Abstract:

Methods are given for obtaining the Hydroskimmer response for the three lateral degrees of freedom and both rudder and variable nozzle control systems. Solutions are obtained in terms of Laplace transforms for any control input and in real time for a step control input. The solutions for the step input depend on functions of the craft stability and control derivatives and these functions are presented graphically in terms of the fundamental craft parameters. The parameters considered are the rudder chord, rudder area, rudder longitudinal distance from the c.g., craft beam, jet thickness and jet exit height. Skeg and water depression effects are briefly discussed. Author
