As wacky as it may look, Japanese scientists are taking a look at designing a modern-day biplane. K-cool!
A Supersonic Biplane that Whispers Where the Concorde Yelled

…a Japanese research group at Tohoku University…designed a modified Busemann biplane with moving wing sections…The Tohoku plane cut drag and sonic booms by employing ‘morphing wings’ that change shape in mid-flight to enable the plane to attain and sustain supersonic speeds (PDF).
Back in the 1970s, Boeing came up with a straight-winged, hypersonic biplane with remarkably low drag as shown on the right. Without the computational power to simulate it’s flight and design, it obviously was to radical to risk the expense to carry through beyond the concept drawing stage. It’s good to see some thinking out of the box coming from normally staid Japan.
