Nevada company launches silent Sky Sentinel UAV airship
UAV’s, or Unmanned Aerial Vehicles, tend to face two issues – not being able to stay on station for long periods, and carrying enough of a payload to be useful. Nevada outfit Airship Manufacturing is introducing a new line of UAV airships, called Sky Sentinels, that promise larger payloads with greater endurance, as well as being adaptable, modular, and economical to operate. And they do this without any wings.
As a UAV, these lighter-than-air vehicles offer large payload modules, multiple sensor attachments (as many as eight per payload module), significant electric power, and endurance measured in days rather than hours. As a bonus, the airship can be very quiet, providing a near noise- and vibration-free environment for finicky sensors.
