What is the upward bending of rotor blades caused by lift and centrifugal forces called?

• A. Airfoil effect
• B. Blade flexing
• C. Coning
• D. Torque bend

Answer: (C)

The upward bending of rotor blades caused by lift and centrifugal forces is known as coning. This phenomenon occurs when the rotor blades experience both aerodynamic lift and the outward force generated by rotation, causing them to flex upward. The result is a conical shape formed by the rotor blades as they maintain their position due to these opposing forces. This bending is essential to ensure the rotor system functions efficiently and safely. Understanding coning is crucial in aviation and rotorcraft design, as it impacts performance, stability, and the overall dynamics of rotor systems. Recognizing this concept also helps in understanding how rotor blades interact with aerodynamic forces in flight, emphasizing the importance of physical forces at play in aviation.
