Today we visited Inholland, a University of applied sciences with a branch in Delft. We got to learn about the aeronautical engineering program that this branch has, which I found interesting as an engineering student myself. We started with a couple of presentations about the university as well as aeronautical engineering. This second presentation went over the history of aviation, from the early days of innovation to commercial flight to the modern struggle for more sustainable flight. One area that is being looked into hydrogen/electric flight, using both in order to replace traditional jet fuel. Another, smaller, older innovation was the addition of winglets to planes. These help reduce the power of vortexes at the edge of a plane’s wings, reducing drag which in turn reduces fuel use. This is another example of in o creating more sustainable flight, as less fuel use means less emissions into the environment. This goes with the idea of being more sustainable helping businesses, as this innovation was initial made due to the oil crisis, a time where get fuel was scarce. So, this was due companies trying to save money rather than being sustainable, but it had the same sustainability benefits regardless. After this we had lunch, followed by a quick tour of a couple of different areas the campus had, such has a test flight simulator, composite lab, and a work area for the students. At the composite lab we learned about the university’s work in designing a satellite, part of which was a parachute that deployed after 3 years to make sure the satellite came back to earth. This part was created to help prevent more garbage from entering orbit, as too much debris could cause a chain reaction of collisions making space flight impossible. This thing ties back to sustainability, as only by properly managing how we use our satellites will we be able to continue to send them into space and use them. After these tours, we had a competition to see which team could build the best glider using foam and a few other materials. Our team didn’t win, but I feel like I learned a bit about plane design and team work. After this we went to a restaurant to get milkshakes, as well as finally getting to experience the infamous Dutch rain. It has been almost completely sunny for the rest of this trip, so having it finally rain was a change of pace. To end the day we had another canal cruise, this time of the city of Delft. This tour was also nice, and we got to learn a bit more about the city. Overall, I think that today was a rather informative experience, as I got to learn more about sustainability as well as a branch of engineering that I haven’t had much exposure to.
