"The U.S. military tactical vehicles currently use a ceramic tile based composite armor system in situations where a lightweight armor system is desired to provide protection against blast fragments and ballistic projectiles while maintaining adequate mobility and survivability. However, the current ceramic tile based composite armor system, which are generally manufactured using Vacuum Assisted R ...

Although advancements in CFD technology and high performance computing have proven to be effective in assessing the hydrodynamic performance of naval vessels, the effort required to develop analysis models remains challenging and time-consuming. Decomposing and manipulating design geometry for mesh construction, while capturing flow characteristics and interactions among moving components, are man ...

ABSTRACT: To complement capabilities of future autonomous systems, the Air Force requires interoperable tools & methodologies to design, verify, validate, assess & operate human-machine system interactions associated with autonomous and manned systems integration. Often the human performance measures and status of each simulation is reported independently making it challenging to analyze the data. ...

ABSTRACT: Scramjet engines are expected to operate across wide Mach number ranges and typically incorporate isolators to provide sufficient back-pressure margin and prevent unstart. Unfortunately, isolators introduce additional weight and drag, and form multiple shockwave/boundary layer interactions, which degrade the incoming flow. As military requirements become increasingly demanding, an active ...

ABSTRACT: The objective of the proposed research effort is to demonstrate the feasibility of 100 kHz to 1 MHz nonlinear spectroscopy for measurements of molecular energy distributions, energy transfer, major species, and temperature in transient combusting and nonequilibrium flows. This will be accomplished, in part, by extending burst-mode laser technology to the fs and ps regimes for greater tha ...

ABSTRACT: The goal of this proposal is to demonstrate the feasibility of a novel environmentally-compliant process to produce an advanced alloy coating(s) that imparts excellent corrosion and wear resistance to structural metals on military aircraft and weapon systems. The resulting composite coating and the coating process do not consist of any hazardous materials such as heavy metals chromium (C ...

ABSTRACT: The objective of the STTR Phase-I effort proposed by Spectral Energies LLC and The University of Tennessee is to demonstrate the feasibility of an in situ quantitative measurement of the products generated by the degradation of a material surface exposed to a hypersonic environment. The concept is based on a state-of-the-art diagnostic method: Coherent Microwave Rayleigh Scattering from ...

The objective of the work described in this proposal is to aid in the advancement of Mo-Si-B alloys for use in high temperature applications such as hot gas stream components in turbine engines. Such alloys are being characterized for their monotonic tensile properties in tension and compression as well for their creep resistance. Likewise, multiphase Mo-Si-B alloys have been studied in terms of m ...
