Analytical investigation is made of flutter phenomenon that may occur in propeller nacelle wing combination; one of objects of investigation is to isolate and show influence of those parameters which appear to be most strongly linked with this whirl-type instability; various combinations of pitch and yaw stiffnesses of nacelle, structural damping, and propeller speed are considered; part of study is devoted to examination of propeller aerodynamics; comparison made of analytically determined critical conditions with results obtained in wind tunnel tests.
