Abstract
A Fluid Injection System for rocket engines is disclosed, which comprises methods and apparatus for combining a ring-type rocket injector body and face into a single cast part, eliminating all subassemblies, their associated fabrication and integration costs, and thereby significantly lowering injector costs while increasing injector quality and reliability. The injectors may be used in rocket engines and auxiliary propulsion devices such as gas generators for a variety of applications including rockets, missiles, space launch vehicles, space vehicles, and Lunar, asteroid, and Mars lander vehicles.
Claims17
A method comprising the steps of:
- creating a casting pattern and a pre-formed ceramic core for a ring-type rocket engine injector (24);
