When the airframe begins to rock back and forth from the oscillation, the oscillations can reinforce each other and cause the rotor's center of gravity to spiral away from the axis of rotation to a point beyond the compensating ability of the damping system. Meer weergeven Ground resonance is an imbalance in the rotation of a helicopter rotor when the blades become bunched up on one side of their rotational plane and cause an oscillation in phase with the frequency of the rocking … Meer weergeven Articulated rotor systems with drag hinges allow each individual blade to advance or lag in its rotation to compensate for stress on the blade … Meer weergeven • Helicopter flight controls • Helicopter pilotage • Helicopter rotor • Aeronautical engineering Meer weergeven Proper maintenance of the helicopter's damping system components can prevent ground resonance from taking hold. When it does occur, recovery is often possible if action is taken quickly. If sufficient rotor RPM exists, immediate takeoff can restore rotor … Meer weergeven • Video of a Brazilian rescue AS350BA breaking apart after landing due to ground resonance. • Chinook helicopter with wheeled landing gear ground resonance - side view video Meer weergeven WebThis is just for micro RC helicopters. If you fly larger single rotor birds, you want the ball links tight and secure, but for the upper head on a micro coaxial or micro single rotor, a little looseness is desirable to eliminate toilet bowl effect. It is a fine line between too loose and coming off in flight, or a little to tight causing TBE.
