FoilSim

Lift Relationships Worksheet


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 at the original parameters? ___________

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

Angle
Lift (lb.)
0 degrees
_______________
2 degrees
_______________
4 degrees
_______________
8 degrees
_______________
16 degrees
________________

3. On the graph below, 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 angle and lift? ___________________________

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

6. Using FoilSim, and keping 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
