A propeller vehicle uses air resistance to generate forward thrust. As the propeller spins, it creates a pressure difference between the front and back of the propeller, causing the vehicle to move forward. The air resistance acts against the motion of the propeller, helping to propel the vehicle forward.

How do you build a propeller
Propeller airliners use Turboprops. Jets use turbofans and turbojets.
A propeller airplane is, simply put, any airplane which uses a propeller for propulsion.
The forward motion of the ship through the water, is provided by the propellor.
