Instances of lagging instability on rotors were encountered in whirl stand tests of full scale blades; applications of theory relating to mechanism of these instabilities to helicopters for which actual flight data exists resulted in contradictions; additional term arising from aerodynamic damping of lag motion is shown to have significant stabilizing effect and improves degree of correlation.
