Sponsored by NAVAIR, Accudyne Systems completed a Phase 1 SBIR program, developing an equipment and process concept for cost-effective fabrication of composite rotary wing main rotor blade spars. The CH-53K spar was the study focus. The recommended work cell concept combines automated tape placement, woven fabric placement, and pick and place of 45° parallelograms to layup plies, then debulk and ...

We propose to develop and deliver a nano-patterned metallic light trap platform that will allow ultra-thin InGaN photovoltaics to exhibit extended lifetime by a factor of four when used in low orbit satellite operations. We will test the enhancement of light absorption in InGaN layers with In fraction of 25% for use as an effective method of realizing radiation ultra-hard solar cells for space-ba ...

Commodity graphics processing units (GPUs) offer tremendous computational throughput for relatively little cost. They have been shown to outperform microprocessors in the important metrics of FLOPS/dollar, FLOPS/Watt, and FLOPS/unit space and have already been applied to a wide range of numerically intense problems. In Phase I of this project, we demonstrated their potential to enhance complex C ...

This SBIR Phase II proposal develops an innovative PTIR adhesive and process for bonding stud fasteners to composite surfaces in aircraft manufacturing and repair. The PTIR adhesive formulation has a low concentration of infrared emitter/absorber dispersed in a thermoset epoxy adhesive paste. The PTIR adhesive paste is applied to the base of a stud fastener and the stud is irradiated using a P-Wav ...

In phase I, we have proven the feasibility of using the microwave cavity perturbation technique to detect and quantify DoS in marine aluminum alloys. We implemented an alpha version sensor prototype, characterized and validated its performance using ASTM G67 method. We also identified methods to further enhance the sensor sensitivity, so that DoS in the low (a few mg/cm2) to moderate range can be ...

The state-of-the-art FPA manufacturing technologies commonly generate some critical defects in the pixel elements, which adversely impact their operability and reliability. In Phase I, the feasibility of identifying, analyzing, and on exemplary basis, eliminating these defects indirectly through nanostructural analysis was demonstrated. In Phase II, this defect analysis and correlation approach ...

Scientific Monitoring Inc. (SMI), in partnership with GE Aviation (GE), proposes to develop a set of maintenance support tools for automated analysis of reliability data. These tools can extract data from a military data warehouse (MDW), analyze the data, update models, flag failure trends, and recommend proper actions to maintainers and designers/ engineers. This toolset will use existing measure ...

A versatile and portable instrument for stray light detection and diagnosis at both visible and infrared wavelengths will be designed, built, and demonstrated. The core idea of the proposed approach is to use subaperture, rather than full aperture, illumination for stray light detection. The subaperture approach uses a scanning pencil beam (SPB) that provides information about the location of a s ...

Traumatic Brain Injury (TBI) is a leading source of morbidity in U.S. soldiers in Iraq. Each year 1.5 million Americans sustain a TBI and there are 5.3 million people with a permanent TBI-related disability in the U.S. Videogames have been shown to increase TBI patient cognitive ability, memory and recall. The purpose of this proposal is to meld clinical strategies used in treating TBI patients ...

An expedited and economical nanostructural sampling and analysis of semiconductor devices will be crucial to accelerated product development and rapid introduction of these technologies to the market with a higher quality at a lower cost. The proposed effort aims to carry out the next phase of development activities, geared toward realization of the above objective. We successfully demonstrated ...
