Acellent Technologies, Inc. proposes to develop a SMART Tape system that can be used to perform rapid non-destructive evaluation in real time and provide long-term monitoring of pressure vessels in liquid rocket engines. Based on Acellent's existing SMART Layer technology, this innovative system combines a sensor network, dedicated signal processing and data analysis software to allow for real-ti ...

Based on the success of the phase I effort, Advanced Technologies Group, Inc. proposes the development of a Cryogenic Flow Sensor (CFS) for determining mass flow of cryogens in spacecraft propellant management. Current point sensor technology is incapable of determining high pressure, high flow rate cryogenic fluid quality and mass flow rate, and has proven to be inaccurate in attempting to rapid ...

ASRI proposes to develop an advanced and commercially viable Non-Intrusive Vibration Monitoring System (NI-VMS) which can provide effective on-line/off-line engine vibration monitoring capabilities without relying on intrusive key-phasor speed measurements. Many powerful vibration signature analysis techniques for engine-health monitoring rely on key-phasor signals to extract/enhance critical fau ...

This proposal is submitted under the Innovative Tools and Techniques Supporting the Practical Uses of Earth Science Observations topic. We seek to create a prototype rangeland decision support system that links remote sensing based rangeland products, a soil biogeochemical model and web-based tools for data mining, data management and product visualization. The resulting decision support system wi ...

The use of gelled propellants for deep space planetary missions may enable adoption of high performance (Isp-vac>360 sec) propellant combinations that do not require power-intensive heating and stirring cycles before firings, and whose handling and safety characteristics are close to stated goals of "green" propellants. Phase I focused on the ability to gel both halves of the propellant combinati ...

This project will develop a much-needed multidisciplinary analysis tool for predicting the impact of aeroelastic effects on the functionality of inflatable aeroassist vehicles in both the continuum and rarefied flow regimes. In this integrated multi-physics multi-disciplinary computing environment, high-fidelity modules for continuum and rarefied aerodynamics, stress, heat transfer, and computat ...

Reliable diagnostic tools to support system health monitoring are critical both for liquid rocket experimental ground test facilities and flight systems. Here, flow induced instabilities can generate flow anomalies such as large scale pressure fluctuations that may couple with other system components and generate deleterious structural vibrations or lead to system malfunction as was evidenced in ...

Diamond Data Systems (DDS) proposes the development of a new advanced architecture, algorithms and software to support the end-to-end processing of LIDAR data to derive useful information products such as Digital Elevation Models (DEM). The approach is innovative in three ways. First, it proposes a complete end-to-end system instead of a solution that addresses only a single step of the complex ...

Advancements in nano-/micro-scale sensor fabrication and molecular recognition surfaces offer promising opportunities to develop miniaturized hybrid fiber optic and MEMS-based sensors for in situ analysis of chemicals and microbial pathogens in spacecraft air and water. Such sensors have extraordinary dual-use benefits in medical screening for early indication of certain cancers and rapid detecti ...

HyPerComp Engineering, Inc. (HEI) proposes to develop well characterized, structurally reliable filament wound composite pressure vessels for use in both cryogenic and radiation environment applications. The intent of the proposed effort is to develop the detailed pressure vessel performance characteristics that will result in "off the shelf' technology for high performance cryogenic/ radiation en ...
