Summary:

This note constitutes a general theoretical discussion of the damping factor in roll, together with the results of wind tunnel tests on the continuous rolling of a U.S.A.-30 airfoil. Two general formulas are derived for the damping of roll, each of which contains unavoidable indeterminate functions. Certain of these functions have been evaluated from the test data. Of chief interest is the deduction that the actual damping as experienced in flight differs from the damping as theoretically calculated by a function of the wing-tip pressure distribution, which is in turn largely influenced by the form of the wing-tip and by the rolling velocity.
