Turbine Engine Design
Overview
Wind turbines populate the landscape in many parts of the world. These systems harness naturally abundant wind and transform it into electrical energy. Turbine blades efficiently convert wind energy into a force which turns a wind turbine. This energy conversion is an application of aerospace engineering principles. In this project my team researched, designed, created, and tested wind turbine blades

Procedure
1. Divide into groups of two under your teacher’s direction.
2. Research wind turbine blade design. How wind turbines transform energy from the wind? basic variables that impact turbine performance
3. Brainstorm blade variables
Variables may include:

3. Brainstorm blade variables
Variables may include:
- blade length
- number of blades
- weight/distribution of weight on blade
- blade pitch/angle
- blade shape
- blade material
- blade twist
DESIGN Sketches
Construction
- we made each part in inventor except
- we send it to the machine
- the machine printed our parts
- we glue the propellers to the stick or the stick holder
- we add it to the wind turbine and test it
Final designs/Results
First we 3d printed the propellers
then we glued the propellers to the sticks
we grabbed the turbine and put the propellers in them
finally we test its effectiveness

Best Voltage .70 at Angle .70 and fan speed high
How did your team come with the blade designs? by using research and taking influence from other models Did your team modify or change the designs? Why? How did the materials affect the performance? yes we have because at first we intended for all the designs to be cardboard but we decided that the last one will be styrofoam hoping it will be the best one Name some factors that made your final blade design better than the other two designs. it wasn't too big or too small better curved Describe the strengths and weaknesses of your final blade design. the strengths of my final blade is that its curved properly and it's width i s big enough to support the wind. weaknesses very low energy input and very unpredictable at high Explain what would improve your final blade design. to make it more curved and shorter and change the measurements a little bit. |
