  • Problem-Solving and Decision-Making Tools - Routinely and efficiently use on-line information resources to meet needs for collaboration, research, publications, communications, and productivity.

Objectives:

You will use FoilSim interactive software to become familiar with the way in which the flow of air across or around an airfoil affects its ability to create lift.


FoilSim is an interactive simulation software package that examines the airflow around various shapes of airfoils. As you change parameters such as airspeed, altitude, angle of attack, thickness and curvature of the airfoil, and size of the wing area, the software calculates the lift. The package was created at the NASA Glenn Research Center.

FoilSim II is a Java applet program that executes inside the browser of your computer. It is available on the World Wide Web at http://www.grc.nasa.gov/WWW/K-12/airplane/foil2.html. You can also download the program to run off-line.

Shown below is a screen shot from the program's controls and displays. You may change the values of the variables by using the slider or the input box on the left of the slider.

To use the slider:

  1. Click the mouse pointer on the arrows at the ends of the slider.
  2. Click the mouse pointer anywhere between the slider and the arrow.
  3. Drag the slider with the mouse.

To use the input box:

Simply select the value in the input box, key in the new value, and press Enter or Tab when finished. The button on the slider will move corresponding to the value typed in the box.

To begin the problem, click on Wind Gauge Activity.


Assessment:

You, or you and your partner(s), will be evaluated on the ability of your wind gauge to determine the speed of the wind.

Evaluation:

You will be able to use FoilSim to complete the activity and develop strategies that will solve the concept of wind speed. The model should demonstrate a knowledge of the factors that affect lift.
