DEVICE FOR INITIATION Russian patent published in 2006 - IPC F42B3/10 

FIELD: pyrotechnics, structures of igniters.

SUBSTANCE: ignition and initiating charges made of pyrotechnical compositions are installed in the body in alignment through a partition. The initiating charge is made of a pyrotechnical composition containing no gas, forming solid combustion products in the form of two elements connected by a duct. The cross-section area of the initiating charge element engageable with the partition is commensurable with the cross-section area of the ignition charge. The partition may be made in the form of a plate, both massive and with peripheral holes or slots. The element of the initiating charge engageable with the partition and the connecting duct may be cylinder=shaped with a correlation of dimensions d=(0.1-0.3)*D and d/L=0.2-1.0, where: d - the diameter of the connecting duct; D - the diameter of the initiation charge element engageable with the partition; L - the length of the connecting duct.

EFFECT: the actuation time makes up approx.0.01s; possibility of device cut-off from the environment; possibility of adjustment of the actuation time.
