THE PROPOSED WORK INVOLVES APPLICATION OF SUPPORTED MOLTEN SALT CATALYSIS TO THE CATALYTIC ENDOTHERMIC DEHYDROGENATION OF HIGH ENERGY-DENSITY AVIATION FUELS. THE CATALYSTS OF INTEREST ARE HETEROGENEOUSLY DISPERSED PLATINUM AND NICKEL, TO BE USED ALONE OR IN BIMETALLIC CLUSTERS. THE MOLTEN SALTS TO BE USED INCLUDE BINARY AND TERNARY EUTECTICS INVOLVING ALKALI METAL CHLORIDES AND HYDROXIDES. THE SUP ...

"Nondestructive inspection is a key component of programs aimed at extending the service life of aging aircraft. One important capability is the detection of cracking and corrosion around fastener holes. In thick, multiple layer structures, there is oftenno solution but removal of the fasteners for inspection, a costly and potentially damaging process. Phased array ultrasonics offer a novel and ...

"Current manufacturing technology for cast titanium components cannot guarantee theabsence of hard alpha inclusions.Under the effect of fatigue, such inclusions become likely sites for structuralfailure. By performing nondestructive inspections on the manufactured parts usingphased array ultrasound, one can eliminate parts with the largest inclusions.Despite such quality control, undetected inclus ...

"A shock mitigating suspended seat which places the Special Forces Operator in an optimal ergonomic position will be developed for use in small Maritime Combatant Craft. It will feature an actively controlled shock absorber to optimize the suspension for abroad range of operator weights and sea states. In Phase I, a conceptual design of all the major components as well as the architecture for bo ...

A shock mitigating suspended seat, which places the Special Forces Operator in an optimal ergonomic position, will be developed for use in the NSW 11M RIB. It will feature a semi-actively controlled shock absorber to optimize the suspension for a broadrange of operator weights and sea states. In the Phase I effort, a conceptual design and architecture for both control hardware and software was d ...

INNOVATIVE APPROACHES ARE DESCRIBED IN THIS PROPOSAL FOR SUPPRESSING FREQUENCY MODULATION ON A SINUSOIDAL CARRIER. PARTICULAR EMPHASIS IS DIRECTED TO THE SUPPRESSION OF IDENTIFIABLE COMPONENTS OF A COMPOSITE MODULATION PROCESS FOR THE PURPOSE OF RETAINING, FOR SEPARATE MEASUREMENT, ANY FORM OF RANGE-RATE DOPPLER SHIFT/MODULATION PRESENT. THE PROPOSED EFFORT WILL CONSIST OF AN ANALYTICAL STUDY FOR ...

"The aim of our Phase II activity is to incorporate the Cohesive Volumetric Plate and Shell (Finite) Elements into LS-DYNA3D, thus enhancing its capabilities in modeling HRAM loading and damage in composite structures. In Phase I, we reported oninterlaminar failure criteria and modes, based on fracture mechanics. A damage-dependent bilinear cohesive element is used to capture the crack initiatio ...

"R3 Logic, Incorporated proposes to perform a comprehensive study to develop a fullsuite of computer-aided design tools for three-dimensional circuit integration. Thecompany will build on its existing tool set that enables 3-D physical layout andverification and will develop recommendations for extending these tools to permitanalyses of 3-D circuit performance, including thermal and electromagneti ...

R3 Logic proposes to develop an openly accessible Design Environment that will incorporate CAD tools needed for the analysis and design of 3D integrated circuits, including schematic capture, VHDL interfaces, 3D physical layout, verification, 3D parasiticextraction, interactive coupled electro-thermal simulations, and thermally-aware place and route methods. We will achieve this goal, first by bui ...
