At her aerospace engineering elective, high school senior Keren Araujo shows off the latest creation.
“We’re designing airfoils — they’re like the wings of a plane,” explained the 17-year-old. After Araujo and her fellow students put the finishing touches on their wing designs using a computer engineering program, they’ll ship the dimensions to the classroom’s 3D printer and create more model wings.
She then points to a tube about a foot wide and the length of a student. “This machine simulates the flow of wind — it’s called a wind tunnel,” Araujo said. She’ll use it to test whether her airfoil will fly through the air efficiently.
