Реферат: The main goal of this report is to prove an absolute instability for steady-state three-dimensional flows of an ideal compressible fluid entirely occupying a certain volume with quiescent solid impenetrable boundary under small spatial perturbations in absence of external mass forces. Also, we will receive constructive conditions for linear practical instability and, as a sequence, the a priori exponential lower estimate for growth in time of the considered perturbations.
