The method of descent of the separating part of the stage of a rocket for space purposes and a device for its implementation

摘要

FIELD: aviation.SUBSTANCE: method of lowering the spent part (SP) of SMV submissile on the liquid components of rocket fuel to the predetermined drop region is based on stabilization and orientation of SP due to the energy of unprocessed residual liquid propellant components on the basis of their gasification and feeding to the waste nozzles of gas-reactive system. Gasification products are used to inject them into the boundary layer. The coordinates of the point, the direction of injection and the mass-flow rate of gasification products through the entry system into the boundary layer are determined from the condition for formation of maximum total control effect realized by the control nozzles of gas-reactive system and the nozzles of gas injection system into the boundary layer of SP. In device for implementing the method, nozzles of gas-reactive system and nozzles of gasification products injection into the boundary layer for each tank are introduced to the separating part of submissile, connected by lines with adjustable valves.EFFECT: increasing efficiency while lowering the SP of submissile of SMV.2 cl, 2 dwg
