2. Dissymmetry of lift - Wikipedia

   en.wikipedia.org/wiki/Dissymmetry_of_lift

   Since the lift generated by an aerofoil increases as its relative airspeed increases, on a forward-moving helicopter the blade-tip at position A produces more lift than that at point B. So the rotor disc produces more lift on the right hand side than on the left hand side (for an American-style helicopter). This imbalance is "dissymmetry of lift".

   The airport also has a helipad for helicopter operations. Designated as helipad H1, it measures 40 x 40 ft (12 x 12 m) and is paved with asphalt. [11] [12] In 2020, the airport's main runway received rehabilitations to continue offering safe operations. [13]

4. Flapback - Wikipedia

   en.wikipedia.org/wiki/Flapback

   In normal operating circumstances, forward flight results in flapback caused by dissymmetry of lift and the transverse flow effect. [2]: 2–20 Dissymmetry of lift is where the forward-moving rotor blade has a faster airspeed, so it generates more lift, which would cause the rotor disc to tilt to the side. To prevent this the forward-moving ...

5. Coaxial-rotor aircraft - Wikipedia

   en.wikipedia.org/wiki/Coaxial-rotor_aircraft

   Dissymmetry 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. When viewed from above, the rotor blades move in the direction of flight for half of the rotation (advancing half), and then move in the opposite ...

7. Retreating blade stall - Wikipedia

   en.wikipedia.org/wiki/Retreating_blade_stall

   Retreating blade stall is a hazardous flight condition in helicopters and other rotary wing aircraft, where the retreating rotor blade has a lower relative blade speed, combined with an increased angle of attack, causing a stall and loss of lift. Retreating blade stall is the primary limiting factor of a helicopter's never exceed speed, V NE. [1]
