Aileron
Roll
Answers
- Cut 0.25
inch ( 6 mm) slits about 1 inch (2.5 cm) from the end of each wing and
then fold these areas down. The tabs you have just made are called:
ailerons
- Looking at your
paper airplane from the front, fold the right tab down and the left
tab up so that it resembles the diagram on the Aileron Roll Web page.What
motion do you predict will result when you fly your airplane? roll
left - counterclockwise
- Fly your paper
airplane. Was the motion the same as your prediction in the question
above? If not, describe how it differed.Answers will vary. Answers
will vary.
- The paper airplane
should have rolled 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? Answers will vary.
- Now bend the left
tab flat and bend the right flap up. Predict the motion you will see
when you fly the paper airplane: roll right
- clockwise
- Fly the plane again.
Was your prediction correct? If not, describe how it differed. Answers
will vary.
- If the tab is bent down,
is more lift or less lift generated by the wing? more lift
- Bend the tabs on
both wings up and fly your paper airplane. Explain what happened. Answers
will vary.
- In what situation
would a pilot want to use the ailerons to roll the plane?
One
wing dips lower than the other.
- Where are the ailerons
located on a commercial jet? ends of wings
- If the ailerons
were used during landing to decrease lift, which way would they be deflected?
upward
- Where is a spoiler
located on a wing of an airliner? between
leading and trailing edges of wing
- If a spoiler is
deflected on the left wing of an airplane, which way would the airplane
roll as viewed from the front? left - counterclockwise
- If spoilers on
both wings were deflected the same amount at the same time, how would
the plane's position change? decrease in
altitude - would not roll
- Cut and attach
small strips of paper to your paper airplane's wings with tape. Fly
it. How did your spoilers affect the flight? Answers
will vary.
