A general analysis of the added mass and damping of a marine propeller in all modes of rigid body vibration is presented. This derivation assumes that the pressure distribution on a propeller blade due to a unit heave oscillation or unit pitch oscillation about the midchord point can be obtained by two-dimensional thin foil theory, lifting-line theory, or lifting-surface theory. These results show that eighteen coefficients are needed to completely characterize the added mass and damping of a propeller. The use of two-dimensional thin foil theory and lifting-line theory to obtain the pressure distribution on a propeller blade due to a unit heave oscillation or unit pitch oscillation are reviewed. These results have been utilized in the PRAMAD computer program which calculates the added mass and damping of a vibrating propeller.
