FIELD: rocketry. ^ SUBSTANCE: rocket comprising a payload coupled with an engine having a combustion chamber wherein a solid-propellant charge is disposed, and a nozzle cluster. Said nozzle cluster is arranged at the engine front end and said combustion chamber is made in the form of a cup and divided into two cavities by a partition with gas ducts, the total area of them is determined on the basis of mathematical expressions. Said partition in the combustion chamber is arranged behind the nozzle cluster, and the charge is placed into the combustion chamber behind the partition at the rear end side. Fuel combustion products in the combustion chamber are bled off in the direction of movement of the rocket. A pressure difference is created therein according to the first mathematical expression. Compressing forces that acts on the charge are compensated thereby, thus equilibrating the action of inertial forces of an axial acceleration that acts on the rocket. The effect is achieved in the rocket engine, wherein an inserted solid-propellant charge is used, due to excluding the possibility of destroying the charge. ^ EFFECT: improving the reliability of a propulsion rocket. ^ 1 dwg |
