Coming to your engine – parts stronger than a speeding bullet

The actual bullet test is probably not particularly useful, but it is true that the forthcoming generation of commercial and, rather sooner, military engines is likely to feature ceramic matrix composite components (stuff like silicon carbide for example). The efficiency gains are remarkable at a time when it’s getting very difficult to squeeze more out of the basic jet engine concept without exotic design changes.

The issue has been their durability. Now General Electric (and, by extension, CFM) think they’ve cracked it. And they have a movie to illustrate the point. More info here.
