Rudder - Yaw Worksheet
After you have read the Web page about Rudder -Yaw, make a
styrofoam airplane. Click on McEagle
Styrofoam Glider
(http://www.grc.nasa.gov/WWW/K-12/TRC/Aeronautics/GLIDER.html) for
directions.
- Cut two 0.25 inch (6 mm) slits about 1 inch (2.5 cm) apart
from each other on the vertical stabilizer of your styrofoam
glider and then bend this area to the right and then left to
crease it. The tab you have just made is called the
____________________.
- Looking at your styrofoam glider from the front, fold the tab
to the right so that it resembles the diagram on the Rudder - Yaw
Web page.What motion do you predict will result when you fly your
airplane? ___________________________________
- Fly your styrofoam glider. Was the motion the same as your
prediction in the question above? ________ If not, describe how it
differed. ____________________________________.
- The styrofoam glider should have yawed counterclockwise around
its center of gravity if viewed from the front. Where is its
center of gravity in terms of the length of the airplane?
____________________
- Now bend the tab left. Predict the motion you will see when
you fly the styrofoam glider:
________________________________________________________________.
- Fly the styrofoam glider again. Was your prediction correct?
___________ If not, describe how it differed.
________________________
- When the tab is deflected to the left, where is more force
generated? ________________
- When would a pilot use the rudder to cause an airplane to yaw?
