Hi,

Video produced by Team Trinity - students at the University of Central Florida, California's Chaffey College and the University of Technology in Sydney, Australia - showing their Artemis concept for a small supersonic airliner. Trinity tied for second place in NASA's 2009 design competition for college and university students. Artemis has a single-pilot cockpit; composite-isotruss airframe with no windows - large OLED displays in the cabin replace the windows; constrained-span wing for reduced drag and noise; and shielded engines.

Interesting that many teams used loop wing concepts. The Trinity team's use of a parabolic upper wing like some of the early ATF supercruiser designs is an interesting twist, though since it is not forward swept it isn't your typical box wing. The indian team's use of a joined tail is closer to a box wing, and makes convenient use of the engine pod's monolithic afterburner as a structural mount. And as I suspected, the last picture (the Ohio team), is a busemann biplane. I wonder if a busemann biplane may be quieter, since it technically falls under the class of boom-eater.

No telescopic noses, but a lot of canards, and the winning Tokyo team had a liquid hydrogen entry (the japanese seem to have a bit of an obsession with hydrogen fueled airliners).
