A newer version of the biplane aircraft created by Kazuhiro Kusunose and colleagues at Tohoku University in Japan, could make a comeback in the silent supersonic jets of tomorrow.
Biplanes once ruled the skies in the days of aviation at World War I.
With the new design the biplane could reach supersonic speeds without causing ear-splitting sonic booms.
“The sonic boom is really the shock waves created by the supersonic airplanes, propagated to the ground. It’s like hearing gunfire. It’s so annoying that supersonic jets were not allowed to fly over land.”
