Abstract:

A series of hot firings were conducted at the Air Force Astronautics Lab. to evaluate the durability of an iridium plated, like-doublet, storable rocket engine injector. The injector was designed for N2O4MMH propellants and a chamber pressure of 1500 psia. Iridium plating failed to protect the injector face however, valuable insights into the attack mechanism were gained. This report presents the results of AFALs testing, including the analysis and evaluation of the injector orifice corrosionerosion. Keywords Nitrogen tetroxide Monomethyl hydrazine XLR-132 Engines Liquid propellant rocket engines.
