Fairing

As far as I can tell, the Seaglider is the only underwater glider that uses a fairing structure separate from its primary pressure hull. This design offers several advantages.

Firstly, the fairing provides a protective outer layer, shielding the pressure hull from mechanical damage and environmental exposure. Secondly, it allows for easier integration of external sensors and components, without compromising the structural integrity or sealing of the main hull.

Together with the wings and rudder, the fairing defines the external shape of the vehicle and therefore plays a critical role in its hydrodynamic performance, including drag, lift generation, and overall efficiency.

Implementation in Tuba

For the first prototype of Tuba, we are essentially using a geometry very similar to the SGX glider, which provides a well-established baseline for hydrodynamic performance.

Building on this foundation, future iterations may explore more advanced fairing concepts, including optimized surface geometries and adaptive or parameterized shapes as described in this paper or this one.
