Hello,

I am working on a capstone/thesis project on the Civil Aviation sector and the competitive forces in this space.

I understand that all jet engine manufacturer are now using Equipment Health Monitoring (EHM) technology and models to enhanced their Maintenance, Repair and Overhaul (MRO) of the engines.

I would like to know if any one has had any experience or knowledge about how the jet engine OEM’s (GE, Pratt & Whitney, & Rolls Royce) are using EHM in more details.

Hello,

I am working on a capstone/thesis project on the Civil Aviation sector and the competitive forces in this space.

I understand that all jet engine manufacturer are now using Equipment Health Monitoring (EHM) technology and models to enhanced their Maintenance, Repair and Overhaul (MRO) of the engines.

I would like to know if any one has had any experience or knowledge about how the jet engine OEM’s (GE, Pratt & Whitney, & Rolls Royce) are using EHM in more details.

In particular, is there any difference in terms of the level of MRO service that three OEM’s provide to their customers? For instance any difference in terms of:
a. preventive or real-time maintenance that each OEM provides?
b. how well each OEM analyzes real-time engine data and forecast MRO needs?

Also, how are these models developed? Do they use engineering rules (if the temperature of the exhaust is above certain degrees AND vibration of this part is at x level, then check part C) or other ways?

If they use certain rules, how are these rules derived?

I’d appreciate your insights.
