In the article has been chosen and simulated the dynamic characteristics of a fuel tank during longitudinal oscillations. In this study we shall proposed methods for determining the dynamic properties during longitudinal oscillations of fuel tanks for structurally similar models. The computation results enable to determine load in attachment points of fuel tank, and reduced masses of the liquid in the fuel tank for different natural oscillation frequencies. The calculations show that in a steady state condition in the absence of longitudinal accelerations, and small amplitudes of liquid oscillations, when we exclude temperature changes (adiabatic thermal insulation), the decrement of free oscillations obtained as a result of computations remains unchanged and is equal to 1.
