- Go to the Foilsim
Software Program and set initial conditions as follows:
Airspeed = 100 km/h, Altitude = 5000 m, Angle = 1 deg , Thickness =
12.5, Camber = 12.5, Area = 10 sq. m.
What is the Lift?
4757 Newtons
- Change the area
as shown in the following table and record the associated lift for each
area to complete the table.

TABLE 1
- Construct a graph
of Wing Area's effect on Lift with an Independent Variable (X) of Wing
Area and a Dependent Variable (Y) of Lift. Label each axis correctly
to include units. Print out graph from
FoilSim Program.
- Interpolate the
lift for a wing area of 70 sq. m. What is the lift? 33,299
Newtons
- Extrapolate the
lift for a wing area of 100 sq. m. What is the lift? 47,575
Newtons
- What is the shape
of the curve formed by this relationship? A
line
- Write the equation
for this relationship! Y = 475.75 X where
Y = lift and X = area
- Based on the relationship
between lift and area of a wing, how would you increase the lift on
a wing? Increase the Area of the Wing!!!
