Arash,
I have worked for both Rolls-Royce and GE; I currently run the IVHM (same as EHM) Centre at Cranfield University in the UK. I’d be glad to answer questions but it would probably be better to get answers directly. For Rolls-Royce you should contact Rich Adams ([email protected]), for Pratt&Whitney Dr Ravi Rajamani ([email protected]) and for GE I think its Ed Hindle but I don’t have his email. Also the SAE E32 committee is set up to deal with health management issues and would be able to help with your line of questions. The incoming chariman is Duncan Chase from Rolls-Royce ([email protected]). Let me know if you need anything else.
Cheers,
Ian
