描述.This SpringerBrief focuses on modeling and power evaluation of high-speed craft. The various power prediction methods, a principal design objective for high-speed craft of displacement, semi-displacement, and planing type, are addressed. At the core of the power prediction methods are mathematical models for resistance and propulsion efficiency. The models are based on the experimental data of various high-speed hull and propeller series. The regression analysis and artificial neural network (ANN) methods are used as an extraction tool for this kind of mathematical models. A variety of mathematical models of this type are discussed in the book..Once these mathematical models have been developed and validated, they can be readily programmed into software tools, thereby enabling the parametric analyses required for the optimization of a high-speed craft design. This book provides the foundational reference for these software tools, and their use in the design of high-speed craft. High-speed craft are very different from conventional ships. Current professional literature leaves a gap in the documentation of best design practices for high-speed craft. .This book is aimed at naval arc

Power Prediction, often planing regimes, as discussed in Sect. .. Specifically, with increasing speed HSC change both the displacement and trim, which is not the case with conventional (displacement) ships. Therefore, in order to model the HSC’s operating conditions and power requirement, equations of equilibrium must be formed.

Mathematical Modeling,e present author used two methods—statistical data modeling tools—to extract (i.e. develop) the mathematical models for prediction of resistance and propulsive coefficients: a) Regression analysis, and b) Artificial Neural Networks (ANN).

Resistance and Dynamic Trim Predictions,MMs for high-speed round bilge hull forms were re-evaluated recently, see Sahoo et al. (.). In the following text 18 MMs are discussed and 10 are recommended as they have not yet been superseded. These MMs are presented in Tables . and .. Some of them form the basis of current computerized resistance prediction software packages.

Resistance and Dynamic Trim Predictions,ressed earlier, for instance by van Oossanen (.), Almeter (.), and others, but these are now outdated and merit an update. Some resistance prediction MMs for high-speed round bilge hull forms were re-evaluated recently, see Sahoo et al. (.). In the following text 18 MMs are discussed and 10 are reco

,Propeller’s Open-Water Efficiency Prediction,ds are used. Two main differences should be emphasized: 1. Dependent variables that should be modeled simultaneously are thrust coefficient and torque coefficient. By definition, these coefficients are interrelated (linked) through the expression for the open water efficiency. 2. While the dependent

Additional Resistance Components and Propulsive Coefficients,ents consist of those that: 1. Increase the resistance from bare hull total resistance in deep and calm water to in-service total resistance (i.e. from R. to R.*), and 2. Account for the hull-propeller interaction (i.e. propulsive coefficients).
