Helicopter aerodynamics

Helicopter aerodynamics involve how helicopterrotor blades generate lift, allowing it to take off, hover, and move in various directions. As blades spin, they behave like airplane wings, creating a pressure difference: higher pressure below the blades and lower pressure above, which lifts the helicopter upward. By adjusting blade angles (pitch) and rotor speed, pilots control movement and stability. The main forces involved include lift, which supports the helicopter's weight; thrust, to move forward or sideways; and drag, which opposes movement. Understanding these principles enables precise control of helicopter flight and maneuverability.
