The Dirigible

1899

Ferdinand Graf Zeppelin

Zeppelin’s “Navigable Balloon” provided several improvements to lighter-than-air craft of the day. In particular, he invented the “rigid frame” dirigible.

He installed a moveable weight that would tilt the air ship up or down to allow it to ascend or descent. He used short rigid units to contain the gas bags. These units were attached at one point to allow the ship flexibility along its length. Also, he incorporated auxiliary gas bags for maneuvering.
