Researchers are today focusing their efforts on ambitious performance goals for turn-of-the-century military and civil aircraft propulsion systems, objectives set by projects such as the High Speed Civil Transport. One such programme co-ordinated by NASA and the DoD, the Integrated High-Performance Turbine Engine Technology Initiative, or IHPTET, seeks to double thrust-to-weight ratios to 20:1 by the year 2003. Tomorrow's aircraft engines will undoubtedly run hotter and weigh less than their present-day counterparts, and will depend on advanced materials. Metal-matrix composites (MMCs) typically consisting of a titanium alloy matrix and ceramic reinforcement, are generally held as leading candidates because they are light and maintain their strength at higher operating temperatures.
