The transmission matrix method is used to determine the dynamic characteristics (natural frequencies and the associated mode shapes) of rotor blades. The problems treated are combined flapwise bending, chordwise bending, and torsion of twisted non-uniform blades and its special subcases. The orthogonality relations that exist between the natural modes are derived. The method is appealing because of its simplicity for programming for digital computer calculations and also the inputs are generated very easily since they are merely the coefficients of the differential equations of motion.
