Abstract

This article presents an overview of current research and material requirements for metal-matrix composite (MMC) technologies being developed for liquid rocket engines (LRE). Developments in LRE technology for the U.S. Air Force are being tracked and planned through the integrated high payoff rocket propulsion technologies program (IHPRPT). Current efforts and research requirements for three types of MMC systems are discussed: aluminum-, copper-, and nickel-matrix material systems. Potential applications include turbopump housings, rotating machinery, and high-stiffness flanges and ductwork.
