 * DETERMINING THE AMOUNT OF LIFT IT TAKES TO LIFT A HUMAN **


 * ABSTRACT **

The purpose of this experiment was to determine which wing design would lift a human and how big the wing area would have to be. The hypothesis of this experiment was that the first wing design, curved on top and flat on the bottom, will provide the most lift out of the three wing designs. All three wing designs were tested on an electric balance while the fan blew over and under it. The fan was set to the highest setting. The numbers on the balance were negative instead of positive like a normal mass would be. The numbers being negative meant they were pure lift. All the numbers registered on the scale were pure lift. The trials were averaged and put into tables and then into graphs. It was found that the second wing design generated the most lift. It generated a lot more lift than the first wing designs and more lift than the propeller.

To improve this experiment a fourth design could be added. It could be a complete arch. The second wing design could be tested again. The actual plane could be built and flown. A model plane could be made and tested as a pre-experiment to the actual plane.
