Communication from ocean-surface sonobuoys to airborne platforms is critical to Anti-Submarine Warfare (ASW) operations. Existing Radio-Frequency (RF) solutions encounter several challenges which Free-Space Optical (FSO) systems solve. FSO systems for sonobuoy applications have unique challenges that proper system design can overcome. Verdant Networks is proposing an asymmetric system design that ...

Agiltron Inc. proposes to develop a compact, sensitive, and selective tunable diode laser absorption spectroscopy (TDLAS) based multi-gas sensor for OBOGS breathing oxygen monitoring. In the proposed research, novel laser diodes that output wavelength tunable from 2000 nm to 3500 nm will be used to dramatically increase the number of gases that can be detected and improve the sensitivity achievabl ...

Our proposal specifically addresses the stated requirements of the solicitation; we will develop and deploy tools and methods for efficiently collecting, analyzing and classifying narrowband signals within a wide radio-frequency spectrum. The number of potential hostile waveforms in the RF environment will continue to increase with an essentially random distribution. However, at any given time, th ...

The research objective of this proposal is to perform computational alloy development to enhance the Ti-6Al-4V chemistry for direct digital manufacturing (DDM). The new alloy will be designed to attain the following attributes: (1) isotropic behavior with mechanical properties on par with the upper bins of Cast+HIP Ti-6Al-4V; (2) ability to deposit builds within a window of processing conditions c ...

Intuitive mission display visualization and planning capabilities are needed to enhance operator situation awareness when supervising teams of unmanned vehicles. To address this need, we will design and demonstrate Advanced Mission Display and Planning Tools (AMPT) to reduce the workload of re-planning and re-tasking teams of heterogeneous vehicles. These decision-support interfaces will use simpl ...

Future operations will increasingly utilize unmanned vehicles (UxVs) to accomplish complex missions. UxV"s have the potential to dramatically improve real-time situation awareness and increase mission success. Current advancements in performance and capabilities of UxVs and automated mission planning systems are enabling a shift from direct teleoperation towards supervisory roles. With this shift, ...

Mezzo Technologies fabricates high performance micro tube heat exchangers. In this proposal, Mezzo proposes to fabricate a heat exchanger to interface between helium, which is the working fluid used to cool a variety of superconducting components on Navy vessels in the future that will require cryogenic cooling, and cold neon gas, which is supplied by a Reverse Brayton cryocooler. Mezzo's app ...

Retractable mooring fixtures are a critical component on the flight deck of a DDG51 class Navy ship. The chocks and bitts must be recessed below the deck level for helicopter operations, while reliably and easily deployed for mooring situations. The current mooring fixtures do not stand up to the highly corrosive environment of the flight deck and the lack of maintenance reduces the reliability of ...

The primary objective of the proposed research is to develop, and to demonstrate the feasibility of a mathematically rigorous approach for modeling and evaluating human supervisory control of multiple unmanned and/or autonomous vehicles. This high-level objective is decomposed into three inter-related goals: (1) the development of a mathematical model of human supervisory control, for individual o ...

Arrays of vector velocity sensors have exhibited major system improvements over traditional omnidirectional hydrophones in undersea acoustic sensing. Compact accelerometers made from relaxor piezoelectric crystals are the key element which allow for the improved functionality of the vector velocity sensor arrays. These relaxor piezoelectric crystals are extremely sensitive and compact; but manufac ...
