ABSTRACT: Remarkable advances in artificial intelligence (AI) and human-systems integration are providing aircrew with cockpit automation systems of unprecedented sophistication. Onboard intelligent assistants monitor the aircraft, interpret and carry out pilot commands, and advise the pilot (onboard or remote) as to aircraft and system status, mission progress, threats and alerts. Because pilots ...

ABSTRACT: The proposed VPHS (Vision Processor for Helmet Systems) is an advanced technology image processing engine that is designed to provide the image processing requirements of helmet mounted imagery systems. The VPHS will input high resolution image data from imaging sensors, process that data to yield enhanced visualization and output the imagery to operator displays. The VPHS will employ im ...

ABSTRACT: This Phase I effort will identify and evaluate candidate materials to replace existing beryllium-copper alloy components for use in aerospace ground test flow facilities. The candidate materials must offer similar or better performance metrics (dimensional stability, lifetime, etc.), be domestically and readily available, offer similar or cheaper costs, and the ability to withstand temp ...

ABSTRACT: Methodology for prediction of soot build-up in liquid film-cooled rocket engines will be incorporated into the CRUNCH CFD code, using a reduced-mechanism pyrolysis model and soot formation model developed at University of Virginia. A companion experimental program will be conducted at University of Virginia to collect data for calibration of the pyrolysis models for conditions and fuels ...

ABSTRACT: Present CALPHAD software tools do not address data heterogeneity and fragmentation challenges in a way conducive to the feasible development and maintenance of high-quality databases of more than, perhaps, 5 or 6 components, yet alloy systems of commercial interest can easily reach 12-15 components. We propose to use a newly developed thermodynamic software engine and new algorithms to d ...

ABSTRACT: The proposed program is a joint effort between General Sciences, Inc. (GSI) and Drexel University. The proposed concept for Plasma Generation is based on the use of highly exothermic condensed phase reactions yielding temperatures considerably higher than the boiling points of candidate metal elements with residual energy to maximize their vapor yield and, with high probability to enter ...

We propose a comprehensive software tool called ModelTime(TM)for the design, analysis and construction of multi-core software for distributed real-time systems using a model-based design methodology. ModelTime will use UML-like diagrams to capture networked multi-core platforms, software components and configurations, functional and para-functional attributes like end-to-end timing constraints, a ...

Overwhelming heat and clocking considerations have led to the accelerating rise of multicore processors. The number of cores per chip is expected to increase rapidly in coming years. In fact, chips with 100 cores and prototypes with 128 cores are already available. As the number of cores increases, the scalability of the operating system(s) will become a major bottleneck, particularly for embedd ...

ABSTRACT: Future hypersonic vehicles, like X-43 and X-51 derivatives and Falcon HTV-3, will require advanced strategies for thermal protection systems (TPS) and methods of structural integration. The goal in designing TPS for these types of high performance applications is to establish multi-mission reusable systems with reduced weight and increased performance that possess multifunctionality, e ...

ABSTRACT: To unlock the power of cooperating teams of autonomous cyber-physical systems (CPSs), humans must be able to effectively, reliably, and safely task them using high-level goals. SIFTs Playbook interface approach provides goal-based tasking for multi-agent autonomous missions. SIFTs Cooperative Intelligent Real-time Control Architecture (CIRCA) automatically synthesizes and verifies r ...
