There is a need to achieve 10^-9 reliability for actuators for critical aerospace applications and this precludes single point failure for all but the simplest and most reliable electrical and mechanical components. LC Drives proposes a method of constructing a high reliability linear actuator for critical aerospace applications that is designed such that jams caused by conventional electrical a ...

ABSTRACT: Silicon Technologies, Inc. (STI) proposes to extend the results of a DARPA sponsored contract # W31P4Q-11-C-0046,"Design Tools For Highly Regular Circuit Geometries"to develop a set of design tools and analog cells specifically for use in automating the design of Rad Hard analog circuits. STI was able to prove feasibility of a revolutionary new set of design tools for analog design. Th ...

Fiber reinforced composites are attractive for several light-weight defense and aerospace applications. However, their inherent anisotropy and complex failure mechanisms limit their use in high-performance structures or components. In order to accurately predict the damage behavior and durability of composite parts exposed to extreme conditions, there is a need to develop new analysis tools that c ...

The synthesis of ammonia through nitrogen fixation is a vital component to all plant life and the world economy as a fertilizer and commodity chemical. The global industial production of ammonia exceeded 140MM tons in 2009 and is expected to grow to 160MM tons by 2020. Most ammonia,>90% is synthesized through the Haber-Bosch processThe Haber-Bosch process produces more than 90% of the industrial ...

ABSTRACT: This effort seeks to identify an effective paint remover that does not contain Hazardous Air Pollutants (HAPs) and does not interfere with the metal removal process at the Hill Air Force Base Industrial Waste Water Treatment Plan (IWTP) while also meeting mil-spec requirements for aircraft landing gear maintenance. Aircraft maintenance activities generally involve disassembling major co ...

DRS Scientific proposes a new type of Acousto-Optic Tuned Filter (AOTF) polarimetric hyperspectral imager that is compact, rugged, and inexpensive, has no moving parts, is free of optical aberrations, and is fast and sensitive. It will cover 8-12 mm with 8 cm-1 spectral resolution or finer, and will have mFlick sensitivity with a cooled camera, and

This proposal describes an innovation for making bulk nanocrystalline tungsten alloys that will be sufficiently ductile and meet mechanical properties targets set by the army. Tungsten (W) and its alloys are primary candidate materials for next generation munitions and warheads owing to its high density, high modulus, and other favorable properties such as benign environmental impact. The actual u ...

ABSTRACT: The U.S. Air Force has a critical need for new robust strain sensors capable of accurately measuring the strain of structural components in high temperature harsh environment applications. During Phase I, Environetix will leverage extensive experience in wireless high temperature sensor materials, devices, packaging, and data acquisition, to develop and lab-test a prototype surface aco ...

ABSTRACT: This proposal describes an analytical software approach to model rolling element bearings for gas turbines and similar drive systems. Detailed approaches for modeling bearing material fatigue life, oil churning, and tribology are presented. The resulting analytical bearing code will enable gas turbine engineers and designers to better assess engine lubrication system thermal loads and ...

Phase I of the STTR program will be a collaborative research effort between high fidelity computational simulations and experimental testing. The primary aim of this initiative will be to measure laser beam distortion, using aero-optic metrics, due to flowfield turbulence. The results from the computational simulations and experimental test will be compared to ensure agreement between the two. Ini ...
