Vertical Axis Wind Turbine
Description
This Is A 340Mm Diameter Prototype Vawt That'S Intended To Be A Scalable Demonstrator. It Accommodates 3 Blades Which Are Stolen Directly From Scrap Vinyl Vertical Blinds. (Yes, Those Ugly Fat Ones That Hang) You Just Take The Single Blinds And Insert Them In To The Slots. I Put A Dab Of 2-Part Epoxy To Keep Them In Place, But The Fit Is Tight. The Blade Arms Attach Via 3X 3Mm Screws Or Bolts. The Central Hub Is Sized To Use A 7/16 Shaft (I Use 1/2" Threaded Rod That'S Cut Down With A Lathe In Just The Right Place So I Can Put A 1/2" Nut Below To Support The Turbine). Note That There'S A 20-Tooth Gear Face On The Hub, If You'D Like To Drive A Mechanism- Though I Doubt You'Ll Power More Than Landscaping Lights Until This Is Optimized. That Being Said, I Have Included The Solidworks Part Files So That You Can Change The Blade Angle, Etc. If You'D Like. Oh, And You Could Print More Than One Set And Drive A Multi-Tiered Version With Really Long Blinds If You Like!
