Injector for injecting propellant in combustion chamber of rocket engine, has pipe for injecting propellant into combustion chamber, porous and permeable body received in pipe, and dismountable sleeve forming external wall of pipe

摘要

The injector (201) has a first pipe (204) for injecting a propellant (E1) into a combustion chamber. A porous and permeable body (212) is received in the pipe. A dismountable sleeve (203) forms an external wall of the pipe. A second pipe (205) is arranged coaxially and internally adjacent to the first pipe to inject another propellant (E2) into the combustion chamber. A third pipe (206) is arranged coaxially and internally adjacent to the second pipe, where the pipes comprise annular sections. An independent claim is also included for a method for calibrating a flow of injecting a propellant in a combustion chamber through a pipe of an injection element.
