Abstract (en)
[origin: EP2075525A1] The pyrotechnic cutting cord (1) useful in military aircrafts and launchers, comprises an explosive material (5) disposed in a casing (2), and a metallic profile that forms a coating of the cut and is applied against the explosive material. The casing comprises two distinct parts assembled one after the other. The two distinct parts include a thin rear part or a covering (2a), and a thick front part (2b). The front part comprises two lateral wings (3a, 3b) forming a support for the covering and connected by a median zone that forms the coating of the cut. The pyrotechnic cutting cord (1) useful in military aircrafts and launchers, comprises an explosive material (5) disposed in a casing (2), and a metallic profile that forms a coating of the cut and is applied against the explosive material. The casing comprises two distinct parts assembled one after the other. The two distinct parts include a thin rear part or a covering (2a), and a thick front part (2b). The front part comprises two lateral wings (3a, 3b) forming a support for the covering and connected by a median zone that forms the coating of the cut, and is constituted by the metallic profile. The covering has a constant thickness, and is made of plastic or a composite material. The explosive material is applied in the form of a narrow sheet on the median zone of the front part. The narrow sheet is maintained in a place by the covering. An independent claim is included for a process for the fabrication of a cutting cord.
