ROCKET PRINCIPLES

This presentation will give a brief description of rocket principles.

ROCKET PRINCIPLES

Newton’s First Law:Objects at rest will stay at rest or objectsin motion traveling in a straight line willstay in a straight line unless acted upon by an unbalanced force.

ROCKET PRINCIPLES

Newton’s Second Law:Force is equal to mass times acceleration.

F = MA

ROCKET PRINCIPLES

Newton’s Third Law:Every action has an equal andopposite reaction.

ROCKET PRINCIPLES An unbalanced force must be exerted for a rocket to lift.-1st Law

The amount of thrust will be determined by the mass of rocket propellant burned. – 2nd Law

The motion of the rocket is opposite to the thrust from the engine. – 3rd Law

PROPULSION SYSTEMS

There are two basic types:

•Solid Rockets

•Liquid Rockets

PROPELLANT

A propellant is a mixture of fuel

and oxidizer. It is what allows a

rocket to fly in space.

THRUST•The "strength" of a rocket engine is called its thrust.

•Thrust is measured in "pounds of thrust" in the U.S. and in Newtons under the metric system •4.45 Newtons of thrust equals 1 pound of thrust.
