Lebedev В. Determination of the power characteristics of exothermal rods at repair and salvaging of ships

The activity is dedicated to idealized and experimental analysis of legitimacies of thermoexchange at combustion of exothermal cutting and welding rods, overland and underwater, at salvaging and repair of ships with the purposes of scientifically - reasonable calculation of indispensable power of such rods, their reasonable designing and creation exothermal means, with which one could ensure a required power. The analytical researches of process of thermoexchange of a burning rod over and underwater have given new scientific results, having shown, that heat rejections are connected to different legitimacies of thermoexchange - at film, bubble and combined boiling of water about a burning rod and at heat convection without change of a modular condition. These researches have enabled the reasonable calculation of power and efficiency of exothermal rods for underwater cutting. In activity of the researches on legitimacies of combustion of exothermal mixtures are conducted, their classification and scientific technique of calculation of a component structure, for maintenance of a required power of a rod are given.
