When the advancing blade flaps up due to the increase of lift the pitch flap coupling will extract pitch from the blade reducing its’ lift. Conversely if the retreating blade flaps down pitch is increased due to pitch flap coupling thus equalizing the lift.
WebAug 12, 2024 · Dissymmetry of Lift is corrected by the teetering and feathering of the main rotor. The teetering in this statement is actually flapping away from the direction of travel, and the feathering comes from the cyclic input to stop it from happening. There are forces felt through feedback from the rotor system. WebDissymmetry of lift is an aerodynamic phenomenon caused by the rotation of a helicopter's rotors in forward flight. Rotor blades provide lift proportional to the amount of air flowing over them.
http://www.copters.com/aero/lift_dissymetry.html WebDissymmetry of lift is the differential (unequal) lift between advancing and retreating halves of the rotor disk caused by the different wind flow velocity across each half. This difference in lift would cause the helicopter to be uncontrollable in any situation other than hovering in a calm wind.
WebThis condition is defined as dissymmetry of lift. See figure 5-4. Left uncompensated, a helicopter with a counterclockwise main rotor blade rotation would roll to the left because of the difference in lift. To prevent …
