Feature 01 / 06

Rigid carbon lattice frame

Helical and hoop ribs form a stiff lattice that holds the hull shape at any fill level. Every frame variant passed nine load cases in finite-element analysis before selection.

Carbon lattice

Helical and hoop ribs in carbon fibre form the frame that keeps the hull rigid.

Vectoring pod

Each of the four pods tilts its propeller to push forward, up or down.

Mobile ground station

A remote operator follows the mission from a van at the route, with a ground handler when needed.

Autonomy

Planned missions, flown automatically.

An industry-standard open autopilot runs on a proven flight controller. Our own control allocation shares every command between the four vectoring propellers and the three fins. Waypoint missions, station keeping, a geofence and a link-loss failsafe are in development.

Bench-tested

Silent hover

Holding position quietly.

At low speed, the four vectoring propellers hold position and attitude on their own, turning slowly. That keeps noise down when the airship holds position over a target.

Bench-tested

Connectivity and positioning

Space-enabled operations.

Radio, 5G and satellite

Command and data run over radio and the 5G mobile network. A satellite terminal on board the X-11 is the back-up channel where coverage drops.

Design spec

Galileo HAS and OSNMA

20 cm-class corrections without local base stations, and authenticated position and time that protect against spoofing.

Design spec

Satellite weather data

Weather data in mission planning and rerouting, so the airship avoids conditions outside its limits.
