ABSTRACT:A chip carrier for high power density electronics made from low CTE materials and embedded with an oscillating heat pipe will be applied to a real world satellite electronics device to transform high heat flux (e.g. 100-300W/cm2) at the device package to a lower heat flux at the heat sink areas - and do so with minimal thermal resistance. Deliverables at conclusion of two-year effort will ...

ABSTRACT: VSI proposes the development of the SIGMA (Speedy Imagery Geo-registration and Motion Analysis) system, which will address three key requirements by the end of Phase II: (i) adapt to different type of sensors, sensor-configurations and sensor operating conditions, (ii) handle large amount of data in real-time or close to real-time using limited resources, and (iii) operate under conditi ...

ABSTRACT:Innovative Technology Applications Company, LLC proposes the development of an analytical tool that predicts jet noise and engine performance for current and future generations of supersonic two- and three-stream engines. The goal is to provide robust and reliable noise predictions in minutes that can be used for design optimization. The physics-based approach will be capable of addressin ...

ABSTRACT:The proposed research effort will develop passive Oscillating Heat Pipe (OHP) structural heat spreaders to attach to small, ultra-high heat flux devices (e.g., GaN power amplifiers) and dissipate their heat loads uniformly across the spreaders' relatively large heat sinking surfaces - and do so with minimal thermal resistance. The research team will design, model, fabricate, test, and ana ...

ABSTRACT:Increasing emphasis on affordability of military systems has led to a number of advances in airframe production. For example, high speed machining (HSM) has made it possible to fabricate thin structures that provide improved performance. However, near-surface plastic strains induced by HSM or surface treatments can lead to excessive component distortion such that the component requires re ...

ABSTRACT:This Phase II project will include the research, development, implementation and deployment of a method, new image quality indicators (IQIs) and software algorithms to automatically assist in the verification of computed radiography (CR) image quality for nondestructive testing (NDT) of military airframes.Compared to existing IQIs and methods, the new approaches will more comprehensively, ...

ABSTRACT: MO-SCI Corporation and Missouri University of Science and Technology have developed and evaluated fusion welding technology applicable to ultra-high temperature ceramic (UHTC) composite joining during a Phase I ceramic joining program. This Phase II program will improve arc and reactive plasma arc welding techniques and consumables to improve joint quality. Work in the Phase I resulted ...

ABSTRACT: The objective of the Phase II effort is to extend the mathematical model investigated in the Phase I to include wind speed as well as temperature modeling, continue its development for a University of Notre Dame Wind Tunnel Facility, and demonstrate utility by adopting the model to a government facility specified by AFOSR. Specifically, the Phase II will include developmental work in ma ...

ABSTRACT: The proposal outlines work and time tables associated with finalizing the development of wear model concepts developed in Phase I work to predict the wear of two materials sliding with respect to each other while being subjected to high velocities and/or high pressures. In parallel with this, a severe wear bench test fixture design will be finalized, built, and utilized to validate the ...

ABSTRACT: Miniature flat plate oscillating heat pipe (FP-OHP) heat spreaders using ThermAvant's patent-pending ThermalCircuit architecture and low CTE materials will be demonstrated in order to transfer 100-300W/cm2 from chip-sized heaters (1cm2 to 3cm2) to a heat sink area that rejects heat at10,000W/mK. Prototypes will be modeled, designed, bu ...
