Introduction-intro to the project

Statement of purpose, and how I’ll experiment

I did this experiment because energy from reusable natural resources is becoming more of an issue, and sailing is transportation, using reusable natural resources. I wondered if a changing sail depth or camber would effect how well the wing went upwind. I decided to make 6 wings; each wing had a different camber. The smallest camber being 1.5 cm and the biggest 4 cm, so each wing had a .5 cm deeper camber than the last. They were tested in a small wind tunnel, all at the same angle of attack.

Hypothesis, and variables

My hypothesis was that if each wing was tested at the same angle of attack the only thing differing between would be their camber, then the wing with the smallest camber would prove to be the most effective. The independent variable, or what was changed, in this experiment was the camber of the wing tested. The dependant, what was measured, was the amount that the wing lifted.
