Durability Testing of an Iridium-Plated Storable Rocket Engine Injector.

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 N2O4/MMH 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 AFAL's testing, including the analysis and evaluation of the injector orifice corrosion/erosion. Keywords: Nitrogen tetroxide; Monomethyl hydrazine; XLR-132 Engines; Liquid propellant rocket engines.
