comparing russian and US jet engines OH times

Interesting, since the USN decommissioned all of its afloat IMA s and most
(if not all) of its shore based IMA s. This despite the fact that the vast
majority of ships now have "aircraft" engines, the LM2500 and derivatives.

Suspect that the operating cycle for ships is about the same as for airliners
or even transcontinental pipeline pump power units that alsu use variations of
aircraft turbine engines. They tend to run forever since they are started and
run at the same power setting all the time. When they accumulate enough time
or on-condition mauintenance analysis indicates they are losing efficiency
(increased fuel flow and increasing temps in the hot section) they are pulled
and sent to depot. The maintenance concept is usually driven by usage.
Fighters tend to use up life in their engines far quicker than any other
application and require more maintenance. Most of what I have offered has more
to do with fighter engines than anything else since the originator of the
thread mentioned the Su-30.
