A performance prediction technique is presented for flush inlet waterjet systems installed on planing craft. The equations were derived based on empirical data and physical reasoning. This technique may be used to find an optimum waterjet configuration for a given planing craft, based on desired propulsive efficiency, weight, power, craft speed, waterjet size or any combination of these parameters. The useful domain of this technique is bound by the data base used in the derivation, which is a collection of commercially available waterjets. Radically new waterjet configurations would require an update of the equations based on empirical data. Experimental and analytical work is recommended for the predictions of flush inlet head recovery and of pump cavitation characteristics. New data would improve the accuracy of the current mathematical model. (DePo)
