Ignition of rocket motors can be performed using low-volt firing components, but MIL-STD-1901A requires mechanical isolation for safety. While traditional safe & arm devices are available, they are relatively large and heavy. Recent progress in MEMS has developed miniature safe & arm devices for low-cost munitions such as 40MM grenade and airburst munitions. The Black Hills Nanosystems team has ...

We propose creating a new company to deliver accelerated graph-based analytics for modern manycore systems. The work combines advanced multithreading and work-moving typical of HPC but targeted at cloud environments with insight into the structure of the graph to improve spatial locality and an attribute-first query system to dramatically reduce the work required to solve practical graph problems ...

The main goal of Phase II is to validate the Phase I prototype and develop an integrated design and analysis tool for assessing large damage and blends for compressor IBRs on gas turbine engines and other blade systems. This tool will have at its core the automated analytical modeling of as-measured or as-expected airfoil blends for the structural and aero response to the shape change due to blend ...

A method of utilizing 3D printed molds to produce low cost metal parts for obsolescence, engineering development prototypes, and low rate production is proposed for development and evaluation.This method is capable of producing parts of similar quality to mass production techniques such as green sand and lost wax casting at a fraction of the setup costs for those methods.

In response to Defense Logistics Agencys SBIR for Advanced Manufacturing Technologies, Sentient proposes to develop a life-cycle cost optimization tool based on its DigitalClone-ComponentTM (DCC) modeling technology.This tool will enable users to better understand the tradeoffs between manufacturing cost and performance/durability of the resultant components. This is particularly attractive for lo ...

This proposal is for the development of a unique, ultra-portable, low-cost, hand-held high-pressure cold spray system for repairing cracks on aluminum structures on surface ships that were damaged by corrosion, based on a patent-pending cold spray device which has already be developed for shop or laboratory based applications. In the cold spray process, powder particles are accelerated by a supers ...

This proposal is for research into various configurations to reduce or eliminate the drag and resulting lateral loading that result from the shotgun connector and evaluate the potential overall weapon system improvement by simulating the trajectory of the improved system. Three configurations will be studied by computational fluid dynamics to estimate aerodynamic properties and utilized to simulat ...
