Injector assembly for a rocket engine

摘要

A cap for a liquid propellant injection assembly of a rocket engine includes a cap body and a valve assembly. The cap body extends between first and second ends. The cap body has a bore that fluidly connects one or more inlets to an outlet. The inlets are disposed in a tubular sidewall of the cap body. The outlet is disposed in the second end of the cap body. The valve assembly includes a valve cap disposed around the first end of the cap body. The valve assembly is adapted to selectively regulate flow of a propellant through the inlets in the cap body as a function of pressure exerted by the propellant against the valve assembly.

1. An injector for a liquid propellant injection assembly of a rocket engine, comprising:
a swirl element extending between first and second ends, the swirl element has a bore that connects a secondary orifice to an outlet, the secondary orifice is disposed in a sidewall of the swirl element, the outlet is disposed in the second end of the swirl element, and the secondary orifice extends along an axis, the axis inclined relative to a tangential plane of an outer surface of the sidewall; and a pressure actuated cap disposed around the first end of the swirl element, the pressure actuated cap is adapted to regulate flow of a propellant through the secondary orifice as a function of pressure exerted by the propellant against the pressure actuated cap.
