The lifespan of a jet engine can vary significantly depending on its type and usage, but commercial jet engines typically last between 20,000 to 30,000 flight hours before requiring major overhauls. Some engines are designed for longer durations, potentially exceeding 50,000 hours with proper maintenance and care. Factors such as operating conditions, maintenance practices, and engine design also play crucial roles in determining the overall lifespan. Regular inspections and maintenance are essential to ensure safety and performance throughout the engine's life.
Long Enough
If you're referring to the power of the engine, it is not in hertz. The power of of a jet engine is measured in pounds.
Well, there are many reasons but the main one is the jet engine is many times larger and more powerful.
The JT9D-7R4E jet engine typically has a lifespan of around 15,000 to 20,000 flight hours on wing, depending on operational conditions and maintenance practices. Factors such as flight frequency, engine care, and adherence to maintenance schedules can significantly influence this duration. Regular inspections and overhauls can extend its operational life.

About 48 hours.
More or less than 3 hours (depends on jet engine)
A jet is a type of engine that powers many aircraft and does not have anything to do with airplane size.
The Thunder Jet was the standard engine in the Cobra. There were 7,675 Cobras made in 1970. I cannot find a breakdown on how man came with the standard Thunder Jet engine and how many came with the Cobra Jet & Super Cobra Jet engines.
Jet engines are not calibrated as such but get routine maintainance depending on the flying hours of the engine. They also undergo major overhaul and preformance runs during their life. But i think calibrate is the wrong term.
I would estimate 21- 25 countries can and do produce jet engines
Frank Whittle was the invetor of the jet engine.
