Airplane Design and Construction (Classic Reprint)

AIRPLANE DESIGN AND CONSTRUCTION PART I STRUCTURE OF THE AIRPLANE CHAPTER I THE WINGS While for birds, and in general for all animals of the air, wings serve to insure both sustentation and propulsion, those of the airplane are used solely to provide the means of sustaining the machine in the air. The phenomenon of sustentation is easily explained. A body moving through the air produces, because of its motion, a disturbance of the atmosphere which is more or less pronounced and complex in character. In the final analysis, this disturbance is reduced to the formation of zones of positive and negative pressures. The resultant of these pressures may then be classified into its three components: 1. Vertical or sustaining force, called Lift, 2. Horizontal component parallel and opposite the line of flight, called Drag, and 3. Horizontal component perpendicular to the line of flight, called Lateral Drift. The vertical component may be positive or negative. An example of the negati
