AEDC personnel have developed and demonstrated the effectiveness of coupling a control volume model with a wind tunnel control system. The performance of the model was hampered because parameters of the model were assumed to be constant, when they are likely variables. A method for using facility data to determine functional relationships defining these parameters would allow them to vary during ...

In this STTR Phase I project, CFD Research Corporation and University of Nebraska at Omaha will develop a preliminary computationally-driven first-principles framework for discovery and design of non-RE-containing alloys for high temperature applications. While rare-earth (RE) based alloys have played a pivotal role in modern defense and high-tech industry, sustainability of RE-based materials is ...

The objective of the proposed Phase-I effort by Spectral Energies LLC is to design and develop a fiber-coupled hyperspectral LWIR thermal imaging sensor suite for temperature measurements in practical combustors. The proposed sensor suite will be capable of performing spectrally resolved imaging to achieve accurate temperature measurements in practical gas-turbine engines while resolving optical i ...

Two-dimensional (2D) visualization techniques have limit capacity to achieve understanding of full dimensionality of the battlefield. Rewritable 3D holographic storage is promising for updatable 3D display applications. In Phase I, New Span Opto-Technology has demonstrated novel concepts of both holographic recording technique and recording material system without the use of high voltage. We have ...

Accurate knowledge of heat flux is critical in assessing the performance and survivability of hypersonic aerodynamic systems. Under these flow regimes extreme pressures, temperatures, and vibrations make it difficult to quantify even the most basic aerothermodynamic properties. Ahmic Aerospace and Virginia Tech propose an innovative new approach to develop robust heat flux sensors and a data reduc ...

The proliferation of commercial, visible and infrared wavelength laser systems is increasingly becoming an existential threat to our warfighters, which drives the need for further EO/IR sensor and eye protection development. Current fielded sensor protection is limited to fixed wavelength filters. Broadband filters designed to circumvent multi-wavelength laser threats are plagued by low transmitta ...

High Velocity Penetrator Weapons experience severe stress in terms of high frequency vibration and shock during launch, flight, and on impact. The extreme conditions have significant impact on the survivability of the weapon due to damage of the energetic material and fuze compartment. Molecular dynamics is often used to understand the effect of external shock on the material. However, molecular ...

ABSTRACT: The objective of this effort is to develop innovative methods for deriving a sparse set of physical target features that can be used for exploitation of air to ground signature data collected from sensor systems including electro-optical, infrared, and laser radar. Current classification methods require near exact replication of the original imaging parameters, or extensive modeling in ...

The objectives of this research effort are to experimentally derive the scaling laws up to 30 bar for key combustion species and temperature for reactions involving various hydrocarbon fuels in such a way so that the spatio-temporally resolved measurements would not be influenced by signal-degrading processes such as quenching, photolytic interference, Stark shift, and stimulated Raman. This build ...
