The pitch concept is not exclusive for propellers, other mechanical devices like screws also use it. Prop Makers use a wide variety of materials, techniques and tools, to design and create the required props. But at the exit, the velocity is greater than free stream because the propeller does work on the airflow. They produce lift with the vector facing forward and we choose to call it thrust. Whirligig propeller hubs have to be wide enough to hold the propellers in place perpendicular to the shaft. The rotation of the propeller forces air down toward the ground.

The performance of a propeller suffers when transonic flow first appears on the tips of the blades. A diesel submarine is a very good example of a hybrid vehicle. It is also used in some motor boats.
