Firing up the engines

摘要

Rolls-royce is to develop new materials to allow its aircraft engines to operate at much higher temperatures, significantly reducing carbon dioxide emissions. The £3.7m Materials for Arduous Cycle and Emissions (MACE) project will develop materials that are suitable for use in advanced-cycle engine designs, with higher operating temperatures and more efficient compressors. Such engines will help meet the goal set by the Advisory Council for Aerospace Research in Europe to reduce CO_2 emissions per passenger km by 20 per cent by 2020.
