We propose the continued design, development and testing of spherical piezocrystal transducers and supporting technology including our gyroid transducer. The Phase II effort covers the modeling and demonstration of the gyroid transducer and comparison of performance with several piezocrystal and piezoceramic materials and testing in realistic environment. The electroacoustic performance will be es ...

Sonalysts will research and develop a robust military message profiler to permit automated local routing of incoming organizational messages transmitted to an activity by military messaging systems. Used at activities ashore and afloat, the profiler will parse and decode incoming messages and compare them with administrator and user-managed routing profile schema to determine which groups of end-u ...

The performance information contained in SMARTS and/or SolarWinds is not currently used to improve the uptime of the computer systems they are running on, or to help in quickly troubleshooting system faults/failures. In addition, due to limited size, current troubleshooting sessions are conducted between fleet crew onboard the LCS and SMEs on-shore using voice, email, and Secure Internet Protocols ...

The treatment of glyoxal with benzyl amine or allyl amine towards the formation of the corresponding tetraazaisowurtzitane cage structure has established a cornerstone in the preparation of caged nitramines and has led to significant research aimed at converting these precursors into compounds of interest such as CL-20. Although a route based on benzyl amine was briefly employed in small commercia ...

Preparation of caged nitramines has led to significant research aimed at converting these precursors into compounds of interests such as CL-20. This unique ability highlights the fine balance required from electronic and steric contributions in the formation of the cage structure. We propose to develop a low-cost alternative synthesis of CL-20 based on gaining insight as to the nature of this fine ...

Yardney will design and develop a lightweight, safe, reliable, and cost-effective aircraft battery with improved thermal design and the use of active cooling techniques. As a novel part of the battery design, Yardney will investigate and implement high performance electrodes using three dimensional (3D) micro-porous current collectors, safer thin metal case cell design, a micro-channel heat pipe t ...

Current Thermally Initiated Venting Systems (TIVS) consist of a thermal sensor, trigger, out-of-line blocking device, initiator, transfer energetic, and linear-shaped charge. TIVS reduce the reaction violence of munitions exposed to cook-off events by scoring the case of the rocket motor, not penetrating the case and igniting the propellant. The TIVS trigger should function when the rocket motor i ...

BTech proposes the design and development of a low-profile, broadband, shear-mode piezocrystal acoustic transducer for deep submergence applications. The Phase I effort considers evaluation of design variants of shear mode transducers with increased pressure operation/tolerance and tradeoffs associated with the same. Design feasibility is supported with calculations of expected performance and whe ...

A multi-band dual-aperture SATCOM antenna is proposed to support rotary-wing aircraft thru-rotor performance at X, Ku and Ka-bands including Ku-band TCDL as an option. Our proposed effort focuses on a low-cost design with reduced height and leverages existing aperture and radome technology from our prime contractor partner Lockheed-Martin. It also leverages existing digital modem technology develo ...

The Navy needs security-hardened Personal Electronic Devices for use in nuclear reactor rooms and other sensitive environments. Sonalysts and Cummings Engineering will develop a library of hardened and tested modules, extending and enhancing Cummings' Secure Agile Interoperable Framework for the Enterprise, SAIFE, to fortify the security weaknesses of the Android Operating System (OS) and its ...
