ABSTRACT:A joint experimental and computational project using a carefully designed, flexible test article is proposed to assess the velocity-coupled combustion response of a representative liquid rocket injector element to transverse acoustic disturbances. In the proposed Phase II, the response of an injector flowfield at supercritical pressure conditions will be simulated, measured, and reduced i ...

ABSTRACT: Stainless steel ballscrew components, such as those found in landing gear and flap actuators on the C-130 aircraft, experience wear and subsequent failure due to corrosion, contamination and foreign object damage (FOD). High"dither"conditions, where the actuator undergoes a constant short-travel, high-frequency movement to maintain level flight, can also induce wear on actuator ballscr ...

ABSTRACT: The thermal spray process has many inherent complexities within each sub-process including feedstock manufacturing, component surface preparation and masking, torch parameter selection, robot trajectory and laboratory coating evaluation. Each sub-process is governed by rigid specifications that provide thermal spray applicators with procedural and process guidelines throughout the appl ...

ABSTRACT: A challenge which continues to present a barrier to the utilization of AM and wide spread adoption is knowing when to use the technology. This is particularly problematic in aerospace and in MRO operations because the technology is still emerging, and knowledgeable, experienced practitioners remain in short supply and will likely remain so until the next generation of technicians and en ...

ABSTRACT: This document presents Optical Sciences Corporation's SBIR technology transition proposal to complete development of an advanced Cryogenic-Vacuum Compatible Infrared Scene Projector (CVC IRSP) for Wide Field-of-View (WFOV) space sensor testing and to integrate the CVC IRSP into a government owned space simulation chamber. The CVC IRSP will be capable of projecting complex scenes w ...

ABSTRACT: Assured Information Security, Inc. (AIS) proposes Endpoint-Operated Link-assured Security (EOLuS), an effort to develop a product with the capability for realizing continuous end-to-end trust (EtET) in a dynamic network a network in which every client would verify and monitor the trustworthiness of its peers prior to communicating sensitive information. After the successful completion ...

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 ...

Raman spectroscopy is a non-destructive optical technique for detecting molecules on a sample surface, and it is well-suited for the quantification of organic molecules within a mixture. Convenient hand-held Raman spectroscopes are currently manufactured by Ocean Optics, a recognized world leader in the manufacture of miniaturized spectrometers, and we propose to customize one for specific use by ...

ABSTRACT:The overall goal is to develop an evaluation systembased on real Mission dataof Ground Moving Target Indicator (GMTI) exploitation algorithms.Real-world Mission data is identified by analysts, who in the standard course of doing their job, fulfill Request for Information (RFI) Essential Elements of Information (EEI) responses.Our objectives are to provide the capability to evaluate a wide ...

ABSTRACT: In order to prevent loss of sensitive data, organizations need to be able to tag data with classification and releasability metadata. Currently classification is a manual and labor-intensive process, which slows the dissemination of sharable data. ATC-NY will develop DocMark, a product to automatically determine classification and dissemination metadata and record it in standard forma ...
