Abstract
An active body is provided that includes at least one active mass block made of monobasic or polybasic high-energy materials such as a nitrocellulose mixture, for example, comprising approximately 60 percent nitroglycerin and 40 percent diethylene glycol dinitrate, which is provided with structures both on a surface and on an interior. In addition, the inner structures can be filled with an active mass substance. The ignition is triggered by a pyrotechnical primer composition, which initiates the active body, preferably from the inside.
Claims12
An active body comprising:
- at least one pyrotechnic active mass block having specific structures at or on a surface of the active body and in an interior of the active body, wherein said structures in said interior being formed of channels and/or cavities;
- said channels and/or cavities being filled with fine structured materials formed of active mass substances which are initiated by primer compositions,
- wherein the structures on the surface, which are formed as grooves and/or roughened texture, enlarge the surface depending on a pattern and a depth of the structures, and
- wherein the active mass block further comprises gas and/or temperature bridges between the channels or cavities in the interior of said active mass block, the gas and/or temperature bridges being formed by slits, perforations and/or bores.
