| INTRODUCTION TO AERODYNAMICS | ||
One definition of aerodynamics is “the study of the forces exerted on and the flow around bodies moving relative to a gas.” How about a simpler definition – the science of flight. The word comes from two Greek words: airios – concerning the air – and dynamis – meaning powerful. When an object as heavy as a commercial jet can be lifted into the air and controlled on a cross-country journey, powerful forces are at work. The study of aerodynamics helps us to understand how this journey is accomplished. |
