EN457: Hydrofoil and Propeller Design

Catalog Description

EN457: Hydrofoil and Propeller Design (3-0-3).

The analysis and design of hydrofoils and marine propellers are presented.  Lifting-line and lifting-surface theories are applied to naval devices.  Design and towing-tank work supplements recitations.

Textbook

Class handouts, lecture notes, and selected technical papers.

Goals

  1. Understand basic propeller design concepts and procedures.
  2. Understanding lifting-line and lifting-surface theories.
  3. Understand basic hydrofoil design and associated hydrodynamic principles.
  4. Apply course lectures/principles to the design and/or analysis of a unique propeller and/or hydrofoil shape.
  5. Understand design optimization principles, as applied to propeller and/or hydrofoil design.

Prerequisites

EN353 or Approval of Department Chair
