ROCKET AND SOLID-PROPELLANT ROCKET ENGINE Russian patent published in 2017 - IPC F02K9/08 F42B15/36 F02K9/28 

FIELD: engines and pumps.

SUBSTANCE: rocket contains a pulling solid-propellant rocket engine and a pushing rocket engine. The pulling solid-propellant rocket engine includes a nozzle cluster formed by several inclined nozzles evenly distributed around the circumference, mounted on the rear bottom, as well as a rear joint assembly. A bucket is attached to the solid-propellant rocket engine housing, with an inner cylindrical surface of which a pallet with a payload contacts, associated with the pushing rocket engine. The length and mass of the solid-propellant rocket engine exceed the length and mass of the pushing rocket engine. Another invention relates to a soild-propellant rocket engine comprising a housing with bottoms, a rear joint assembly, a nozzle cluster, and a bucket connected to the front bottom. A pallet with a payload contacts with the inner cylindrical surface of the bucket. The bucket is connected to the rear bottom and has an open rear end. The cross-sectional area of the rear joint assembly is determined by the pull-bending load equal to the sum of the thrust of the soild-propellant rocket engine and flight loads.

EFFECT: group of inventions allows to increase the energy mass efficiency of a rocket and solid-propellant rocket engine, to simplify their design and increase reliability, to minimize the dimensions of the rocket in its initial state.
