New gate goes up at Bat Cave entrance at Carter Caves state park
September 3, 2010
Roy Powers, a retired professor of electronic engineering, designed the gate, which is made of angle iron about six inches on each side. His design had to take into account flying space for the bats to get into the cave and also air flow. The angle iron bars have additional strips of steel welded inside to permit the air to slip smoothly past. It’s a design that has evolved over three decades, Powers said.
In fact, the design was tested in a wind tunnel to make sure it wouldn’t retard the free flow of air, he said. Less air flowing through the cave would change humidity levels, affect the bats’ environment, and possibly retard rock formations.
