3. Understand
The purpose is trying to get one or two models to fly the longest, and stay in the air the longest.
Materials:
Paper
Paper clips
Big paper
Tape (Scotch or clear tape)
Scissors
Weights
Books
Staples
You can use anything that doesn’t modify the material or create thrust or propulsion.
The solution is increasing, as it allows greater distance. The brainstorming process is about understanding Lift, Thrust, Drag, and Gravity on a craft which makes advantages and disadvantages by themselves.

4. Explore Ideas we explored: More surface area on the wing
More weight for better propulsion
Design Book that improves the design and basis
Heavy in the front to have momentum
Adding weight to get momentum for flight
Longer flying time equals to longer distance
Less surface area has less drag on the craft
Modify the design of dart aircraft to have larger surface area
Added flaps to help flight time in the air

5. Define These ideas translated to design changes:
Short but make the wings bigger, then you get a great guide and speed of the aircraft.
Bigger wings made a great distance compared the short wing design
Hold the wings in so it doesn’t come undone in the end
Wings folded up can improve distance, glide, and speed
When the big winged craft flips, the air time is perfect

6. Ideate
We used large wings for the first model with a heavy paper nose, then we added a hexagonal triangle shape to improve distance and time in the air.
Heavy nose with a semi-small wings will make a great glider/ dart design.
A trapezoid design will help air lift with the heavy nose design.

8. Refine
We moved up to large scale for refinement, to 2 different thicknesses. We found that x2 thickness, though less stable, is best.
We modified the designs to have larger wings on the Hammer, but smaller wings on the Glider.
We removed the weight to be more stable in the back so there is more forward momentum.
Removed modifications that made the crafts fly different, mostly folds, flaps, and paper clips.
Added tape to the Hammer’s wings so it doesn’t unfold during flight.

9. Solution
We tried our design in theory in tests, those tests were huge improvements in the prototypes. The problems were the tests themselves; we used them so many times that there were dents and bruises that affected the crafts in the real tests. We were afraid this would prevent our success, but our designs prove to be workable, and some unorthodox flying helped boost our numbers.

Note: an unofficial test of the Glider afterwards got a air time of 4.4 seconds due to a change in throwing method
