Today was a bitterly sweet day. To start off the day, I visited the supersonic and subsonic wind tunnels, the anechoic chamber, and the test cell. Supersonic wind tunnels can produce wind speeds that are faster than the speed of sound. Subsonic wind tunnels produce wind speeds that are less than the speed of sound. While in the subsonic wind tunnel room, the professor allowed me to stand inside while the wind tunnel was going at its maximum speed. Also inside the room were some jet engines that could spit fire and an actual airplane wing. Next, moving onto the supersonic wind tunnel. Supersonic wind tunnels can produce wind speeds that are faster than the speed of sound. The way NC State’s supersonic wind tunnel worked was by using bursts of compressed air aimed through a narrowing chamber. This supersonic wind tunnel could only run for about six seconds at a time.
Next, I was led to an anechoic chamber. This three-doored room had numerous triangle pieces of foam lining the room. Standing inside, it was so quiet that I could hear my heartbeat. Below is a picture of an anechoic chamber, similar to the one I visited today.
Next, I was led to a test cell. These are rooms where jet engines can be tested. They are extremely fireproof and have a great ventilation system.
At the end of the day, at a group meeting, I gave my presentation on OpenVSP and what I had learned over the last two weeks. I have attached my presentation below. We then continued to try and learn GitHub.
This was the end of my amazing work experience and I was extremely sad to say goodbye.
