A "hot start" is where you give the turbine engine too much fuel too
soon during the start up or there is fuel left in the engine after the
previous shutdown. The power turbine wheel over heats. If the EGT
temperature goes past read line then the turbine wheel and other
expensive parts MUST be replaced or sometime in the not too distant
future the turbine wheel will come apart rapidly. If the hot start is
bad enough and exceeds red line it can cost $50K- $1M+ for the engine
tear down and parts replacement.

Thanks for the incoming comments. We need to stop this guy before
people start dying again. Stitt's turbine startup sequence is WAY
wrong. His method will cost you $$$$$ in turbines , as his method
guarantees hot starts, or a least unnecessary high temps.

Student, and a beginner here...still learning about pistons, but
I've seen this term before here...Please explain 'hot starts'.


Thanks.
