Benefits of technology
The design achieves significant hydrodynamic efficiency with reduced weight and complexity, capable of withstanding high pressures while maintaining control over pitch and vertical motion using a single actuator, and ensures reliable communication and operation in underwater environments.
Problems solved by technology
However, these cylindrical or spherical shapes are not hydrodyamically efficient compared to more streamlined shapes.
One solution to this tradeoff between pressure resistance and hydrodynamics is to add an external hydrodynamic shell around a pressure hull; however, this solution adds weight, complexity, and cost to an underwater vehicle.
There are no known designs for a submersible vehicle that provide a hydrodynamic shape for the pressure hull itself.

A submersible remotely operated vehicle with a streamlined shape, which uses an internal support lattice to provide pressure resistance. By using a lattice frame to distribute the water pressure load on the vehicle, the vehicle may be constructed of thin-walled, injection molded plastic, yet may be capable of diving to significant depths. The vehicle may provide pitch control using a single vertical thrust actuator that is horizontally fore or aft of the center of vertical drag; this efficient pitch control improves hydrodynamic efficiency by pointing the vehicle towards the direction of travel to minimize the coefficient of drag. The vehicle may communicate wirelessly with a remote operator via a communications buoy tethered to the vehicle, thereby eliminating cabling constraints on the vehicle's range from the operator. The tether may be connected to the buoy using a waterproof connector that presses three terminals surrounded by a compliant seal onto mating contacts.
Description
[0001]This application is a continuation of U.S. Utility patent application Ser. No. 15 / 285,255 filed 4 Oct. 2016, the specification of which is hereby incorporated herein by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]One or more embodiments of the invention are related to the field of underwater vehicles. More particularly, but not by way of limitation, one or more embodiments of the invention enable a remotely operated submersible vehicle with a hydrodynamic design that incorporates an internal support lattice.Description of the Related Art[0003]Underwater vehicles such as submarines must be designed to withstand the pressure of the underwater environment, which can be extreme at significant depths. Therefore these vehicles are typically designed with pressure hulls that are cylindrical or spherical, since these shapes provide inherent rigidity due to their circular cross sections. However, these cylindrical or spherical shapes are not hydrodyamically efficie...
