Abstract
A linear ignition fuze has a sheath, the inner surface of which has an irregular cross section such that the sheath is capable of forming a gas channel against a single strand core having a substantially circular (e.g. circular or elliptical) cross section. According to one embodiment of the invention, the sheath wall is of a non-uniform thickness having a cylindrical outer surface and a polygonal inner surface. The gap formed between the apexes of the polygonal inner surface and the substantially cylindrical core form the gas channels, while the contact between the side walls of the polygonal inner surface and the cylindrical core confine the core within the sheath.
