A quick look at RollsRoyce (RR:LSE)/RYCEF

[earthtodan]

An interesting alternative in my opinion is Safran (SAFRY), a French company that is totally exposed to aerospace. They have a longstanding joint venture with GE to build jet engines, so more of a pure play on GE Aviation. Not sure if you're interested in the aviation or power generation side of RR though. Confero on Seeking Alpha has written some good articles on this industry.
