Overview. During the past sixty years since their first successful flights, helicopters have matured from unstable, vibrating contraptions that could barely lift the pilot off the ground, into sophisticated machines of extraordinary flying capability. They are able to hover, fly forward, backward and sideward, and perform other desirable maneuvers.
the primary subject of this book. A helicopter can be defined as any flying machine using rotating wings (i.e., rotors) to provide lift, propulsion, and control forces. The rotor pro-duces a lift force equal to the weight of the helicopter and because the generation of this
Igor Ivanovitch Sikorsky (1955) 1.1. Rising Vertically. Aerodynamics is the science of all flight. The role of aerodynamics in the engi-neering analysis and design of rotating-wing vertical lift aircraft, such as the helicopter, is the primary subject of this book.
This chapter is dedicated to present the principles that constitute the fundamentals of helicopter flight physics, starting from the basics of the main rotor aerodynamics and of the component parts related to flight control.
