used, which consists of a layer of micro- pyramids about 5 microns high. As Gochermann explains it, any light not absorbed by the surface of one pyramid will be reflected and hit a facet on a pyramid opposite, and be almost entirely absorbed. Even when sunlight strikes a conventional smooth solar panel at right angles, about 4% is reflected, but according to Gochermann the pyramid layer reduces this to a negligible 0.3%. At narrower angles of incidence, the efficiency of all solar panels drops as reflection increases, but Gochermann maintains that the pyramid surface limits this reflection to 4%, the same as a smooth panel at 90° to the light source. Additional sensors Operating at 12 V but with 12/24 V conversion capability, the electrical system can deliver up to 30 W for mission payloads, of which the company has tested a wide variety. “We’ve worked with current profilers, CTD sensors, acoustic modems, hydrophones and various other sensor sets,” Childress says. Payloads can be accommodated in three removable bays, and the bays can have openings in them to let water in and out for CTD sensors, for example. The ability to tow various payloads has also been tested. Above-surface sensors are also under consideration, with testing with gimballed cameras planned. A fixed camera system that fits on the masthead below the anemometer has already been developed, and enables the vessel to take images for 360° around it. Future variants Even more capable vessels are also planned, with the S200 (so named for its ability to submerge to 200 m) set to be available in the first quarter of 2017. Besides its greater depth capability, the S200 will also be able to travel and manoeuvre underwater, both as a buoyancy-driven glider and, thanks to its thruster, horizontally as a UUV. Ocean Aero is also working on a 40 ft variant with two wing sails, under a contract for the US Navy. It is to accommodate an undisclosed payload that will account for about a quarter of the vessel’s total mass, which it must be capable of jettisoning while underwater. “Dropping that much weight and keeping it from just going like that,” says Childress, gesturing to indicate something leaping towards the surface, “is quite an engineering trick.” With the fundamental issues of endurance, submergence and resurfacing now solved, Ocean Aero is focusing on expanding the capabilities of this new class of vehicle in areas such as scalability and the variety of payloads it can support and the missions it can undertake.
