Hello, I'm doing a full stress analysis on a complete aircraft engine. so i was looking for documents with full specifications of the engine ( blueprints,charts,data tables, ...etc. ) . I know that most of these information are top secret whether it's a civil engine a military engine. However I was hoping that there would be some data out there for old engines that are out of service. I've been surfing the web searching for the past week and still no luck!. I'm looking for data on any engine (turbojet or turbofan).
