Wind Gauges

Assessment of Knowledge Gained Using
FoilSim Interactive Simulation Software

Subject Area: Physical Science and Mathematics

Grade Level: 8-10

National Standards:

• Mathematics:
  • Use and value the connections between mathematics and other disciplines.
  • Unify concepts and processes through the production of models and explanations.
• Science as Inquiry: Understandings about scientific inquiry.
• Physical Science: Motions and forces.
• Science and Technology:
  • Abilities of technological design.
  • Understandings about science and technology.

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 determines the airflow around various shapes of airfoils. As you change the parameters of 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 NASA Glenn Research Center to illustrate an example of their research.

Macintosh or MS-Windows 3.x, 95, or NT versions of FoilSim are available for downloading off the World Wide Web at FoilSim Download.

Shown below is a screen shot from the program showing the 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.
