Step 1.
In FoilSim, choose Metric Units. Set the
following input conditions:
Airspeed = 0 km/hr
Altitude = 0 meters
Angle = 0 degrees
Thickness = 12.5 %
Camber = 5.0 %
Area = 10 sq. meters
Step 2.
Using the chart below, record the Airspeed and the
Lift. By changing the Airspeed, make at least 9
additional readings. Record these in the chart.
Airspeed
(km/hr)

Lift
(newtons)

0




















Step 3.
Enter your data into the Lists in your calculator. Set
up Stat Plot so that the Airspeed is your
independent variable and the Lift is the dependent
variable. Graph the data on your calculator and make a sketch on
the graph found in the worksheet.
Step 4.
In FoilSim, push the Plots output button and select Lift
vs. Speed. How does this graph compare to yours?
Step 5.
Which kind of function does this graph represent?
Step 6.
Using the regression
equations (http://www.ti.com/calc/docs/act/pdf/marcus09.pdf)
from your calculator, determine the equation of best fit.
a = ___________________
b= ___________________
c= ___________________
R^{2} = ___________________
equation: _______________________________
Step 7.
What does this equation tell you about the relationship between
the change in Lift and the change in Airspeed?
Step 8.
Using the graph and/or the equation, what would you predict the
lift to be given an airspeed of 300 km/hr.?
