How long did they operate for? As I understand it the J34s on the Neptunes
only operated for a short duration each flight, correct mje if I am wrong.
Also how did the turbine blades look at overhaul? Were the fuel controls OK
or did they need to have numerous internal parts replaced due to the poor
lubricating qualities of gas? I admit I got my info from a former P2V crew
chief I used to work with. The big question is how many running hours (as
opposed to hanging under the wing hours) did the Navy get? A modern jet
should get 6000 + hours as a minimum and are usually limited by cycles on
the internal parts. The record for a commercial jet engine is upward of
24,000 hrs. My carrier had an RB211-524B4I do 24,000+ and held the record
for a while, but I heard that was broken a little later by another carrier.
I don't recall what engine type or carrier.

As far as using gasoline, especially avgas, is concerned this is
a different matter. The engine will probably run....but not well,
or for very long. The combustion chambers and the turbine blades
and vanes will lead up dramatically in a short period of time.

As I posted earlier, the Westinghouse J-34-WE-36 jet engines
installed on the Lockheed P-2V Neptune were operated exclusively
on 115/145 AVGAS. I flew them for three years and never had
a problem. Always obtained 100% RPM for takeoff.
Tell us your "real world" experience with operating jet engines
on AVGAS, generalities just don't work.
