The speed of the propeller and the size of the propeller
The airplane propeller rotates at high speed under the engine, resulting in pulling force and pulling the plane forward. It's people's common sense. However, some people think that the pull of the propeller is due to the propeller rotating when the blade in front of the air suction and back to the rear, with the reaction of air force to pull the plane forward flight, this understanding is wrong.
So, how does an airplane propeller generate a pull? If you look carefully, will see the aircraft propeller structure is very special, but with a single blade slender wing blade twist angle, blade twist angle (blade angle) is equivalent to the wing angle of attack, but as the blade tip and blade angle rotation plane is parallel to the blade root gradually changing twist angle.
