Abstract: FIELD: physics. 
     SUBSTANCE: invention relates to control of vessels and can be used for prediction of trajectories of underwater vehicles performing complex maneuvering. Method for determination of damping hydrodynamic characteristics of underwater object, consists in the fact that near its three-dimensional electronic model inner spherical computational grid is formed with center of sphere coinciding with point of rotation of underwater object. Inner spherical computational grid is made with possibility of rotation together with three-dimensional electronic model of underwater object relative to external computation grid. Around the impeller water-jet propeller, a cylindrical computer grid is formed with the possibility of rotation of the water-propellant propulsor impeller relative to the inner spherical computer grid. At that, distribution of flow velocity and pressure fields is determined in calculation area formed by internal, external and cylindrical computer grids. Velocity of fluid motion at input flow boundary of design area is set equal to linear speed of underwater object, as well as corresponding rotation frequency of impeller of water-jet propeller. Submersible object oscillations are successively set in trim, drift and roll angles. As a result, non-stationary hydrodynamic effects on underwater object with operating water-jet propeller are determined, these relationships are analyzed and hydrodynamic effects values at trim, drift and roll angles equal to zero are determined. Then damping hydrodynamic characteristics of underwater object with operating water-jet propeller are determined. 
     EFFECT: higher safety of underwater object control when performing complex maneuvering, higher accuracy of underwater object control.
