EMI resilient RF Photonic Links are critical for connecting remote antennas in the next generation Navy electronics warfare (EW) architecture. Current commercially available RF/photonic link technologies have deficiencies in dynamic range, noise figure, and SWaP performance. This STTR project aims to develop of a novel wide dynamic range, low noise RF photonic link, where the key component is a c ...

Corvid and the University of Virginia Center for Applied Biomechanics propose to continue the development of the CAVEMAN model as a tool to improve injury assessment capabilities for warfighters exposed to underbody blast loading events.  To ensure proper performance of energy-attenuating (EA) seat safety for warfighters, these systems must be designed to function across the range of anthropometr ...

The dynamic range of conventional, state-of-the-art ADCs is limited by the effective number of bits (ENOB) of resolution.  MagiQ’s SPIRAL uses novel techniques to overcome these limitations.  In this program we will combine custom hardware along with COTS hardware and proprietary MagiQ algorithms to significantly increase the ENOB.  The prototype system will far exceed the performance of sta ...

Hemp fibers are proven to be tougher, stronger, and more abrasion resistant than cotton. They are more sustainable, and UV and mold resistant, making it an excellent primary fiber in yarn and textile for battle dress, utility, workwear and outdoor wear.  Degummed, cottonized hemp can be blended with other fibers to bring out the best attributes of each and create new innovative yarns to manufact ...

Objective of the proposed work is the demonstration of scalable organic photovoltaic (OPV) devices with power conversion efficiencies of = 13% suitable for flexible light-weight substrates. Particular attention will be paid to stability, limiting performance loss to less than 10% to break-in over 100 hours unpackaged and 1000 hours packaged. Fabrication of such devices on flexible substrates is e ...

The main challenges in commercializing organic solar cell modules are translating the recently achieved high power conversion efficiency to larger area monolithic modules produced with scalable fabrication techniques, and improve operation lifetimes of the modules. Device degradation in organic solar cells can include intrinsic morphological changes over time, intrinsic chemical reactions at elec ...

Triton Systems Inc. proposes to develop an acoustic source capable of directly exciting structural resonances in a wide variety of targets on or suspended from the seafloor. The proposed method will provide unprecedented classification and identification information to the Navy. This technology will be useful for identifying manmade objects (such as mines and unexploded ordnance (UXO)) in the pres ...

Mine detection, identification  and classification especially of objects sitting near, on or just below the sea bottom in cluttered environments can be extremely challenging. Houston et. al.[1] demonstrated that it is possible to excite structural acoustic modes below 25 kHz and use these to identify mines. They concluded that multi-aspect scattering cross sections extracted over a broad range of ...

Triton is designing a combustor liner for a rotating detonation combustor (RDC) to suppress unwanted secondary waves that negatively interact with the primary detonation wave.  This passive design will target both radial and axial modes of acoustic waves generated in the combustor.  Triton will use computational fluid dynamics (CFD) simulation to design the acoustic liner and verify its effectiv ...

Physical Sciences Inc. (PSI) and University of Michigan will design, develop, and demonstrate a rotating detonation combustor (RDC) for gas turbine engine augmentors. This program advances a novel combustor design based on a unique geometric approach that addresses the stability and efficiency issues that have prevented RDCs from reaching performance metrics predicted by theory. Flow uniformity is ...
