Space platforms are complex dynamical systems and there are many reasons to model them from ground telescope imagery as well as from space-based sensor platforms. One key motivation is to determine the operational state and configuration of the vehicle. Key questions such as did the solar panels fail to deploy, did the object begin to tumble unexpectedly may be addressed by a sufficiently detaile ...

The design and development of a number of advanced Air Force propulsion systems is substantially limited by the current inability of computational design support tools to adequately and cost-effectively predict the complex flow physics and combustion dynamics that governs system performance and stability. The innovation proposed consists of a comprehensive experimental-modeling framework to (i) sy ...

The goal of this Phase II effort is to achieve significant improvements in our understanding and modeling of trans-critical combustors operating at high pressure in regimes of interest to the Air Force.There are three main objectives we pursue:1) The use ofmolecular dynamic models as a predictive tool for thermodynamic and transport properties of mixtures, 2) Improved liquid/gas interface models a ...

This Phase II STTR effort is focused on generating the data necessary to identify the phenomenology that produces carbon deposition within kerosene film cooled rocket engines.This data is essential to guide the model development and validation process.Program outputs will be both data and a physics-based model for carbon deposition.

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 ...
