The theory of a body striking a fluid began intensively developing due to the tasks of hydroplanes landing. For the recent years the study of a stroke and submersion of bodies into fluid became even more current. We face them in the process of strength calculation of ship hulls and other structures in modern technology. These tasks solution represents great mathematical difficulty even in case of the mentioned simplifications. These difficulties emerge due to the unsteady character of fluid motion in case of body submersion, and also jet and spray phenomena, which lead to discontinuous motions. On the basis of G.V. Logvinovich’s concept the problem of loads determination with consideration for air gap is solved for both a body and reservoir enclosing structures when a body falls into a fluid. Numerical method is based on the decay of an arbitrary discontinuity.
