I’ve had rotor brake failures during HEMS missions in high winds, and it can really screw with the plan, as it could prohibit a shutdown, depending on the local wind speed 💨 Why? Rotor blade dynamics change a lot during shutdown. When a helicopter rotor system is at operating RPM, the rotor blades are kept “stiff” and stable primarily by centrifugal force: 🔸 The blades are pulled outward 🔸 In-plane stiffness is high 🔸 Aerodynamic disturbances are relatively well damped But during shutdown, r

Helicopter Aerodynamics Dissymmetry of lift Dissymmetry of lift is the unequal lift produced by the advancing and retreating halves of a helicopter rotor disc during forward flight. The Cause: Airspeed Differential In a hover, all rotor blades move at the same speed relative to the air, creating uniform lift. However, as the helicopter moves forward: Advancing Blade: Moves in the same direction as the helicopter. Its total airspeed is the sum of the blade's rotational speed and the helicopter’s
