System reliability is a fundamental requirement for safety-critical weapons systems. A key challenge is identifying reliability problems early so that they can be fixed quickly and cheaply. Reliability problems are often integration problems: integration often reveals that flaws that seemed minor in isolated components but lead to serious system-wide reliability problems. The combination of static ...

The proposed project will develop three actively configurable metamaterial of relevance to both i) MDA’s high-priority and near-term need for stray light testing and diagnosis and ii) the interceptor functions of THAAD, Ascent Phase Interceptors, MKV and Space Systems. Phoebus’s configurable metamaterials aperture arrays will consist of single-layer metallic thin films patterned with light-cha ...

We propose to build a two-dimensional multi-pixel infrared detector based on rectenna technology. The rectennas comprise of a micro-antenna tuned to terahertz reception and an integrated Metal-Insulator-Metal diode. This system captures infrared radiation, rectifies it and converts it to a direct current for further processing. In this Phase II project, we plan to fabricate 2-D arrays of rectennas ...

ABSTRACT: We propose to develop an assured information sharing framework for cloud-based systems that leverages our ongoing work in the areas of policy-based usage management and semantic interoperability. The development of this framework will involve the creation of a novel approach to information sharing that treats security as a commodity that can be dynamically provisioned within the cloud, ...

Sensor networks embedded on structures, such as pipes, bridges, railways, aircraft wings and fuselage, among others, are required to transfer data related to the health of the structure. This data is typically sent to a central location where it can be processed, displayed, and analyzed. Typical Structural Health Monitoring (SHM) uses embedded ultrasonic transducers exclusively for non-destructive ...

The YSZ Environment Sensing (YES) sensor is an electrochemical sensor that offers temperature, oxygen concentration and pressure measurement solution in ultra-harsh environments common in hypersonic ground test facilities. Its key component is the yttria-stabilized zirconia, which has a history of being utilized as a thermal barrier coating for jet engines, will survive elevated temperatures beyon ...

ABSTRACT: RNET and The Ohio State University propose to use algorithmic modifications and multi-level parallelization techniques and tools to improve the scalability of the aero-line/aero-elastic coupled CFD/CSD codes relevant to the DoD/AF (e.g., CREATE/Kestrel). The optimizations will address inter-node and intra-node parallelization to better target emerging compute architectures (e.g., multi ...

Ocean surface winds are critically important in naval operations. They may aid, hinder, or negate maneuvers and operations, and are a primary consideration in routing ships. Continuous and reliable information on favorable and unfavorable sea state is critical for a broad range of naval missions, including strategic ship movement and positioning, aircraft carrier operations, aircraft deployment, e ...

To address the urgent need for 3D flash-lidar technology for landing on solar system bodies and for spacecraft rendezvous and docking with satellites, an effort is proposed to fabricate, characterize, and test a versatile, high-sensitivity InGaAs APD 3D flash lidar and to advance the technology-readiness level (TRL) of lidar technologies suitable for NASA mission requirements. Leveraging an existi ...

The Air Force is looking to improve calibration capabilities for instruments that measure flow and structure behavior in high speed airflows. Of particular interest is the flow regime where aerothermal effects are present, generally at speeds of Mach 5 and higher. High frequency oscillations in the incoming airflow are critical to the flow development around the vehicle so improved calibration for ...
