Lesson 3: Constructing a Model to Scale in Three Dimensions

 

Focus

 

In this photo a model of a joined-wing aircraft is being tested at NASA’s wind tunnel at the Langley Research Center.

NASA Langley/Sean Smith

Models of future aircraft are tested in wind tunnels, such as the pictured one at NASA’s Langley Research Center. Constructing and placing scale models in wind tunnels at each stage of development helps aeronautical engineers determine the forces applied and the performance of their designs.

 

In this lesson you, too, will construct three-dimensional models to a given scale.

 

Lesson Question

 

In this lesson you will investigate the following question:

  • How are three-dimensional models built according to a given scale?
