One particularly eye-catching design for a fuel-efficient supersonic jet has captured the interest of NASA, which awarded the group behind the airplane a $100,000 grant to further explore its potential.
The design features a bi-directional flying wing with a shape that resembles a ninja star. The craft, thought up by engineers at the University of Miami and Florida State University, is symmetric about both longitudinal and span axes and would adjust to different speed modes in flight by rotating 90 degrees, according to the proposal.
