Results of measurements in a wind tunnel of pressure distributions on schematic duplicated models of underwater part of transport ships with various bows and after ends are submitted in the report. The electrohydrodynamical analogy method was employed to receive distributions of tangent velocities and to calculate pressure distributions on surfaces of the same models in an ideal liquid. Epures of pressure distributions in ideal and viscous liquid are compared among themselves and projections of all pressure components on the longitudinal axis of model are calculated, and their integration is fulfilled. The contribution of various components of the common drag is evaluated separately for bow and an after end. Results of the carried out researches are compared to results of direct drag measurements of the same models on aerodynamic balance.
