- Rockets and Their History
- Aerodynamic Forces
- How We Designed the Rockets
- Our Expectations

- 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!

- 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

- There are four aerodynamic forces that our rockets will encounter:
- These act through the center of pressure

- Is the mass of an object relative to the amount of gravity acting upon it

- 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 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 is the resistance to the object while it’s moving

- 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

- We used a NASA rocket simulator to come up with the best dimensions for our rocket

- 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.

Range

Altitude

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