The propellor basically propels the aircraft. without it the airplane wouldn't go anywhere.
It propels.
Thrust
A jet engine usually propels an airplane. The jet engine propels the plane by ejecting extremely hot gasses out the back of the engines. Another way is by using huge fans to suck in air and blow it out the back.

The curved shape of the propeller deflects airflow to it's rear. This is 'thrust' that propels an aircraft.
An airplane is propelled forward by its engines, which generate thrust by expelling high-speed exhaust gases. The thrust generated by the engines overcomes drag forces on the airplane, allowing it to move forward.
