METHOD OF PRODUCING END BURNING SOLID PROPELLANT CHARGE Russian patent published in 2011 - IPC B01F3/12 C06B21/00 

FIELD: process engineering.

SUBSTANCE: invention relates to mixing of liquid and powder substances and may be used in making multicomponent mixes. Solid propellant components are mixed in mixer. Produced mix is fed into shaping case, shaped by piston-like device, cured and removed from said case. Note here that two or more fluid compositions are produced from solid propellant components. Each composition with flow rate varying according to definite law is fed into gasdynamic spray cone. Compositions are dispersed, mixed and homogenised in said cone. Produced composition is fed, layer-by-layer, into shaping case, shaped by piston-like device, cured and removed from said case.

EFFECT: control over solid propellant components content over end burning charge length.
