How do the propellers on a plane help the plane to fly?

Answer 1

It can spin either way.

The way in which it spins determines the direction it pulls the object it is attached to.

if it the propeller spins clockwise it pushes air backwards causing forward thrust, and if the propeller spins anti-clockwise it pushes air forward creating reverse thrust.

.

additional The above applies to an individual prop. However, for example, Spitfire aeroplanes were made with both clockwise and counterclockwise rotating props.

Which is by and large OK, but just as you leave the ground, the prop exerts some torque on the plane body, and this is countered by the application of other control surfaces. Such as flaps and rudder.

But before you apply the corrective measure, you better be sure you are doing it the right way. This problem has caused accidents.

Answer 2

They make the plane move forward. The plane has to be moving forward for the wings to keep it in the air.if the propellers were in a diffrent locatin the plane will move backwords for more information go to ask.com. ------------------------------------------------------------ The propellers provide thrust which in turn keeps the plane moving forward and created lift for the aircraft. Although the propeller's position matters, there are several propeller configurations. Ex. Push prop/push/pull etc

Answer 3

propoller gives thrust to fluid by imparting linear momentum .
