Gas generator arrangement

A method and an arrangement to determine the lowest speed at which an activating pin activates a detonator, this being achieved by a hydraulic medium, the viscous property of which is used to control the transfer of energy from the activating pin to the detonator.

Igniting device

The present invention relates to a general method for increasing the energy conversion from metal-containing rocket and ramjet propellants. According to the invention, this is achieved by means of combining the combustion of the fuel with exothermic intermetallic alloying reactions between components incorporated in the fuel. The invention also concerns rocket and ramjet propellants formulated in accordance with the abovementioned method.

Ramjet propellants

A firing pin initiated primer intended to withstand extreme loading forces, includes a capsule having an opening defined by a continuous, deformable side wall and being deformable by the firing pin impacting upon the capsule at the opposite end thereof, an anvil surrounded the capsule, and having an upper portion with a cross section substantially corresponding to that of the capsule, an unbroken lower suppport surface facing the capsule, at the end opposite to the opening and a sealing surface adjacent to the support surface, at least one radial channel formed in the anvil adjacent the sealing surface and extending from the periphery towards the center and converging into an axial channel defined in the anvil, a compartment defined by the supporting surface and bottom and side walls of the capsule and containing a pyrocharge therein, which has the entire upper surface abutting the unbroken support surface of the anvil, and at least one gap formed longitudinally outside of the capsule allowing for the partial deformation of the side wall of the capsule outwardly into the gap upon ignition of the pyrocharge so that the flame jets of the pyrocharge may pass the sealing surface and reach into the at least one radial channel.

The disclosure relates to a pyrotechnical delay charge which may be mixed in water, comprising

Pyrotechnical delay charge

The disclosure relates to a method of producing pyrotechnical charges by mixing and granulating the included components in water, a considerable advantage from the point of view of safety. The method according to the invention also makes it possible to vary the percentage concentration of the included components so that the obtained pyrotechnical charges can either be used as delay charges or as ignition charges. Since, moreover, an acrylate binder is included, they will obtain superior mechanical strength properties.
