Temperature-insensitive propellant powder

摘要

Propellant powder with grains containing holes opening to the outside but sealed with a plug, in which the plug shows a temperature-dependent mobility, i.e. a mobility which is greater at lower usage temperatures than at higher temperatures, resulting in faster hole burning at lower temperatures. An independent claim is also included for a method for the production of propellant powder with perforated grains by introducing plugs of solid material as above into the openings.
