Your theory that large capacity turbo compound engines increase there o/h from military to cilivan is in correct.
I have stated before this. The r985 for example had a 300 o/h life in the milTary. We had an o/h life of 1700 hours tbo with our engines. We never had one engine failure nor one cylinder failure nor one engine that never made tbo. We never ran lop.
Military have one thing over cilvil use. That is they have unlimited funds. This still is evident today.
To say they made extra hours because they ran lop is completely false and misleading.
We ran over 30000 hours with our engines.
Stop being a sheep. Go look up original P&W o/h times. Btw when they had a problem during the war the engine was removed and sent back to the USA they didn't fix very much at all.
