Aeronautics - Fluid Dynamics - Level 3


Simulator Aifoil ImageBasic Aerodynamics Software is educational software designed at the NASA Lewis Research Center to instruct students in the basics of aerodynamics. The software contains two main parts, a baseball pitch and a wing-airflow simulator. The software also includes lessons which prompt students to engage in problem solving and discovery. The software was created to satisfy an objective to cultivate a more thorough understanding of the research being done at the NASA Lewis Research Center, while also filling a critical need for additional intuitive tools that supplement and enhance math and science curricula.

This program is an interactive flow simulator determines the airflow around various basic shapes of airfoils, including a flat plate. Several lessons on basic aerodynamics are included with this simulator package. The lessons are displayed in a separate window while the program is operating.

Here's a screen shot from the program showing the controls and displays:
