Wing Area Effects Activity


If so instructed by your teacher, print out a worksheet
page for these problems.
To answer the
questions in this activity you will need to launch the application
FoilSim.
Also open the slide called Size Effects
(with text) and read the explanation on how size affects lift.
 Open FoilSim 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? ____________
 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.
 Interpolate the
lift for a wing area of 70 sq. m.
What is the lift?
_________________
 Extrapolate the
lift for a wing area of 100 sq. m.
What is the lift?
_________________
 What is the shape
of the curve formed by this relationship? _________________
 Write the equation
for this relationship.
 Based on the relationship
between lift and area of a wing, how would you increase the lift on
a wing?
