Abstract
A single-piece thermally isolated multi-point injector for a hydrazine fuel catalytic gas generator having a series of integral feed tubes each with a fuel passage and with the fuel inlet ends thereof spaced apart for ease of manufacture and inspection and associated with a distribution manifold. The feed tubes are arranged in spaced-apart circular arrays to facilitate formation thereof from an investment casting or by radial electrochemical machining cuts. The fuel injector retains the thermal isolation features of a welded or brazed capillary tube injector, but eliminates leakage points encountered in such a structure. The outlet end of each feed tube has a porous member associated therewith to obtain a uniform flow path of hydrazine fuel in all directions onto a catalyst bed.
