Abstract
Ziarno ma co najmniej jedną wewnętrzną przegrodę o właściwościach termoizolacyjnych wbudowaną w osiowo symetryczne ziarno, wydłużającą drogę spalania stałego materiału pędnego względem dyszy silnika rakietowego. Przegrodę stanowi co najmniej jedna płyta (3) o średnicy mniejszej od średnicy ziarna, usytuowana koncentrycznie w osi ziarna. W innym wykonaniu przegrodę stanowi co najmniej jeden pierścień w kształcie odcinka rury o długości mniejszej od długości ziarna, usytuowany koncentrycznie w osi ziania i przylegający dolną krawędzią do podstawy ziarna od strony dyszy (6).The grain has at least one internal partition with thermal insulation properties built into the axially symmetrical grain, extending the combustion path of solid propellant relative to the rocket engine nozzle. The partition is at least one plate (3) with a diameter smaller than the diameter of the grain, located concentrically in the grain axis. In another embodiment, the septum is at least one ring in the shape of a section of pipe with a length less than the length of the grain, located concentrically in the axis of yarn and adhering with the bottom edge to the grain base from the nozzle side (6).
