this information, spectral responses representing the statistical characteristics of motions in certain specific sea states are then developed. The results are presented in a form that can be applied to computer simulation studies for various types of wave disturbances, such as storm conditions, swells, and combinations of such wave systems. The motions of heave and pitch are emphasized, since roll motions are sufficiently small so that they do not significantly influence the aircraft landing operation. Certain limited conclusions as to motion severity and methods for reducing ship motions are outlined, together with recommendations for specific applications and extensions of the theoretical results.
