Solid fuel rocket motor - has combustion chamber split into different chambers by perforated transverse walls

摘要

The solid fuel rocket motor has a sieve-type body in the combustion chamber in front of the jet opening. The sieve orifices are smaller than the dimensions of the powdrous drive charge but allow a sufficient pressure balance. The drive charge fitted in the combustion chamber consists of leaves or strips. - The combustion chamber is split into different chambers (11) by perforated transverse wells (5) whose perforations (10) are smaller than the dimensions of the charge. The transverse walls (5) are fixed on a carrier element (4) which is firmly connected with the sieve-type body (3). A middle tube can act as common carrier element (4) for the transverse walls.
