An Experimental Evaluation of Three Methods for Increasing the Leading Edge Thickness of Supercavitating Propellers
Author: Richard A. CUMMING

Pages : 55
Book Description
An experimental investigation of three methods of increasing the leading-edge thickness of supercavitating propeller sections was conducted. The purpose of the investigation was to determine which method could be used that would result in the least impairment of the hydrodynamic performance for a given increase of the leading-edge thickness. The three methods were: (1) arbitrary thickening of the section beyond the bounds of the theoretical cavity; (2) use of a greater angle of attack to increase the thickness of the theoretical cavity and, hence, the allowable section thickness; and (3) addition of a parabolic thickness to both the face and back of the section. Five supercavitating propeller models incorporating these three methods of increasing the section thickness were tested in a water tunnel, for a range of various cavitation numbers and advance coefficients. The results indicate that parabolic thickening of the cavity is superior to the arbitrary thickening of the section beyond the theoretical cavity boundary. Use of an increased angle of attack leads to a greater loss of performance than do the other two methods, but it has excellent resistance to face cavitation and, therefore, is recommended where resistance to face cavitation is of great improtance.

Marine Rudders, Hydrofoils and Control Surfaces
Author: Anthony F. Molland
Publisher: Butterworth-Heinemann
ISBN: 0323853641
Category : Technology & Engineering
Languages : en
Pages : 574
Book Description
The course keeping and manoeuvring requirements for a ship are governed by international maritime law. In assessing and predicting the course keeping and manoeuvring capabilities of the ship, knowledge is required of the rudder forces necessary to keep a course or facilitate a manoeuvre. The second edition of Marine Rudders, Hydrofoils and Control Surfaces includes up-to-date data and rudder design techniques that enable the rudder forces to be estimated, together with any interactions due to the hull and propeller. The new edition describes the design and application of hydrofoils including shape adaptive design, and their applications including hydrofoil craft, yachts, and kite surfing hydrofoils. The professional will also face the need to design control surfaces for motion control, such as roll and pitch, for surface vessels and submersibles, and the book contains the necessary techniques and data to carry out these tasks.This book is for practicing naval architects and marine engineers, small craft designers, yacht designers, hydrodynamicists, undergraduate and postgraduate students of naval architecture, maritime engineering and ship science, and the broader engineering community involved in the development of marine craft that rely on the generation of 'lift' such as control engineers and aerodynamicists. - Describes techniques for analyzing the performance characteristics of rudders, hydrofoils, and control surfaces - Includes extensive design data and worked examples for the analysis of rudder, hydrofoil and control surface performance - Provides a detailed examination of the design of hydrofoils
