This is a 1.79 percent scale model of a concept supersonic aircraft designed by The Boeing Company. You’re seeing it through a window in the supersonic wind tunnel at NASA’s Glenn Research Center in Ohio.
Researchers recently wind tunnel-tested the model’s performance while changing the amount of air streaming through inlets you can see near the back of the model, NASA said. The research is part of the agency’s work into making supersonic flights quiet enough to go over land.
