ATA Engineering has developed a wavelet-based damage squeezing methodology for generating optimally compressed fatigue test signals that produce an equivalent amount of fatigue damage in a predictably reduced amount of time compared to the baseline (uncompressed) signals. Fatigue-critical signal characteristics (e.g., magnitude, phase, frequency, and sequencing relationships) are identified in the ...

The region of the millimeter and submillimeter-wave frequency bands, from 100 GHz to 3 THz (wavelengths of 3 to 0.1 mm, respectively), are some of the least explored and yet information rich regions of the electromagnetic spectrum. This region of the spectrum, referred to as the terahertz (THz) frequency regime, roughly 300-3000 GHz, is ripe for development. A major impediment to development of a ...

This program will further the development of large area freestanding GaN substrates (150mm or greater) and develop a bulk GaN substrate characterization protocol to help reduce the variability in GaN homoepitaxial growth results which have prevented low cost, high voltage, vertical GaN power devices from being realized in an economically viable way.

Electromagenetic (EM) launchers could radically decrease the cost to launch and orbit micro-satellites and could provide launch with little lead time, but thus far it has not been feasible to achieve this capability with linear EM launchers. The objective of this research is to determine the viability of circular launch accelerators. Phase I explored designs consisting of a maglev sled accelerate ...

Our nation’s warfighters require advanced armor to give them the best protection while allowing mobility to perform their missions. This proposal will develop two powerful tools to aid future body armor advancements. First, this research program will develop a statistical analysis software that will predict likelihood of impacts based on defined attack scenarios (i.e. rifle, distance and firing ...

Palm-sized unmanned aerial systems (nano UAS) are emerging as a new tool for warfighters, first responders, and private industry. However, their small mass, fragility, and limited batteries still necessitate the use of emerging, low mass/power technologies to meet the full range of potential missions, including new autonomous flight control and collision avoidance strategies, structural improvemen ...

Exosonic develops supersonic commercial jets for airlines and proposes a USAF version. This aircraft flies at Mach 1.8 over 5000 nmi and carries 64-92 troops or 6 troops and 6 463L master pallets.

New, innovative laser spectroscopy technology will be developed for performance quantification and combustion characterization in a Rotational Detonation Rocket Engine (RDRE). The effort will push the state of the art in tunable laser absorption spectroscopy to enable fast time response diagnostics of the extreme pressure and temperature conditions of an RDRE.

Infrared counter-measures require a mid-infrared laser operating between 2-5 microns with time-averaged powers of 5W and more. Omni Sciences, Inc.'s (OSI's) Mid-Infra-Red FIber Laser (MIRFIL) will generate continuous light over the mid-IR, 2-5 microns, with time-averaged power scalable to more than 5W. The MIRFIL is a practical super-continuum (SC) source using commercial off-the-shelf (COTS) la ...

The NMR relaxometry instrument developed in Phase I project will be refined and thoroughly calibrated for nondestructive evaluation of the structure and properties of polymer-inorganic interfaces. The system design, operation conditions and data acquisition/analysis algorithms will be improved for precise and reliable evaluation of the structure and properties of the interfaces formed between dive ...
