Lompaseo:
Commenting on shortening the lives of turbine blades.
This is a long term business consideration in decision making and not a short term concern to salvaging your current customer base
To put it another way, the operators already make decisions like this on a real time basis everyday.
Perhaps we can revisit this months from now.
It's not a "long term issue" at all. If blade life is severely compromised, for example the DC* blades went from 1000 hours to 100 hours, you are going to get 4000++ hot section overhauls all arriving at once instead of over a period of years.
There is simply not the manufacturing capacity in the world to make the blades and vanes, let alone the maintenance capacity, if a significant chunk of the worlds aircraft population gets their engines compromised. We carry the minimum of spares these days. There is no magic warehouse full of spare engines, let alone sets of blades and vanes.
You can produce a very short term fix today if you run your engines in dirty air, but you are creating a monumental problem in the following months and years if they are damaged...
