Liquid fuel rocket thrust regulator - has combustion chamber cooling channels with by pass regulated by sliding valve collar projections

摘要

A liquid fuel rocket has its injection head formed by two concentric parts separated by an annular gap each part having holes for the oxygen and fuel and regulated by a rotatable slide valve with corresponding holes for the fuel and oxygen, separated by the slide valve collar which projects into the annular gap. A bypass from the combustion chamber cooling channels is regulated by radial projections on the slide valve collar which closes the by pass in the one end position to give a minimum thrust and gradually opens the by pass to give a maximum thrust in the second end position.
