In Phase 1, Intelligent Fiber Optic Systems Corporation (IFOS), in collaboration with North Carolina State University, successfully demonstrated a Fiber Bragg Grating (FBG)-based system for simultaneous, continuous, multipoint temperature measurements at different depths in a representative Thermal Protection System (TPS) material (Super Lightweight Ablator?SLA), with testing performed near its ch ...

In this STTR effort, Los Gatos Research (LGR) and the University of Wisconsin (UW) propose to develop a highly-accurate sensor for high-purity oxygen determination. The analyzer, which is based on LGR's patented Off-Axis ICOS technique, will be capable of rapidly quantifying high-purity oxygen (95 – 100 %) with very high accuracy (better than ? 0.03 %), minimal calibration, and no zero drift. M ...

Aircraft Flight Operations Quality Assurance (FOQA) programs are implemented by most of the aircraft operators. Vast amounts of FOQA data are distributed between many computers, organizations, and geographic locations. This project develops methodology for transforming such distributed data into actionable knowledge in application to aircraft health management from the vehicle level to the fleet l ...

NASA is developing algorithms and methodologies for efficient air-traffic management. Several researchers have adopted an optimization framework for solving problems such as flight scheduling, route assignment, flight rerouting, nationwide traffic flow management (TFM) and dynamic airspace configuration. Computational complexity of these problems have led investigators to conclude that in many ins ...

We propose to design a low noise, two-side buttable, 64x64 readout multiplexer with the following key design features:1- By far the largest readout array developed for far IR detectors to date. Four of these readout can be butted together to form a>16k-pixel mosaic array satisfying the need of the next generation of astronomical instruments.2- Optimized for use with far infrared detectors requiri ...

Los Gatos Research (LGR) proposes to develop highly-accurate, lightweight, low-power gas analyzers for measurements of carbon dioxide (CO2) and water vapor (H2O) aboard NASAs Sensor Integrated Environmental Remote Research Aircraft (SIERRA) unmanned aerial system (UAS). These analyzers, which will exploit both conventional mid and near-infrared tunable diode laser spectrometry and LGR's patented O ...

a. Paragon Space Development Corporation¿ (Paragon) proposes to continue our investigation into the use of microporous-ionomer membrane technology to improve the robustness and effectiveness and simplify water recovery processes for space applications. Improved robustness and effectiveness will be evident through (1) reduced loading onthe downstream post processor due to the ionomer¿s unique pr ...

The goal of this program is to develop a miniaturized and in-situ operated gas microsensor array for the real time monitoring of chemical composition of turbine engine combustors and/or exhaust streams to improve NASA's aeronautical flight test capabilities. Phase II will develop a high temperature microsensor array suitable for incorporation in engines, as installed in aircraft. Sensor arrays d ...

Toyon Research Corporation proposes to develop and demonstrate a prototype low-cost precision navigation system using commercial-grade gyroscopes and accelerometers. During the Phase I effort an uncalibrated brassboard system was built and flight tested using a manned biplane. The brassboard system comprised an experimental single-channel (L1-only) software GPS receiver, and a 720 deg/hr inertial ...

Gas turbine engine technology is constantly challenged to operate at higher combustor outlet temperatures. In a modern gas turbine engine, these temperatures can exceed the blade and disk material limits by 600 ¿F or more, necessitating both internal and film cooling schemes in addition to the use of thermal barrier coatings. Internal convective cooling is inadequate in many blade locations, and ...
