The Goal: Sweden to reach net zero greenhouse emissions by 2045
The Task: Design a clean and sustainable wind turnbine blade for use in a wind farm
The Constraints: 8.5mm < Blade deflection < 10mm
The Solution: Maximize blade efficiency while being eco-friendly
Soft Skills: Collaboration, Engineering Report Writing, Time Management
Technical Skills: Autodesk Inventor, ANSYS-GRANTA EduPack, Microsoft Office
Initial Research: The team gathered information about wind turbine blade design and shared the knowledge amongst each other
Problem Framing: The team met several times to properly define the problem, then came up with the objective, function, and constraints of our blade design
MPI Selection: The team chose the two main objectives to be minimizing energy required to manufacture the blade and minimizing CO2 production
Materials Selection: The team took the most common materials that showed up for each MPI then used a weighted decision matrix to choose our final material
Deflection Simulation: The team ran deflection simulations on various thicknesses of the blade to find allow maximum deflection of the blade
Role: I was the Subject Matter Expert
Responsibilities: I created and shared the collaborative working document for the team and completed the Source Materials Database
Expectations: Ensured that the team worked on the Project Report in a collaborative manner and that the sources used in the project are broad and reliable
Collaboration: I learned how to complete engineering projects as a team. I also learned that having multiple people helped getting ideas on the table faster.
Time management: Since Design Studio times were limited and always had milestones to complete, I learned how to more efficiently get things done.
Given that this was the first ever engineering project anyone in the entire team had really undertaken, all things went very smoothly. I think we all learned something about how to work better in a team and how to approach engineering projects in general.
