DEVICE FOR GASIFICATION OF SOLID HYDROCARBONS FOR RAMJET ENGINE Russian patent published in 2019 - IPC F02K7/08 F02K9/08 

FIELD: machine building.

SUBSTANCE: solid hydrocarbons gasification device for ramjet engine comprises a solid-fuel gas generator with an outlet branch pipe and an igniter and a gasifier having a hollow housing with inlet and outlet cavities located on opposite sides of the housing, a working chamber with inlet and outlet channels, filled with solid hydrocarbon substance, and a control element with a drive connected to the outlet cavity of the housing. Solid-fuel gas generator is connected to inlet cavity of outlet by means of outlet branch pipe. Outlet cavity of housing is connected to combustion chamber of engine. Gasifier is equipped with an acoustic resonator with a pneumatic drive installed in the inlet cavity of the case opposite to the outlet branch pipe of the solid-fuel gas generator. Working chamber of gasifier is made with cylindrical side surface, on which there are at least two through longitudinal slots, which are output channels of working chamber, and is equipped on the side of the outlet cavity of the housing, with a gas-tight end wall and located on the side of the inlet cavity of the housing, with a perforated end wall, perforation holes of which are input channels of the working chamber. Regulating element is made in the form of a cylindrical shell conjugated by its inner surface with a cylindrical side surface of the working chamber. Cylindrical shell ring is equipped with at least two through helical slots made intersecting with longitudinal slots of working chamber. Cylindrical ring drive is rotary.

EFFECT: invention provides higher efficiency of gasifier due to optimization of parameters of sublimation of solid hydrocarbon substance by successive layer-by-layer treatment of solid hydrocarbon substance by flow of high-temperature combustion products.
