Why does NG (N1) limiting occur in turbine engines?

NettetOverspeed is a condition in which an engine is allowed or forced to turn beyond its design limit. The consequences of running an engine too fast vary by engine type and model and depend upon several factors, the most important of which are the duration of the overspeed and the speed attained.

NettetThis happens well before the engines reach their temperature limit, and before transmissions reach their structural limit. The only other limit that I would imagine we are hitting is something with either the N1 trying to overspeed to better compress the air, or the air just can't be further compressed with our engine, regardless of the speed. Nettet11. jul. 2024 · An over speed trip is a safety feature provided on the diesel engine of the ship to restrict uncontrolled acceleration of the engine, leading to mechanical failure or untoward accidents. In order to prevent the speed of a diesel engine to go beyond the pre-set speed range, an over speed trip is used in the diesel engines.
