EAGES 01 - Introduction to WIG Technology - Edwin van Opstal

INTRODUCTION

Edwin van Opstal is a trained engineer from Delft University.
In 1995 he launched the WIG Page, soon to become the main reference for ground effect information, papers and data. Edwin then launched S.E. Technology which was involved in the design of numerous projects, then launched Edenka, a small product development consultancy company based in The Netherlands.
Edwin gives here a great introduction to ground effect technology and all the aspects to be looked at when starting a project.

ABSTRACT

WIG is short for Wing-In-Ground effect. Ground effect is an aerodynamic phenomenon that is used by WIG boats to achieve high speed over water with minimum fuel consumption. The current paper will first answer the question what a WIG boat is and have a look at its history followed by an introduction to the aerodynamics of WIG boats. Then some attention is given to the different concepts that have been developed over the years, aimed at solving the particular problems of WIG boats : taking-off and  longitudinal stability. Finally some operational issues including classification will be discussed and commercial viability of WIG boats is assessed.
