Preface

Propulsion, in one form or another, is one of the oldest technologies known to

the human race. This technology has been utilized in various applications from

a simple bicycle to a high-speed bullet train, a catamaran to a submarine, and

a helicopter to a hypersonic missile. The motivation behind propulsion science

and technology has been, from the days of primitive man, to travel, explore,

defend, and sometimes to conquer.
