Dartmouth Ocean: V-Wing Towed Underwater Depressor

The V-Wing towed underwater depressor enables users to conduct underwater research, inspection, and reconnaissance quickly and economically. V-Wing’s unique dihedral wing design enables rapid descent to unlimited depths, provides stability for added mission accuracy, and minimizes drag for increased efficiency.

Portable Underwater Mapping, Research, Inspection and Reconnaissance

Unique Wing Design

The V-Wing creates a hydrodynamic flow over its unique wing design to produce a depressive force that pulls down many times its own mass (typically a 5:1 lift-to-drag ratio). The V-Wing’s unique dihedral wing design enables rapid descent, submerges to unlimited depths, stability during operations, and minimal drag.

Reduce Potential Failure

By eliminating the need for motorized propulsion, V-Wing reduces potential points of failure, product weight, and component costs.

Technology Flexibility

The V-Wing’s self-contained towed body also provides the flexibility to mount a variety of marine technologies for commercial and government applications.

Intuitive Operation

A moving command ship can receive real-time transmissions from V-Wing via a connected cable. Operators control V-Wing’s set depth based on the length of cable in the water and boat speed. To simplify operations, a software program helps operators determine appropriate V-Wing depth.
