Mark Kelm’s desire to build faster, more efficient machines began when he played with a toy gun as a child. That early flirtation with a toy grew into a science project that tests how airplane surface texture affects speed.
The Chesapeake Science Point freshman presented his science project at an aerospace engineering conference earlier this month.
The opportunity propelled him closer to his goal of becoming a mechanical or aerospace engineer. As an engineer, he hopes to solve problems and make better machines, he said.
The goal of the project was to find the wing texture that would optimize air lift. The project consists of a computer fan that sits on the end of a foam tunnel, which is covered with two pieces of glass taped together. A small scale sits in the middle of the tunnel.
At his Glen Burnie home, Mark places a smooth model airplane wing, mounted on a stick, on the scale and turns on the fan.
The weight of the airplanes starts to fall as the wind picks it up.
