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: 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: 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: Sierra Engineering Inc. (Sierra) believes that existing chemical kinetic models can be efficiently incorporated into commercial CFD codes to predict the mixing, pyrolysis, soot formation and carbon deposition within film cooled rocket engines. During this Phase I STTR effort we will demonstrate that this analysis capability is practical and that we can generate appropriate model validati ...

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 ...

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: 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 ...

The development of a high fidelity, generalized computational framework with the necessary physical submodels incorporated for the analysis of multiphase, combusting, internal and external ballistic flows is proposed. The focus in Phase I will be developing a framework based on an existing unstructured multi-element, fully implicit, CFD code to provide an end-to-end analysis capability for interna ...

A hybrid lithium ion battery / super capacitor energy storage device is developed that uses the high power capability of the super capacitor to satisfy pulsed power load requirements such that stress on the lithium ion batteries is reduced. This results in extended discharge time and higher efficiency utilization of the battery stack.

ABSTRACT: The goal of the Phase I effort is to develop a detailed and comprehensive plan that identifies specific, tangible improvements to improve the fidelity of modeling trans-critical combustors. Both hydrogen/oxygen as well as hydrocarbon (RP-1, RP-2) / oxygen systems will be considered. The focus will be on developing improved modules for equations of state for trans-critical mixtures, as ...
