"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 ...

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 ...

"3D-IC proposes to develop design specifications for a 12 megapixel 1000 frame / second digital output imager. The proposed design will be based on using a monolithic substrate for the photosensor array that is engineered to achieve high quantum efficiencyand good spectral response in visible light. The company proposes to investigate adaptation of its proprietary pixel-parallel processor core arc ...

"R3 Logic, Incorporated proposes to develop a high-resolution, 12M-pixel 1000 frame / s imager to meet the Army's digital imaging needs for weapons test and evaluation. Through this program, R3 Logic will not only build and demonstrate a high-resolutionimager, but will formulate a new methodology for commercially viable fabrication of large-format focal plane arrays. Large focal plane digital imag ...
