Thermal control of spacecraft is accomplished through the optical and thermal properties of the eternal surfaces of the vehicle. The use of thermal control coatings or second surface mirrors on these surfaces ar common methods for managing the overall thermal environment of spacecraft. The proposed low solar absorbance ( ) high emittance ( ET ) thermal control (TC) coating(s) shall be developed ...

High performance military aircraft operating in the hypersonic regime produce large heat loads that can only be managed with endothermic fuels. However, the current knowledge of endothermic chemistry in fuels and its effects over a range of aircraft flight conditions is extremely limited. The proposed Phase I study is aimed at the development of advanced finite rate models to characterize dehydr ...

The proposed work involves assessment of the feasibility of removal of large, concentrated heat fluxes from multi-chip circuit boards in high performance aircraft by means of liquid jet impingement cooling with subcooled change of phase. Previous studies have shown that, unlike many other types of liquid immersion concepts, the thermal performance of the proposed concept is more sensitive to coola ...

Focal plane arrays (FPAs) are one of the most critical and expensive components in infrared imaging equipment, such as nigh vision, security and surveillance systems. In the device manufacturing processes, at present, it is not possible to determine if the final product is successful until all steps and materials have been incorporated. Since this entire manufacturing process can take up to 12 w ...

As the computational power of workstations has progressed, the ability to do data fusion and visualization from a complex test has increased accordingly. However the difficulties of interfacing between a workstation and different data recording instruments still hamper their use in testing. Physitron proposes to develop an integrated test and measurement workstation for on-site data analysis and d ...

Computing and communications requirements to support modern C4I systems have undergone considerable expansion in the last decade. Requirements for C4I interoperability between the services, along with recent developments in C4I doctrine (such as C4I for the Warrior) will require far more sophisticated, more complex, and more heterogeneous computing and communications technology. Effective design a ...

BRC and its Consulting Partner Murray State University (MSU) are proposing an innovative approach to the near real-time generation of environmental effects such as dust, smoke, fog, rain and haze based upon an Auto-Regressive Moving Average (ARMA) technique that has been proven to provide realistic renderings in its simplest form. This technique creates 'Fractal-Like' complexity through the use of ...

Surface pressure fluctuations due to turbulent flow over submerged bodies can cause vibration in the surface of the body which, in turn, may radiate noise. In order to predict the structural vibrations responsible for the acoustic radiation, the wavenumber/frequency spectrum of the pressure fluctuations must be known. Experimental data and analytical methods to predict surface pressure spectra cu ...

The proposed project will develop and adapt existing state-of-the-art computational tools for accurate prediction of ejection seat aerodynamic characteristics including rocket plume effects. The resultant CFD code will be based on the solution of the full Navier-Stokes equations with advanced turbulence and combustion modeling and will utilize a rocket plume model for capturing the shape and cha ...

Recent studies by CFD Research Corporation (CFDRC) have shown that pintel, rotating sleeve/iris and butterfly variable flow control concepts offer the most promise. During Phase I CFDRC will collaborate with Atlantic Research Corporation to synergize this program with an ongoing SBIR Phase II addressing advanced solid propellant chemistry for next generation air-breathing tactical missile thrust ...
