ABSTRACT: The innovation proposed is a computationally-tractable, physics-based, portable turbulent combustion modeling strategy for application to a wide range of Air Force aero-propulsive systems, including augmentors, liquid rockets and scramjets. This modeling strategy will be implemented within an Application Programming Interface (API) library suitable for easy integration within Air Force ...

ABSTRACT: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...

ABSTRACT: Coordinating and sharing information across multi-level security (MLS) networks are of great interest in many military applications. However, it is very challenging to accomplish those goals due to the heterogeneous security classifications of different network domains. The recent proposed cross-domain solutions (CDS) provide initial steps to make such applications possible. However, th ...

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 ...
