| Abstract: | A linearized analysis of the response of an air cushion vehicle running in waves is described. The analysis uses the linear systems approach where the vehicle is considered to be a “black box”, i.e. the response characteristics are determined experimentally from input-output relationships. The wave forces and moments are expressed in a form that produces the proper limiting behavior for infinite wavelength. Predicted motion response is shown to compare well with experimental data. |
