Current survivability and engineering requirements for airframe platforms necessitate the automated application of specialty coatings to the composite inlet duct OML surface. The specialty coatings have tight specification tolerances for the final thickness. Current equipment does not allow for accurate measuring of the specialty coatings. Measurement techniques and equipment need to be develop ...

Brushfire Technologies proposes to adapt our secure local area network gateway to the unique requirements of the DMO network to detect, analyze and mitigate security threats in real time with no adverse affects on network performance. Security analysis based on real time packet inspection coupled with application awareness and heuristically derived network topology information provides unpreceden ...

Combustion LES is a high fidelity CFD method that can analyze transient/acoustic challenges that previously were impossible to analyze with conventional CFD. However, excessive calculation times hinder the use of LES as an effective design tool. To make LES more practical, we propose to develop and validate a next generation combustion LES code that can solve 10M cell grids in less than one day, ...

Under AFRL Contract FA8650-05-M-5214 Phase I, CFDRC has developed and demonstrated the foundation of a comprehensive code for modeling the Cold Hearth Melting (CHM) processing of Titanium alloys. The code includes effects that accurately predict the transient temperature distribution, flow patterns, skull shape, species evaporation, and particle fates in the hearth region for a given set of dynam ...

CFDRC proposes the integration of Laser Induced Breakdown Spectroscopy (LIBS) with its maturing Laser Induced Spark (LIS) technology for rocket chamber and ultimately in-flight engine health monitoring. During Phase I CFDRC and the University of Tennessee Space Institute (UTSI) completed quantitative LIBS measurements of bi-propellant combustion equivalence ratio while simultaneously demonstrating ...

Aerospace vehicles that perform aggressive maneuvers are subject to several dynamic loads problems such as buffet and flutter. Unsteady computational aeroelastic simulations of these problems require careful attention to the physical modules of fluid and structures, as well as, to the fluid-structure interfacing and fluid-grid movement. In the Phase I study, a novel solid-brick analogy (SBA) was d ...

Run-time and convergence requirements limit practical Computational Fluid Dynamics (CFD) combustion simulations to simplified chemistry, such as multi-step global kinetic mechanisms. Current methods available for generating reduced global mechanisms are tedious, and the resultant mechanisms often lack accuracy. What is needed, and proposed for development in this SBIR effort, is a software packa ...

We propose to develop a Health and Environmental Risks Assessment Capability (HERAC) that will allow Air Force personnel and related contractors to develop actionable, scientifically based, health and environmental risks assessments of maintenance tasks upon aircraft and other weapons. Presently, no capability exists to effectively model and simulate the microscale (from 2 to 50 feet) transport an ...

Higher efficiency solar cells are needed to reduce solar-array mass, volume, and cost. In this project we propose to develop: (i) a concept of the novel quantum dot superlattice (QDS) solar cells, which are estimated to be more efficient and radiation tolerant than conventional multi-junction solar cells, (ii) new computational tools for the quantum-dot nanostructure optimization for the specific ...

Morphing technology enables aerospace vehicles to achieve a broader range of operational modes. Computational aeroelastic and design analysis tools of these vehicles must be able to handle arbitrarily large deformations and shape changes. Innovative Volume of Solid technology is proposed to cast structure/body-dynamics equations in an Eulerian reference frame, preserving the order of accuracy of ...
