Outline
  • Rockets and Their History
  • Aerodynamic Forces
  • How We Designed the Rockets
  • Our Expectations
what is a rocket
What is a rocket?
  • A rocket is a device driven forward by a force that escapes from a rear vent
  • Have many different purposes: fireworks, going into space, missiles, and just for fun!
history of rockets
History of Rockets
  • First Rockets
    • Early 1200s
    • Used by Chinese against Mongols
    • Brought to West by Mongols
  • 1600-1900
    • Newton’s 3rd Law: “Every action has equal and opposite reaction
  • Modern Rocketry:
    • Age of space travel and human exploration
    • Rockets also were now used heavily for warfare
aerodynamic forces
Aerodynamic Forces
  • There are four aerodynamic forces that our rockets will encounter:
  • These act through the center of pressure
weight
Weight
  • Is the mass of an object relative to the amount of gravity acting upon it
thrust
Thrust
  • Thrust is the force which moves the rocket through the air, and through space
  • In our case we are using air to provide our thrust
  • Is also the force which balances out the object’s weight
slide8
Lift
  • Lift is a side force that is used to stabilize and control the direction of the rocket’s flight
  • Is usually much lower than the amount of drag on a rocket
slide9
Drag
  • Drag is the resistance to the object while it’s moving
problems
Problems
  • Our group needed to design two rockets using:
    • Paper
    • Balsa Wood
    • Glue
  • One needed to achieve a high altitude
  • The other needed to achieve a long range
construction of rockets
Construction of Rockets
  • We used a NASA rocket simulator to come up with the best dimensions for our rocket
final dimensions
Final Dimensions
  • Based on the simulator we came up with these dimensions
  • Altitude
    • Nose: Length is 2.5 in., Diameter is 1 in.
    • Body: Length is 11 in., Width is 1 in.
    • Fins: 3, Length is 2.5 in., Width is 1.5 in.
  • Range
    • Nose: Length is 3 in., Diameter is 1 in.
    • Body: Length is 11 in., Width is 1 in.
    • Fins: 3, Length is 2 in., Width is 1 in.

Expectations

Range

Altitude

We expect our altitude rocket to fly 140 ft. We expect our range rocket to fly 235 ft.
