"I enjoyed ordering what I needed. It was simple and fast, no issues what so ever. If I need something else and its at a good price, I will defiantly order from here again. Also the shipping is at a good price."

- Simon
My shipment arrived on time, as predicted. Very, very good performance by EcoDirect. What more could you ask for from an online material supplier? Looks like the quantity from Quick Mount is spot on & the rails were bundled safely. EcoDirect will be my recommended source to my friends & neighbors for solar.

Description
 

KidWind Airfoil Balsa Blade Wood Sheets

This balsa is pre-shaped in an airfoil shape. Real wind turbine blades use this airfoil shape to generate lift and reduce drag, making for highly efficient rotors.

Experiment with advanced blade designs and explore Bernoulliís Principle with these airfoil sheets. Well-designed airfoil blades will be noticeably more efficient than similarly shaped flat blades.

Sheets are 12 in. long, 3 in. wide, and 1/4 in. thick at the thickest section of the airfoil profile.

Length 12 in.
Width 3 in.
Thickness 0.25 in

You Can:

  • Cut and shape your own wind turbine blades
  • Experiment with number of blades
  • Experiment with size and shape of blades
  • Experiment with angle of blades

Concepts

  • Understanding differences between energy and power
  • Exploring concepts of lift, drag, and torque
  • Understanding angles
  • Developing and using physical models
  • Understanding the relationship between forces and motion
  • Understanding the relationship between energy and forces
  • Understanding clean energy
  • Exploring energy transformations
  • Analyzing and interpreting data
  • Optimizing designs
  • Designing controlled experiments
Frequently Asked Questions
  • How do I attach my blades to the dowels?

    We recommend hot glue (glue gun). Other types of glue or duct tape may also work.

  • How many sheets will I need for my classroom?

    Good question! This is one component of wind turbine experiments that is considered "consumable." We recommend starting students with simple, cheap materials like cardboard, paper plates, and cardstock. Then allow them to make advanced designs using the corrugated plastic. You can also group students into "teams" to save material. Most teachers use 50-100 sheets for a class of 30 students.

  • What is the best way to cut balsa wood?

    The balsa tends to split and break if you use scissors. Hobby knives work well; just be VERY careful. We recommend adult supervision.
