With a propeller.
If your car makes a squealing sound when you are turning it is because your brakes have worn out. When the brakes wear down below a certain point, a wire pops loose. That makes a squeaking sound.
A propeller is connected to a drive shaft which is connected to an engine that runs the same way as a car
It's the engine that makes the propeller go fast, not the number of blades.

An engine driving a propeller or a turbine causes thrust.
My question is: What sound does a lion make ? Roar.
The pitch of the propeller causes this noise.
they make powerful propeller sounds.
A propeller typically produces a combination of aerodynamic noise and mechanical noise. Aerodynamic noise arises from the airflow over the blades, leading to a characteristic whooshing or rushing sound. Additionally, mechanical noise can result from vibrations and interactions between the propeller and the engine or the surrounding environment. The overall sound can vary based on the propeller's design, speed, and operating conditions.
Sounds like a belt or belt tensioner needs to be replaced
You should check the struts.
