## FoilSim

Lift Relationships

Activity

If so instructed by your teacher, print out a worksheet page for these problems

Using FoilSim, set the following parameters:

Airspeed: 100 mph

Altitude: 0 ft

Angle: 0.0 degrees

Thickness: 12.5%

Camber: 0.0

Area: 1 sq ft

1. What is the value of lift with these parameters?

2. Determine the Lift value for each of the prescribed Angle levels, while keeping the other values the same.

#### Angle

3. Graph the values for Angle and Lift. (Place the Angle on the y-axis and the Lift on the x-axis.)

4. What is the relationship between the Angle and the Lift?

5. Write an equation that will sum up this relationship.

6. Using FoilSim, and keeping the angle set at 4 degrees, determine the Lift values for the following Airspeeds.

 Airspeed Lift (lb.) 25 mph _____________________ 50 mph _____________________ 100 mph _____________________ 200 mph _____________________

7. On another graph, plot the values for Airspeed and the corresponding Lift levels.

8. What is the relationship between the Airspeed and the Lift?

9. Write an equation that will sum up this relationship.

Extra Activity:

a. Using FoilSim, manipulate the values for all the different variables until you get the highest lift value possible on this particular simulation.

b. What were your values for the different variables (be sure to include labels)?

c. What do you think will be the possible result if this lift was applied to a real plane?
