The purpose of researches - working out of a method of calculation of design parameters of system of giving of fuel from tanks of the devices which operating conditions provide the limited break of a gas phase through mesh elements of means of maintenance сплошности fuel. A method of researches - mathematical and physical modeling of real processes. The mathematical model of break of a gas phase through mesh elements is constructed. The algorithm is developed and numerical calculations of interaction of an interface of phases with a mesh element in the conditions of action of power loading which exceeds borders of its keeping ability are carried out. The physical model is constructed, the technique is developed and experiments on studying of interaction of a free surface of a liquid with a mesh element in the conditions of break through it of a gas phase are made. The engineering technique of calculations of design parameters of mesh elements in the conditions of break through them of a gas phase is developed. The method of calculation of design parameters of system of giving of fuel which is connected with functioning of means of maintenance fuel continuity in a critical mode is developed. Recommendations for choice optimum design parameters mesh elements in the conditions of their work in after critical an overload mode are made. The received theoretical and experimental results correspond to existing results on studying of working capacity of means of maintenance fuel continuity of mesh type in the conditions of normal functioning and are for the first time received for functioning of these elements in critical conditions. Results can be used by working out and improvement of systems of giving of fuel in avia - and rocket production.
