As every pilot and mechanic knows, high temperatures are the bane of any engine. But as engineers strive to design smaller, more powerful turbine engines by adding compressor stages, the compression ratio goes up and so does the temperature of the ram air. At a compression ratio of about 20 to 25, ram-air cooling becomes inefficient. The solution, researchers believe, lies with cooling the air before it goes into the combustor.
