SOLID-PROPELLANT ROCKET ENGINE HOUSING Russian patent published in 2020 - IPC F02K9/34 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely, to solid-propellant rocket engines, and can be used in development of solid propellant rocket engines. Solid-propellant rocket engine housing comprises bottom with central hole and elastic collar having part bent inward and located in the area of central hole and made with possibility of installation of process wedge between bottom and bent part of resilient collar. In order to form solid fuel charge, collar is equipped with process retainer dismantled after completion of charge formation. Retainer is located on the part of the cuff bent inside the body from the side of the central hole, has the shape of a cylinder and is equipped on its end with a bulge, made with possibility of fixation in the tooling.

EFFECT: invention allows improving solid propellant engine design reliability and quality of its fuel filling process due to exclusion of fuel mass ingress into the pre-arranged cavity.
