Fun fact true in most helicopter turbine engines. “About 70% of total engine power is dedicated to spinning the compressor section and engine driven accessories in an engine.
So if you are pulling 100% Q that equals 500 Hp on a turbine engine to drive your rotor system the total horsepower being generated inside that engine is +- 1667 Hp.
See I did remember a little from my 250 course all those years ago.
No….high TOT / EGT / T4 is not the result of “Flying too close to the sun”! (Actual answer on the course by a fellow having a major helmet fire during one early morning verbal quiz and upon having drawn a complete mental blank as to possible causes of abnormally high TOT and just went for giggles. It took 5 minutes before the instructor and class got themselves back to order. Especially humorous because he was a real smart fellow and a very switched on dude.)
