Week0 Preferences
Airplane Float
 * Design a rubber band powered airplane to compete in a competition
 * Goal is to have the airplane stay in the air the longest
 * Make the airplane as light as possible while still functional

Week1 Narrative
My task: work on wing design and optimal air foil

Design Ideas

- V-shaped plane

- 90 degree angle wing

- 45 degree angle plane

Week2 Narrative
My task: Experiment with small, quick models of airplanes

Materials Used

- Thin Computer Paper

- Tape

- Wooden Skewers(about 12in skewers)

Observations

- Elmers brand school glue is not very effective

- Stability of aircraft is key, wings can't be too heavy

- Making sure the frame of the wings is sealed well is important

Next Steps

- Decide on a final design

- Decide on materials to use

- Do more testing

Week3 Narrative
My Task

- Create simple model airplanes with: flat wing, 90 degree angle winglets on end, t-shaped back wing, and a propellor

Testing - After construction, the plane ran decently, posting times of 5, 12, 15, 8, and 10 seconds

- Ideally the plane could run for 30 second, but this was a good start and learning experience

Next Steps

- Come together on a final design with team

- Decide on/ gather materials

- Build the plane

Week4 Narrative
My Task

- Learn more about how wings generate lift, develop an optimal wing shape and size

Findings

- The air over the top of the wing must go faster than the air beneath the wing. This will cause pressure downward, which causes lift upwards.

- When a wing that is flat takes on wind head-on, it naturally tilts downward by about 2 degrees.

- The competitors in the competition use planes with a wingspan of around 35 centimeters, and recommend a tilt of the wing between 15 degrees to 30 degrees

Next Steps

- Report Findings to teammates

- Come together on a final design with team

- Decide on/ gather materials

- Build the plane
