The Flying Wing Autonomous Underwater Glider Technology
The invention offers the ability to do long range roaming in combination with adequate speed capability to penetrate strong ocean currents.
This vehicle is useful for basic science applications such as monitoring fisheries, marine mammal populations, or waste field discharged by offshore outfalls, as well as both civilian and military applications.
Researchers at UC San Diego have developed a new class of fully autonomous underwater gliders optimized for long distance and long duration (persistent) flights in the ocean. The design uses the high lift-to-drag ratio properties of flying wings in order to maximize horizontal transport efficiency and significantly increase the speed and payload/cargo-carrying capacity of underwater gliders. The flying wing gliders have 20-ft wing spans and total internal volume in the 1,000 liter range. They are equipped with passive acoustic and oceanographic sensors, and very-low-power embedded computers for real-time processing of the sensor signals and for flight control. Navigation systems include GPS while on the surface, and a depth sensor, an attitude-heading reference sensor, and very-high-frequency velocity sensor while submerged. Satellite communications as well as high-data-rate line-of-sight communications are available while at the surface, whereas two types of underwater acoustic modems can be used while submerged.
