Small-Scale Velocity Turbulence Sensors for Undersea Platforms

Areté Associates proposes to design and build a robust and rugged turbulent velocity sensor for navy use on a variety of underwater platforms. Using a combination of physics based modeling and prior experience designing, building, and operating submarine based sensors and oceanic turbulence and microstructure systems, we will produce a new sensor design meeting Navy requirements for submarine and UUV integration and operation (exposure to harsh environments, operation at speeds up to 5 knots, impact resistance) which produces measurements of 3 orthogonal velocity components over the specified frequency band of 0.025–250 Hz in a variety of flow conditions. This new sensor will provide the Navy with reliable measurements of oceanic turbulence, complimenting existing environmental measurements made from submersible platforms while extending environmental sensing capabilities of existing and future Navy undersea platforms.
