To allow aviation growth to continue in the face of increasingly stringent noise pollution standards, new aircraft engines must be designed with noise performance as a principal constraint. Technologies to realize future propulsion noise reduction will require detailed experimental characterization and diagnosis of the acoustic mechanisms and sources within an engine system or component. ATA Engin ...

Unmanned Air Systems (UAS) are no longer coming, they are here, and operators from first responders to commercial operators are demanding access to the National Airspace System (NAS) for a wide variety of missions. This includes a proliferation of small UAS that will operate beyond line of sight at altitudes of 500 ft and below. Currently the UAS arena includes traditional airframers, established ...

Modern high efficiency gas turbine engines typically operate with hot section temperatures so high that metal parts in those areas need to be cooled to maintain strength and life properties. A well-established approach to this bleeds a portion of the compressor discharge air to flow through and over turbine parts. As engine compressor pressure ratios continue to increase, the temperature of this c ...

Dryden (Armstrong) Flight Research Center has developed a 4-fiber interrogation system for Fiber Optic Smart Structures (FOSS) sensor networks interrogation. Replacing the expensive, bulky, mechanically tuned swept laser technology used in the FOS system will help reduce the system cost, size and weight, and enable massive deployment. In this program, Freedom Photonics proposes to develop a novel, ...

Makel Engineering Inc. (MEI) is developing flight capable chemical microsensor arrays for in situ monitoring of high temperature bleed air and turbine exhaust in jet engines. The proposed chemical sensor probes will be a new class of onboard engine instrumentation for real time monitoring engine and bleed air system operation in flight. Sensor arrays developed by MEI have been demonstrated for gro ...

Eotron has introduced an improved illumination source for 3D IR Laser Time-of-Flight (ToF) systems based on its patented 3D silicon technology originally developed to improve efficiency and power of solid state lasers. Using proprietary design, fabrication and thermal management techniques, Eotron developed a highly efficient and compact silicon package / assembly for both IR VCSEL and Laser Diod ...

This Phase II proposal presents a scope of work to develop reliable Sense and Avoid for BVLOS Unmanned Aerial Vehicle [UAV] operations. We first analyze a) the requirement for avoidance based on the UAV's ability to get away from danger and b) the suite of candidate technologies needed to detect intruders with ample time to get away. To meet this need we will build a reliable FINE TRACKING sen ...

Opus 12 has redesigned the cathode of the commercially available PEM water electrolyzer such that it can support the reduction of carbon dioxide into ethylene and/or methane and suppress the competing hydrogen reaction. Methane and ethylene are well known polymer precursors that can be used as starting material to make plastics in extraterrestrial environments. PEM water electrolyzers have alread ...

A technique for measuring velocity in rocket plumes called hydroxyl tagging velocimetry (HTV), which was developed previously and demonstrated on a small rocket engine, is proposed for use on a full scale engine. Specific goals of the program include producing a measurement system that can withstand the high acoustic levels of a relevant full scale rocket engine, development of efficient user-frie ...

The creation of a five-dimensional task analysis visualization (5D-TAV) software tool for Task Analysis and Workload Planning using multi-dimensional visualization will have significant positive impacts on the optimization of human-centered design at NASA. Recent research identified a 40% improvement in task analysis accuracy and efficiency using 3D visualization. Employing enterprise data managem ...
