What is the meaning of propulsion?

Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.

What are the four main types of propulsion systems?

We will discuss four principal propulsion systems: the propeller, the turbine (or jet) engine, the ramjet, and the rocket. Why are there different types of engines? If we think about Newton's first law of motion, we realize that an airplane propulsion system must serve two purposes.

What is the purpose of an airplane propulsion system?

If we think about Newton's first law of motion, we realize that an airplane propulsion system must serve two purposes. First, the thrust from the propulsion system must balance the drag of the airplane when the airplane is cruising.

What is the root word of propel?

borrowed from Medieval Latin pr?pulsi?n-, pr?pulsi? "action of driving out or urging on," derivative, with the suffix of verbal action -ti?n-, -ti?, of Latin propellere "to push or thrust forward, compel to go onward" (with -s- from past participle and verbal noun pr?pulsus) — more at propel “Propulsion.”
