Explain Dissymmetry of lift? Definition, Compensated for, Tandem rotor considerations.
Definition: The difference in lift produced by the advancing and retreating blades. The advancing blade produces has higher relative wind and produces more lift.
Compensated for: Blade flapping (low airspeed) / LCT cyclic feather (high airspeed)Tandem Rotor Considerations: LCT’s are provided to accomplish cyclic feathering at designated airspeed (70 knots). This allows for increased airspeed and level fuselage attitude at high airspeed. If the cyclic-feathering system fails to properly feather the blades at higher airspeeds, greater blade-flapping angles and nose-low flight attitudes induce bending forces on the rotor-driving mechanisms.
