Tewodros Assefa
DRIVEN ENGINEER ANDÂ LIFELONGÂ LEARNER
Since beginning my college journey, I've been driven to become the person my friends could call if they wanted to build some crazy contraption. An engineer worthy of the name and with the skills to back it up too. I am grateful for this journey taking me to exceptional people and projects that I became passionate about and I am proud to share some of my work with you. So take a moment to check out my portfolio and get in touch if you have any questions.

Formula SAE Front Wing Design
The Aerodynamics team of IIT Motorsports designed and manufactured the aerodynamic surface parts for the Formula E race car. This was done in order to guide the incoming flow of air and use it for cooling. I was put responsible for the design of the front wing allowing greater downforce and grip to be generated.
CubeSat Design
Integrating design principles and research methodologies for achieving NASA CubeSat merit and feasibility requirements.
Evaluated propulsion systems that can be utilized for a 6U CubeSat altitude change, orbit maintenance, and orbit shaping maneuvers
Designed a lightweight casing structure to house various components and withstand disturbances
Past Projects
Subsonic and Supersonic Testing
This class course gave me the opportunity to experiment and test airfoil response in a sub and supersonic wind tunnel.
Utilized a NACA airfoil to record the pressure distribution over subsonic a wing profile
Adapted the Schlieren experiment to identify supersonic shockwave angles and Mach numbers at various locations
Aircraft Design
This class project introduced me to the nature of development for new aircraft and design procedures to fall within requirements.
Designed a short take-off and landing attack aircraft capable of sustaining long recon flights and good maneuverability
Worked on landing systems and avionics design for the aircraft
Data Driven Modelling
This class project pushed me to explore the wide expanse of data-driven modeling and cover modern neural network architectures to create a hand writing analysis tool.
