All-Aluminum Transverse Platelet Injector

reportActive / Technical Report | Accession Number: ADD004677 | Open PDF

Abstract:

Multielement injectors for bipropellant rocket engines fabricated from photoetched aluminum platelets which are diffusion bonded to each other with the bonded faceplate assembly electron beam welded to a machined aluminum injector body. The surface contaminants as well as the inherent aluminum oxide are first removed from the platelets. The platelets are then stacked and subjected to 300 psia load at a temperature of 1070 - 1080 deg F. The pressure and temperature are maintained for three hours using a vacuum furnace evacuated to .0001 TORR or better. The finished bonded faceplate is then joined to the injector body using electron beam welding.
