Wind Turbine Blades- Our Progression

As you may have read about in my recent blog, we are currently working on wind turbine blades in engineering class. My groups consists of two guys named Tanzim and Alex. We decided to create our wind turbine blades out of plastic cardboard because it's lightweight and sufficient. We decided to start off with a simple design of a width of 8 cm and a length of 20 cm. We created a rectangular blade and are currently still testing because we created various prototypes for out first prototype because we only had minor changes. (We had a prototype 1a and 1b.) It had taken us a while to complete our first prototype because it took us a while to consider each of our ideas. We've completed our first prototype and are moving on to testing. We haven't gotten too far ahead of what we initially thought we would have done by now. However, we're steadily moving further into the designing process. We're taking our time and being careful because one mistake could completely throw off our entire design. Below you will see pictures of one of our recent prototype, prototype b.
