  • Zeppelin framework

    The De Beers aircraft is Zeppelin NT-07. The New Technology Zeppelin, which had its maiden flight in 1997, has framework that weighs about a ton. The cabin, engines and other main airship components all connect to the rigid structure, which has triangular carbon fiber frames and three aluminum longerons.

  • Envelope

    The envelope of the NT airship, made of many layers of laminated fabric, holds helium gas.

  • Propellers

    Three propellers with a maximum swivel of 120 degrees aid the Zeppelin NT to take off and land vertically, like a helicopter.
