Outline

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

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

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

Expectations

Range

Altitude

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