Helicopter aerodynamics is the study of the behavior of air and the forces that act on a helicopter as it moves through the air. It is a critical aspect of helicopter design, performance, and operation. The unique characteristics of helicopters, such as their rotor blades, hubs, and control systems, require a specialized understanding of aerodynamics. You will often see this book searched for

When the engine fails, the pilot immediately lowers the collective pitch, allowing the helicopter to descend. As it descends, the upward flow of air through the rotor disk drives the rotor like a windmill. Leishman breaks the autorotating rotor blade down into three distinct regions:
