Four Seconds in the Wind Tunnel by Prahalad

Four Seconds in the Wind Tunnel by Prahalad - October 2026 Scholarship Essay

At the Berkeley Engineering Youth Academy, I put a drone into a wind tunnel. It held together for about four seconds, then its frame snapped.

I had designed the drone, but I had not tested it under that kind of load. The broken frame gave me a question I could not answer by looking at the piece that failed: how were the frame, propellers, weight, and airflow affecting one another? I had thought about parts of the design separately. In the tunnel, they were all acting on the same system.

Professor Anwar helped me examine the problem without giving me a repair. That meant I had to work out what to change rather than copy a solution. I redesigned the drone and returned the next day. It survived the test.

The second test mattered, but I keep thinking about the first one. Before it, I could look at my calculations and feel finished. Four seconds in the tunnel showed me how little a design proves until it has been tested under the conditions it was built to handle. I wanted to understand what I had missed, and how a force on one part could change the behavior of the whole drone.

That question is part of why I like mechanical engineering. A design can look reasonable on a desk and behave differently once its parts interact under load. I want to get better at predicting those interactions, then testing the prediction instead of treating it as fact. The wind tunnel did not give me a long list of answers. It gave me a more useful question to carry into the next design.
