WebJan 23, 2024 · Atmospheric turbulence introduces significant broadband vibrations at the main rotor hub which carry a considerable amount of energy into the non-rotating helicopter structure. Frequencies... WebConing In order for a helicopter to generate lift, the rotor blades must be turning to create a relative wind that is opposite the direction of rotor system rotation. The rotation of the rotor system also creates centrifugal force, which tends to pull the blades straight outward from the main rotor hub.

WebOn helicopters with just two blades (as with the R22) both blades teeter up and down together like a see-saw. Therefore no, the R22 does not have flapping hinges. Those two hinges on the ends of the R22's rotor hub are to allow the blades to cone (or bend up) as they support the weight of the helicopter once it lifts off the ground. WebThe degree of “coning” is the result of the combination of centrifugal force and lift on each blade causing each rotor blade to assume a slight up upwards tilt a few degrees.

"Coning is a phenomenon which affects helicopter rotor discs. The tips of the helicopter rotor blades move faster through the air than the parts of the blades near the hub, so they generate more lift, which pushes the tips of the blades upwards, resulting in a slight cone shape to the rotor disc. This is balanced by centrifugal force. If rotor RPM drops too low, the rotor blades fold up with no chance of recovery. " - Coning helicopter

For most helicopters, this point is between 1.5 and 2.0 g. Pilots should be prepared for dig-in during aggressive aft cyclic inputs, especially during break turns.

WebConing is a phenomenon which affects helicopter rotor discs. The tips of the helicopter rotor blades move faster through the air than the parts of the blades near the hub, so they generate more lift, which pushes the tips of the blades upwards, resulting in a slight cone shape to the rotor disc. WebConing, explained. A helicopter’s rotor disk assumes a conical shape as lift overcomes centrifugal force and the tips of the rotor blades rise in response.
