Structure
|
The very stable primary structure is a lightweight with a weight
of approx. 1,000 kg (approx. 2,200 lbs). It consists of carbon-fibre trusses
in a triangular arrangement and three aluminum longerons that are tightly
wound by aramid ropes. All main components, such as the gondola, tail unit and
the propulsions, are mounted on this rigid structure. Thus, even in case of
pressure loss, an optimal maneuverability is guaranteed.

Envelope
Non-flammable helium provides the required lift
within the envelope that is made of high-strength multilayer laminate. The
envelope has a slight superpressure of 5 mbar. Air bags inside the envelope,
the so-called ballonets, keep the internal pressure constant in each flight
situation and ensure highest safety.
Swiveling propellers
Three propellers with a swivel angle of up to
120 degrees and a lateral fan, which is driven by the rear engine, enable best
maneuverability and an unrivaled, smooth and economical flight. The
capabilities of a vertical take-off, a precise landing, hovering on one spot
and a backward flight provide unique flight characteristics enabled by the
swiveling propellers.
Propulsion systems
Thanks to the inlying primary structure, the
engines are mounted on both sides and at the rear, where they can operate
efficiently. The in-flight comfort in the cabin is not disturbed by any noise
of the propellers or vibrations. Propulsion is achieved by three strong and
well-proven 197-hp aircraft engines.
Cockpit and cabin
The cockpit is a clearly structured high-tech
workplace equipped with latest avionics. "Fly-by-wire" control
systems with a sidestick enable precise maneuvers and relieve the pilots. A
mission display is available as an option. The cabin can accommodate 2 pilots
and up to 12 passengers. An adjustable cabin permits a quick conversion for different missions. A 360° panorama picture of the cockpits may be found
here.
Take-off and landing
The take-off and landing procedures, which are optimized by the
swiveling propellers, require a ground crew of only 3 members under normal
weather conditions. Advantages: lower employment costs and shorter "turn
around" times. The nose is decoupled from the mast truck when taking
off. When landing, the airship is self-maneuvering with the propeller thrust
into the desired position. In order to moor the Zeppelin, the nose line is
attached to the mooring mast line and the Zeppelin is pulled towards the mast.
