GLADAN · H4.0
An enclosed-rotor hexacopter.
Six shielded rotors, a faceted composite shell and a hybrid powertrain. GLADAN exists today as a complete CAD model; the images on this page are rendered from it.

Design
Why it looks like this.
Nothing exposed
Rotors, sensors and harnesses sit inside the shell. Safer around people and structures, and a cleaner silhouette.
Faceted, not rounded
Planar composite panels with recessed windows and louvres, shaped to reduce visual and radar signature.
Fuel for endurance, batteries for response
A range extender charges buffer batteries. Station time comes from the tank, control from the cells.
