There are no bolts holding the fan or turbine blades on the rotors.
I know that.
Sorry for the short answer but my wife is painting and just handed me a wet roller to clean. I think she has a brush coming my way soon.
I was just pointing out that the Chinese counterfeit baby food, dog food and aircraft parts. The guy that got caught making the bad baby food was executed.
I think we got some counterfeit injection nozzles for the 58000hp Sulzer diesel on my ship once. The whole box of very expensive nozzles failed. And the ship’s engine had to be shut down at sea to replace them. And then those failed. We limped home on dead cylinders.
I have held steam turbine blades in my hand. Very impressive engineering.
