MULTIPLE INCLUSION SOLID PROPULSION SYSTEMS AND METHOD OF ITS MULTIPLE INCLUSION Russian patent published in 2019 - IPC F02K9/94 F02K9/95 F02K9/86 

FIELD: rocket equipment.

SUBSTANCE: invention relates to rocket science, particularly, to development of booster blocks based on solid propulsion systems, and is aimed at perfection of their design. Solid propulsion systems for space rocket multiple inclusion comprises main combustion chamber with solid combustion fuel charge of end combustion, cover with places of attachment of nozzle control units, igniting device and pressure sensors, connected to combustion chamber, an igniting device connected to a pyrocartridge, nozzle control units with controlled critical sections, a steering drive for adjusting the size of the critical section of the nozzle control units, one or more pressure sensors communicating with the inner cavity of the main combustion chamber and connected to the control system. Igniting device is made in the form of several gas generators with solid fuel charges connected through check valves to the receiver communicating with the main combustion chamber through the gas duct coaxial to the main combustion chamber. For multiple inclusion of solid propulsion systems before each subsequent switching on the basis of data obtained by means of pressure sensors on the actual pressure cyclogram realized on previous inclusions, SU calculates required total area of critical sections of nozzle control units, providing required pressure in combustion chamber of solid propulsion plant, according to protected by this invention formula, then, by means of steering drive, critical sections of nozzle control units are set to position providing calculated total area of critical sections.

EFFECT: group of inventions improves reliability of solid propulsion system of multiple connection.
