Yawing moment due to the roll rate calculator

In flight mechanics, the yawing moment due to the roll rate refers to the rotational force or moment that is generated around the vertical axis of an aircraft (yaw axis) as a result of a change in the aircraft’s roll rate. This phenomenon is a consequence of the complex interactions between the aircraft’s aerodynamic surfaces, its geometry, and its motion.

  • Yp” is the yawing moment due to the roll rate.
  • “QS” represents the dynamic pressure (0.5 * density * velocity^2), where “density” is the air density and “velocity” is the aircraft’s velocity.
  • “mu0” is the reference dynamic viscosity of the air.
  • “b” is the wingspan of the aircraft.
  • “Cyp” is the derivative of side force coefficient with respect to roll rate.
