<p>The propellant element (16) serves as a monolithic helix provided with complete coils. A solid propellant includes polymer material as main component and filling material. The filling material is electrically conducting, semi-conductive and/or non-conductive filling material such as molybdenum disulfide, aluminum oxide, silicon carbide, zinc oxide and boron nitride. The polymer material consists of fluoropolymers, polyethylene, polypropylene, polyoxymethylene, polyacetal, polyethylene terephtalate and polybutylene terephthalate and copolymers. An independent claim is also included for a method for manufacturing a solid propellant element.</p> |
