Rolling Moment Calculator

The rolling moment in aerodynamics refers to the rotational force or torque around the longitudinal axis of an aircraft. It is generated by asymmetrical lift distribution across the wings, typically controlled by aileron deflection. The rolling moment influences the aircraft’s rotation around its longitudinal axis, resulting in a rolling motion. The formula to calculate Rolling moment as follows:

Where:

• $L$ is the rolling moment (Nm),
• $q$ is the dynamic pressure (Pa),
• $S$ is the reference area (m²),
• L_c​ is the characteristic length (m),
• C_l​ is the rolling moment coefficient (dimensionless).
