EN457: Hydrofoil & Propeller Design

Catalog Description

EN457: Hydrofoil & Propeller Design (3-0-3)

This course provides an introduction to hydrofoil and marine propeller design.  Students consider lifting-line and lifting-surface theories, as applied to marine hydrodynamics and naval applications.  Computer-aided design work and tow-tank experimentation supplement recitations.

Textbook

  • Principles of Naval Architecture: Resistance, Propulsion, and Vibration (Lewis, 1988)
  • Marine Rudders and Control Surfaces (Molland & Trunock, 2007)
  • Marine Hydrodynamics (Newman, 1977)
  • Hydrodynamics of Ship Propellers (Breslin & Andersen, 1994)
  • Various Handouts & Selected Technical Papers

Goals

  1. Understand applications of computer-aided engineering tools within the field of modern naval architecture.
  2. Understand basic lifting-line and lifting-surface theories, as applied to hydrofoil and marine propeller design.
  3. Understand tow-tank experimentation processes for hydrofoil and marine propeller design.
  4. Develop a greater understanding of fundamental hydrodynamics concepts.
  5. Develop the ability to generate basic three-dimensional models/simulations.
  6. Develop the ability to compare/understand empirical, experimental, and numerical hydrofoil and propeller design outputs.

Prerequisites

  • EN353, Resistance and Propulsion, OR
  • Approval of NAOE Department Chair
