NASA’s Quiet Supersonic Transport (QueSST) aircraft passed a preliminary design review last week, marking a major milestone for the agency’s experimental X-plane concept.

NASA has been developing new designs for supersonic aircraft, with a specific focus on reducing the strength of the sonic booms — the sound created by a shock wave from an aircraft that moves faster than the speed of sound. The shape and overall design of a supersonic plane are particularly important for minimizing the loudness of the boom during flight.

“The idea is to design the airplane so that the shockwaves that are produced in supersonic flight are arranged in such a way that you don’t have a boom, you have just a kind of general, gradual pressure rise, which produces a quiet sound,” Peter Coen, commercial supersonic technology project manager, said in a video from NASA’s Langley Research Center.
