FIELD: engine building.

SUBSTANCE: invention relates to a structure of rocket engines of ballistic missiles and launch vehicles operating on solid dispersed bulk fuel. The rocket engine on bulk fuel, containing a case, a nozzle, solid fuel, is equipped with a fuel hopper of a consumable structure, a bottom of which is made in the form of a piston with the possibility of axial movement relatively to a shell of the hopper, as well as containing a combustion chamber with a nozzle and a sluice supply mechanism, fixed on the bottom, while a unit of the combustion chamber, the nozzle, and the sluice supply mechanism are connected to the bottom of the fuel hopper by means of a bearing installed coaxially with a traction axis of the nozzle, and the shell of the hopper is made in the form of tape winding embracing bulk fuel massif, wherein a lower end of the tape of the specified winding is passed through a sealing device into a cavity of the combustion chamber and next – through the nozzle to a mechanism for extending and cutting of the tape, installed on a cut of the nozzle.

EFFECT: invention provides an increase in the efficiency of an engine and an increase in operation time.
