Massachusetts Institute of Technology's double bubble design in the wind tunnel at the NASA Glenn Research Center.

MIT's double bubble series design concept is based on a modified tube-and-wing structure that has a very wide fuselage to provide extra lift.

Massachusetts Institute of Technology's (MIT) H-series. The design features a triangular-shaped hybrid wing body aircraft that blends a wider fuselage with the wings for improved aerodyamics. The large centre body creates a forward lift that eliminates the need for a tail to balance the aircraft.
