ABSTRACT: Many turbomachinery applications have achieved improved availability, reliability and cost savings by incorporating health monitoring systems to determine the mechanical condition of key components in near real time. The goals of any health monitoring system are to ensure reliability by avoiding unplanned maintenance, to reduce operating costs by providing the information needed to plan ...

ABSTRACT: The Air Force spends $4.5 billion annually on aircraft maintenance related to corrosion.The source of this corrosion frequently is airborne chlorides that settle on metal parts and sensitive avionics and then absorb moisture from the air to create an electrolyte that promotes galvanic corrosion.The proposed work will design, fabricate and test a Corrosion Mitigation System (CMS) that sup ...

ABSTRACT: The objective of the effort is the development of a Femtosecond Laser Electronic Excitation Tagging (FLEET) system and data analysis tools for the measurement of transport parameters in nitrogen and air ground test facilities without seeding the flow with either particles or with foreign gases.  The effort follows Phase I accomplishments, wherein a transportable FLEET laser system with ...

ABSTRACT: SIFT's Phase 2 Hy-CIRCA proposal builds on progress in Phase 1 to address the challenge of effectively, reliably, and safely tasking cooperating teams of autonomous cyber-physical systems (CPSs). SIFT's Playbook(tm) interface approach provides high-level, goal-based tasking for multi-agent autonomous missions. SIFT's Cooperative Intelligent Real-Time Control Architecture (CIRCA) automa ...

As stated in the solicitation, the pavement infrastructure in the US covers a large surface area and requires intensive energy and natural resources. Vehicles that travel over these pavements are also resource intensive. Solar Roadways Incorporated envisions replacing current asphalt surfaces with modular Solar Road Panels: structurally-engineered solar panels that can be driven upon. The roadwa ...

Proposed is the development of an advanced solid state neutron spectrometer (NeuKopis) with directional resolve, building from prototype instruments that have demonstrated the art-of-the-possible. The intrinsic neutron detection efficiency of the refined

ABSTRACT: Global Engineering and Materials, Inc. (GEM) along with Columbia University propose to develop a simulation tool for modeling mixing process of multi-particle composite systems and generating the ultimate microstructure. A combined theoretical, numerical, and experimental approach will be developed to create a high fidelity software product with a reduced order modeling capability for an ...

For a vehicle in hypersonic flight, the natural transition of a boundary layer from laminar to turbulent flow depends on multiple factors including the free-stream conditions, the noise level and frequency spectrum of free-stream disturbances, the geometry of the vehicle and the vehicle surface properties.To predict boundary layer transition for flow over a given vehicle, one or more of these fact ...

ABSTRACT: Shortcomings, including high costs and lack of realism, associated with classical approaches in aircrew training have motivated the desire to develop a virtual aerial refueling training environment.Such an environment has the potential to provide a cost-effective, realistic environment to perform repetition training.A vital facet of such a training tool is the development of a realistic ...

ABSTRACT: SIFT proposes to build GEMINI (Gestalt Mixed-Initiative Intelligence), a shared workspace where humans and machines collaboratively assemble intelligence products. In a human-machine team, the collaborators have vastly different-- albeit complementary-- cognitive capabilities. Thus, a central research challenge is to expressively and soundly translate from analyst-centric interfaces (for ...
