What made the Deltoid Pumpkin seed different than a Zeppelin or modern blimp?

It had a rigid frame, like a zep, but it was delta shaped. "Pumpkin seed" was because it was painted orange. iirc, one or more of the team were Princeton graduates. Princeton's school colors are orange and black.

The craft survives, in a museum in New Jersey. Pix at the link.

The AEREON 26 was an experimental aircraft developed to investigate lifting body design. Using its shape to create a hybrid design, the prototype is part airship, part conventional aircraft. It was powered by a piston engine, driving a pusher propeller, and generated lift through the aerodynamics of its lozenge-shaped fuselage.

This video discusses the earlier, triple hull craft, that I first saw in Mechanix Illustrated. As the video says, the craft was rolled over by a strong crosswind during taxi testing, and destroyed.
