Roll Damping Coefficient

  1. Jan 29, 2014 #1
    Hello, I am new to Aerodynamics and am having trouble understanding what exactly the roll damping derivative is.

    The roll damping derivative is a measure of the change in rolling moment coefficient with respect to nondimensional roll rate and is usually negative.

    Does that mean a glider (which isn't expected to roll) has a really high roll damping derivative where an FA-18 fighter has a lower roll damping coefficient so that it can perform evasive maneuvers?

    Thanks a lot!
