Physical Sciences Inc. (PSI) and their academic partner, West Virginia University (WVU), are pleased to propose a uniquely innovative approach to measuring the three-dimensional air wake velocity field behind ship structures and towers. The velocity data is needed to support the validation of CFD models that will ultimately be used to provide sufficient safety margins for ship aircraft operations ...

Although advancements in CFD technology and high performance computing have proven to be effective and reasonably accurate in assessing the hydrodynamic performance of naval vessels, the effort required to develop associated analysis models remains a challenging and time consuming task. Decomposing and manipulating the design geometry for mesh construction, while capturing near-field and far-field ...

Current atmospheric diving suits and remotely operated vehicles (ROVs) have end effectors with simply 1 DOF. This rudimentary manipulation results in excessive time spent working a problem underwater, development of task specific tools that can be operated by the pliers or acceptance that a specific job simply can't be accomplished. Vishwa Robotics proposes a teleoperated, anthropomorphic end ...

Green laser sources are important in advanced naval mine detection as this wavelength has good penetration though seawater. Mine detection programs such as the Coastal Battlefield Reconnaissance and Analysis (COBRA) system and the Airborne Laser Mine Detection System (ALMDS) currently use frequency-doubled 1-µm lasers as the laser source. The generation of green laser light via frequency doubling ...

Autonomous systems continue to be outfitted with larger amounts of sensors that are capable of collecting extremely large amounts of data over the course of a mission. Even autonomous systems with high storage capacities can run into storage limitations when burdened with large amounts of sensor data over long mission durations. This proposal will develop a Learning-based Approach for Relevant Dat ...

The proliferation of laser based weapons systems has led to the need for laser threat sensor systems that operate over wide spectral range from the visible to infrared and provide sufficient dynamic range to measure the irradiance levels seen in practice. OPTRA, Inc. proposes a solution based on the complementary combination of CMOS readout integrated circuitry and diffractive optics to provide th ...

We envision a coherently coupled QCL array architecture featuring 2nd order DFB gratings to vertically couple out light with excellent beam quality and high output power. This approach does not require cleaving of the devices or facet coatings and is therefore inherently more robust and manufacturable than facet emitters.

Vescent Photonics proposes to develop a compact laser system and integrate it with a cold-atom micro primary standard developed under the DARPA IMPACT program. In phase I we will investigate performance enhancements resulting from immobilizing the cold-atom sample with an optical lattice formed from an optical field whose wavelength is chosen to minimize the differential light shifts between the s ...

This research seeks to develop a method of developing solid-state power amplifiers that operate at 300 Volts, achieve 100 Watt output and greater than 90% efficiency at 1 GHz with 10% bandwidths. We will seek to demonstrate switch-mode amplifiers that use a novel gate design with Gallium Nitride forming the basis for solid state power amplification.

The Navy seeks to develop new, innovative motor/generator technologies that can effectively operate at speeds up to 1,000 kRPM at power densities of 40 kW/kg (excluding heat exchanger) with an overall system efficiency of 95% or better. Such a motor/generator will have a wide range of applications, i.e. it can be used as the core building block of a very lightweight electrical energy storage syste ...
