KIDWIND AIRFOIL BALSA BLADE SHEETS 10 PACK
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 Bernoulli’s Principle with these airfoil sheets. Well-designed airfoil blades will be noticeably more efficient than similarly shaped flat blades.
Sheets are 300 mm long, 75mm wide and 6.4mm thick at the thickest section of the airfoil profile.
Sold as a pack of 10

FAQs:
Q Can I use this material for my blades in a KidWind Challenge competition?
A Yes!

Q How do I attach my blades to the dowels?
A We recommend hot glue. Other types of glue or duct tape may also work.

Q How many sheets will I need for my classroom?
A Good question! This component of wind turbine experiments is considered "consumable." We recommend starting students with simple, cheap materials like cardboard, paper plates and cardstock. Then allow students 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.

Q What is the best way to cut balsa wood?
A The balsa tends to split and break if you use scissors. Hobby knives work well; just be VERY careful. We recommend adult supervision.

Q Where can I learn more about airfoil shapes?
A Please read our Advanced Blade Design Manual View >>>>
