That could happen with propellors that have Constant Speet Units. (Propellor pitch is able to be changed) The act is called ‘feathering’ . This can happen on multi engine aircraft and reduce the drag of the side with the failed engine. Cheaper propellors are fixed pitch and no means exist to change them. (I believe some propellor are able to have their pitch changed by a maintainer on the ground so the aircraft can be optimized for climbing, cruising or a combination of both)

‘Reverse Thrust’ is also possible in so e Other aircraft. the blade reverses to the point where it pushes the wrong way so the engines assist breaking* after landing. * Typo, but I’m leaving it in =)

Haven’t seen any memes, so could be wrong but have heard some news stories about people in the United States government wanting to rename the Gulf of Mexico to the Gulf of America.

Not exactly a scientist, and I agree with the other long answer about blades disrupting each other, so I’m replying to see if I can help you visualize/understand some of the forces at play.

My source is a Tom Clancy book about a sub war.

Typically the subs are stealthy, however if I remember correctly, I’d they decided to gun the engines (think something like 105% on the reactor), they could spin the blades really fast.

But compressing the water as the blade spins makes some of it high pressure and the other side of the blade low pressure.

This would reduce the pressure low enough that the water would become a gas and in doing so, make a lot of noise and was called cavitation.

When the sub commander did this, it did mean the ship could go very fast, but was noisy as hell and anyone near would know they were around, but if someone shot a torpedo at you and you had to get out of range…

Before readying the other reply I thought something like this might have happened and disrupted the smooth laminar airflow.

I know aircraft have over speed and under speed warnings for propellors too, but I thought that was more to do with not breaking them than 'grabbing the air ’ efficiently. Supersonic propellor tips aren’t a good idea.

I remember seeing a mobile phone cable section in a servo there were one cable had 3 heads that could be changed as needed. Dunno about whether they also do data though. So buying a combo cable could be a solution.

I haven’t had any detailed experience or suggestions, but if your considering anything, what about backup features.

Some sort of automatic remote realtime backup might be useful to some people.
