Calculation of the Power of a Heat Source Necessary to Destruct an Obstacle

A. N. Pervyshin

ABSTRACT

Generalized results of theoretical and experimental studies of the process of obstacle material heating to the assigned temperature by combustion products issuing from the generator of supersonic jets are presented. In all types of heat sources this process usually precedes onset of material cutting, but it also has an individual engineering implementation, e.g., in thermal treatment. A method for calculation of a minimum power of a heat source or fuel consumption in generators of supersonic jets depending on a thickness and thermophysical properties of the material is suggested and confirmed experimentally. Energy parameters of a heat source which provide cutting of a material of any thickness are determined and corresponding restrictions for sources of smaller power are given.
