Abstract

FIELD: rocketry; solid propellant igniters. SUBSTANCE: ignition chamber has housing, power grains and electric primer. Provided in housing between powder grains and electric primer is partition. Circular expansion chamber mounted on outer surface of housing is brought into communication with chambers of electric primer and powder grains through radial holes provided in housing wall. EFFECT: enhanced stability of operation of ignition chamber due to avoidance of destruction of powder charge through absence of direct action of electric primer gases on grains of ignition charge.

Изобретение относится к области ракетной техники, в частности к воспламенителям твердого топлива. Задачей изобретения является повышение стабильности работы воспламенительной камеры за счет устранения разрушения воспламенительного порохового заряда путем исключения прямого воздействия газов электрозапала на шашки воспламенительного заряда. Воспламенительная камера содержит корпус, пороховые шашки и электрозапал. В корпусе между шашками и электрозапалом выполнена перегородка, на наружной поверхности корпуса установлена кольцевая камера расширения, сообщающаяся с полостями электрозапала и шашек радиальными отверстиями, выполненными в стенке корпуса.The invention relates to the field of rocket technology, in particular to igniters of solid fuels. The objective of the invention is to increase the stability of the igniter chamber by eliminating the destruction of the igniter powder charge by eliminating the direct effect of electric fuse gases on the igniter charge checkers. The ignition chamber contains a housing, powder bombs and an electric fuse. In the case between the checkers and the electric fuse, a partition is made, an annular expansion chamber is installed on the outer surface of the casing, communicating with the cavities of the electric fuse and checkers with radial holes made in the wall of the casing.
