What

Propulsion of Aircraft is an aircraft engine that generates a thrust, which is typically a propeller or a propulsive nozzle. These engines produce balance to drag of the airplane when the airplane is cruising and to exceed the drag of the airplane for the airplane to accelerate. How well do you understand the Propulsion of Aircraft? Find out by taking this quiz.
