Work?

2005
Basic Principle of
a Rocket
• “Every action has an equal and opposite
reaction.”
Model Rockets
•Type that you’d
blast off in large
backyard or field
•Engine rated by power
•Engine ratings are in
letters
•Letters g and above are
high powered model
rockets
Model Rockets
•In engine the fuel turns into
propellant
•propellant is what makes rocket
shoot up in air
Space Shuttles
• Fuel burned with oxidizer or propellant .
• Creates hot gasses.
• Shoots rocket up.
Space Shuttles
• Shoots up because of hot gases.
• Pushes through throat because of pressure and
compression.
Space Shuttles
• Upward force
becomes greater than
downward force
•Lifts off because of
Newton’s third law
Navigation of Space Shuttles
•Uses a GPS.
•Sends all information like position in space, its
velocity and its attitude to flight computers.
•To know which way it is pointing, has several
gyroscopes.
•The computers
then control the
navigation from
there unless on
manual
navigation.
What the Computers
Control
•Operations of the
orbiter.
•Interfacing with the
crew of the shuttle.
•Caution and warning
systems.
•Data acquisition and
processing from
experiments.
•Navigation.
Solid-Fuel Rockets
•Used to be used to deliver bombs
•Need something to burn quickly but not explode
•Fuel similar to gunpowder with altered
ingredients
Liquid-Propellant Rocket
•To fly needs fuel and oxidizer
•Pumped in combustion chamber
•Many different combinations of fuel can be
used
