 Aileron Roll Problems If so instructed by your teacher, print out a worksheet page for these problems. Open the slide called Aileron Roll (with text). Study the labeled diagram and read the explanation of aileron roll. After you have read the Web page about Aileron Roll, make a paper airplane. Click on How to make a paper jet model (http://www.grc.nasa.gov/WWW/k-12/WindTunnel/Activities/foldairplane.html) for directions or fold an airplane of your own design. Then:  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:___________________  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? ___________________________________ Fly your paper airplane. Was the motion the same as your prediction in the question above? If not, describe how it differed. ______________________ 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? ___________________  Now bend the left tab flat and bend the right flap up. Predict the motion you will see when you fly the paper airplane: ______________________ Fly the plane again. Was your prediction correct? If not, describe how it differed. ________________________ If the tab is bent down, is more lift or less lift generated by the wing? _________________ Bend the tabs on both wings up and fly your paper airplane. Explain what happened. __________________________________________ In what situation would a pilot want to use the ailerons to roll the plane? ________________ Where are the ailerons located on a commercial jet? ________________ If the ailerons were used during landing to decrease lift, which way would they be deflected? ________________ Where is a spoiler located on a wing of an airliner? ________________ If a spoiler is deflected on the left wing of an airplane, which way would the airplane roll as viewed from the front? ________________ If spoilers on both wings were deflected the same amount at the same time, how would the plane's position change? ________________ Cut and attach small strips of paper to your paper airplane's wings with tape. Fly it. How did your spoilers affect the flight?
