A novel hybrid acoustic emission (AE) and guided wave (GW) inspection approach for radar towers inspection is presented. Keeping aging radar sites (many are over 50 years old) in good repair is important because they are critical intelligence components that provide advanced aircraft notification. This proposed work will continue development of new, patent-pending shear-type AE sensors, and apply ...

Sudden structural failure caused by stress corrosion cracking (SCC) in aircraft components is becoming a severe safety threat to Air Force aircraft and other aviation vehicles. Detection of SCC often occurs late in the damage development cycle, in which fast-growing macroscale cracking has already developed. This significantly increases depot maintenance cost and can negatively impact aircraft ava ...

This phase 2 proposal builds upon Phase 1 successes, with plans for the construction of an electrochemical variable emissivity device (EC VED). The viability of this EC VED will be determined by the development of a new family of ionic liquid (IL) electrolytes featuring polyhedral boron cages as the anionic component. In these new electrolytes, the negligible vapor pressures and high ionic conduct ...

Kyma Technologies, the leading domestic supplier of crystalline III-N substrate materials, is teamed with leading AlGaN materials & device experts at Sandia National Laboratories (SNL) to develop high-quality n-type conductive 2-inch diameter epi-ready free-standing AlGaN substrates in support of next generation AlGaN devices with applications in ultraviolet optoelectronics, power electronics, and ...

In December 2014, the DoD CIO directed that military services manage the migration of their respective applications from dedicated data centers owned and operated by the respective services, to the commercial cloud. This directive included processes and procedures to expedite the process and is a driving force behind the US Air Force (USAF) data center consolidation initiative. Consequently, the U ...

The Bennett Advanced Research Team proposes to create spacecraft structures embedded with wires and other sensors creating a multifunctional structure.

This program is the next step in the development of a wideband dual polarized HF antenna covering 3 to 30 MHz supporting transmit and receive functions with instantaneous bandwidth of 10 MHz. A prototype design was developed in Phase I of this program. This design included the use of lossy impedance matching techniques for the horizontal and vertical transmit antennas. This ground based antenna de ...

Theater Weather Imaging and Cloud Characterization Sensor (TWICCS) payload for the MetNet-1 Small Satellite will demonstrate the capabilities of a push-frame, multispectral imager in acquiring high quality weather data covering from the Visible through Longwave Infrared. Data products supported include Theater Weather Imaging products (ie. discrimination of ground fog, dust, and smoke, etc.) and C ...

Corvid Technologies approach for improving munition technologies is to design an asymmetric shock propagation barrier (ASPB) with reactive composite materials (RCM) to enhance functional and lethality characteristics over traditional shock attenuation barriers. In Phase I, we teamed with Shock Transients Inc. (STI) to develop, evaluate, and fabricate a two-layer ASPB concept using MPXITM, an RCM d ...

Interfaces on existing military chemical/biological protection garments are not designed to fully eliminate macroscopic and microscopic air gaps at folds, fabric surfaces, or hook-and-loop closures, and thus do not provide a hermetic barrier against exposure. Creare is developing hermetic garment closure systems that seal macroscopic and microscopic gaps at interfaces and closures and provide high ...
