- Nota adicional1
- The advancing blade, the blade whose tip is moving in the same direction the helicopter is flying, has a speed equal to its own speed plus the speed of the helicopter. The retreating blade, the blade whose tip is moving in the opposite direction to that which the helicopter is moving, is traveling at a speed equal to its own speed less the speed of the helicopter. Since aerodynamic lift is determined by the speed of the airfoil through the air, the advancing blade produces more lift than the retreating blade.
