Wind Tunnel Testing | Project Sierra Log#2
The wind tunnel had its first successful test!! On the 21st of January 2023 at 3:17 pm Project Sierra had its first successful test where I tested the aerodynamics of a model of a Lamborghini Aventador and a Bugatti Divo. After the initiation of the project’s construction back on October 6th, 2022 it has been a long wait for the required parts, but it was Worth It!!
In all honesty, the Lamborghini did not test well even though it definitely looked like the better of both models, aerodynamics-wise. Granted there are definitely a lot of modifications needed to make the wind tunnel run to an optimal level. The following are the improvements currently being made:
I’m currently 3D printing a stand to raise the test model to a level, where the test model will be in the middle of the test chamber to receive the most pressurised air
Higher and stronger support for the wind tunnel as the current support nearly collapsed after testing
To find the optimal RPM of the fan (I can adjust it thanks to my booster module)
To reduce the amount of fog emitted by the fog machine to keep the test object actually visible rather than in a puff of smoke
Although the wind tunnel currently has its flaws, I still consider it a victory as the air managed to remain streamlined and I managed to actually keep it airtight!! Moreover, I don't think a lot of 17-year-olds have built wind tunnels with the calculations to recieve optimal data on drag, and airflow around the object. I also added a 3D-printed scissor lift to bring the test platform up to the wind tunnel. I cannot wait to test more models and maybe even test a few that I developed.
Project Sierra is undoubtedly a major milestone for me!!
