I am fascinated by the technology of jet engines. As a hobby, I might like to create a detailed animated 3D model of one (and publish it with a Creative Commons license). Obviously I am not going to find any actual detailed technical drawings of recent or current in-production engines. They are trade secrets or even military secrets. But models from the 50s or early 60s might be a different story. Looking for suggestions for a model for which ample documentation is available, for free or for a reasonable price. It is not important as such whether it is a British, American, or French or other continental European design.
(I am at the moment building an add-on for Microsoft Flight Simulator of the English Electric Lightning that uses the Rolls-Royce Avon Mk 302, and have not been able to find any detailed information about that late Avon model. Some documentation for earlier Avon models yes, but not very detailed drawings. So the Avon is not the answer. Anyway, for that purpose I don't need to model the engine in great detail. It would just be nice to at least get the dimensions and number of compressor and turbine blades and stator vanes correct, if I bother modelling those.)
Perhaps even some Soviet one (with ideas "borrowed" from a Western model)? One might imagine that when the USSR collapsed, lots of military-related technical manuals and drawings ended up for sale to enthusiasts. I don't know Russian but drawings with measurements would be useful anyway.
