This book is dedicated to the memory of a distinguished Russian
engineer, Rostislav E. Alexeyev, who was the first in the world to
develop the largest ground effect machine - Ekranoplan. One of
Alexeyev's design concepts with the aerodynamic configuration of a
jlying wing can be seen on the front page. The book presents a
description of a mathematical model of flow past a lifting system,
performing steady and unsteady motions in close proximity to the
underlying solid surface (ground). This case is interesting for
practical purposes because both the aerodynamic and the economic
efficiency of the system near the ground are most pronounced. Use
of the method of matched asymptotic expansions enables closed form
solutions for the aerodynamic characteristics of the
wings-in-ground effect. These can be used for design,
identification, and processing of experimental data in the course
of developing ground effect vehicles. The term extreme ground
effect, widely used through out the book, is associated with very
small relative ground clearances of the order of 10% or less. The
theory of a lifting surface, moving in immediate proximity to the
ground, represents one of the few limiting cases that can be
treated analytically. The author would like to acknowledge that
this work has been influenced by the ideas of Professor Sheila E.
Widnall, who was the first to apply the matched asymptotics
techniques to treat lifting flows with the ground effect. Saint
