Think you have loud neighbors?

All that typing, Wow.

Do you really understand what the turbine compressor case functions as?
Tell us what the PCD is on that engine then you might understand.

I could probably discuss your non educated opinion but I don’t like to type that much.

Of more concern is that there is no shielding around the compressor section in a residential neighborhood, and no backstop behind the exhaust. Even if it is idling, conceivably something could be thrown out axially or radially.

I love it but in a residential neighborhood, this is sketch as fuck.

Doesn't matter for a baby engine like that. Even if it ruptures stuff won't go too far.

i make the same assumption you do: The guy has some experience. But experience to get it started and experience to properly do things are two different things, as we know. I assume he has experience enough to operate the machine properly.

The rest of your post is this rather meaningless.

Aircraft stuff, especially jet turbines, are reliable because:
  • metallurgy
  • inspections
  • maintenance
if a dodge slant-6 has a manufacturing defect on one piston, and a chunk of it falls off and lands in the bottom of the pan, it might still run. For decades. That's because the window between the operation of the machine and it's failure point is rather large, it was designed to be that way.

A jet is the opposite. The window between what the jet operates at and what is failure is smaller, by nature. That window is maintained by more precise metal properties. This is all well-documented in jet development history.

Then there are the penalties. A slant-6 might run 4500 rpm if you held it to the floor and blew ether in it. The j44 runs 15,000 rpm according to wiki. That means the penalties are more than 3x as high as everyone here knows, it's not a linear relationship.

A rod slung out of the inside of a heavy iron casting at 4500pm is a lot less hazardous than a compressor blade flung out of a sheet-metal housing at 15,000 rpm. Energy is .5mv^2, velocity matters more, and the housing is smaller.

A steam traction engine requires a boiler inspection. I wouldn't even be around one that wasn't inspected, and there are criminal penalties for operating boilers that aren't inspected. In some cases, you can't cross state lines with vintage steam engines without getting certified.

What is the equivalent for jet turbine engines?

You are clearly very comfortable with them, and i'm not, but you're also ignoring massive differences between what this thing is and what we're normally familiar with.

Jet engines are safe and reliable because they are maintained carefully. So again, i think this is hinky as fuck.

How do i know that one blade of that machine hasn't been pitted near the root and is just waiting to shear off as soon as he throttles up? I'm not comfortable with his or your assurance otherwise unless i see objective proof that it's certified somehow, which it's not.

All that because someone made noise at 7 in the morning? God forbid someone gets up at a decent hour and goes about their day.

He's entitled to his own opinion. I've had neighbors idle 2stroke diesel semis 10 feet from my bedroom window at 3am forever and constantly have Harley fags drive past my place with more wrist twist than common sense at all hours of the night...especially the retards that "upgrade" to straight pipes. If you want to race, quietly walk up to the door and let me know if I'm riding the ancient Duc that will still smoke you, the recent ICC that will def smoke you, or the modern shifterkart unlimited that will make you look like a fool, and where we wont piss people off. If I end up in jail for punching a jackass for being a jackass, I expect others to act in a way undeserving of me punching them in the face repeatedly. Courtesy is underappreciated in our society.

What does any of that have to do with landscapers working at normal hours?
