Basic Principle of Jet Engine Operation
• Newton’s Third Law of Motion: For every action there is an equal but opposite reaction.
PushMoves In this Direction

Are We Really Pushing in An Opposite Direction?
• The answer is yes when you consider that to push to the right you must also be pushing to the left, otherwise you would move in that direction.

Jet Engines Are Really Reactive Engines
• “JET” is really a slang term for Reactive Engines that use thrust as a propelling force.
• Reactive Engines are engines that move forward because of a rearward discharge of thrust.

The Term “Jet Propulsion”
• Jet Propulsion is a propelling force (thrust) generated in the direction opposite to the flow of a mass of air, liquid or a gas escaping at a high velocity through an opening called a nozzle.

Summary:
• Instructional Objectives:• 1. What is “Jet
Propulsion?”• 2. Why is Newton's Third
Law so critical for jet engines?
• 3. Give 4 examples that use a reactive engine.
