Know All the Wright Angles
Activity Sheet #2
| Directions: |
Use the graph below to help the AIAA pilots answer their questions.
This is a graph showing the data collected on the Flyer replica. It
displays the lift and the drag at different angles of attack when
the Flyer for different runs. |
- On the graph above, circle the point at which the most lift is being
generated.
- How many pounds of lift are being generated? _______________
- What is the angle of attack? ______________
- On the graph above, draw a box around the point at which the most
drag is being generated.
- How many pounds of drag are being generated? _____________
- What is the angle of attack? _____________
- Give the angle of attack at which 800 pounds of lift are being generated.
- At which angle of attack does drag begin to steadily increase?
- Contrast the increase in lift to the increase in drag.
- What do you think is your answer to question #5 has to do with the
Flyer's lift capability?
- A good cruise angle is one in which the design has the greatest difference
between lift and drag. Doing some subtraction, calculate which angle
of attack would most likely be the most efficient cruise angle? (Hint:
you don't have to subtract the drag from lift of each angle of attack.
Narrow the field, by looking for the biggest gap between lift and drag
and then doing some subtraction.)
- If lift and drag continued to increase at the same rate, predict the
lift and drag in pounds and place 2 "x's" on the graph at each point.
