Ship Propeller

This paper describes state-of-the-art manufacture of ship propeller blades with numerically controlled(NC) machining. A brief explanation of the rationale for NC machining is provided, followed by a discussion of the operating experience of a blade machining center over the past six years. Some of the unique considerations involved in the NC programming and machining processes are described along with some of the most common production problems. The factors leading to the company's decision to expand the blade machining center are discussed along with a description of the design and procurement of the new equipment and facilities. Tolerances achieved by NC machining and hand finishing are compared.

A brief summary is given of efforts in the field of naval architecture on the problem of determining the vibratory forces and moments produced by a ship propeller, and an account of the principal contributions made by aeronautical researchers on the problem of computing the fluctuating pressure field near a propeller. This pressure is derived from a lifting-line representation and the expressions are then interpreted in terms of the fields of two doublet distributions. It is shown that this result can be verified by specializing the expressions for the sound-pressure field of a propeller. Some characteristics of the pressure field are discussed briefly. Detailed evaluations and comparison with experiment will be presented in a subsequent paper.
