Abstract

The spiral-shaped propulsion charge is wound on a central shaft and is used esp. for rocket propulsion. The charge consists of a flexible belt with several windings on which fuel rods are fixed parallel to the central shaft while using a reduced fixing face. The fuel rods within the charge are in contact with two windings on both side. The fuel rods are fixed in the same straight section of the charge on a single flexible belt. Alternatively, the fuel rods are fixed to two flexible belts which are in contact. Each flexible belt has restricting properties w.r.t. the combustion properties of the fuel rods.
