In Phase I, Aerius Photonics demonstrated Raman spectroscopy at 785 nm, 980 nm, and 1064 nm, with only 1064 nm-based excitation showing a reduction in fluorescence. In addition, Aerius Photonics and partner Ahura Scientific, demonstrated a breadboard version of an InGaAs-based Raman spectrometer to assess any engineering challenges. By the end of a Phase III, Aerius proposes to develop a handheld ...

By providing size resolved compositional information, the Aerosol Mass Spectrometer (AMS) has greatly advanced understanding of aircraft particulate matter (PM) emissions. AMS data have been critical to much of our understanding of aircraft PM emissions, but in the past it has had limited utility in probing the smallest (

Computational Fluid Dynamics (CFD) simulations for combustion do not currently have the predictive capability typically found for non-reacting flows due to the prohibitively high computational cost incurred when one introduces detailed chemical kinetics. In this SBIR project, we propose a novel method, Adaptive Chemistry, to enable such detailed modeling. This method adapts the reaction mechanism ...

Leveraging the Phase I achievements of the Distributed Rocket Engine Testing Health Monitoring System (DiRETHMS) including its software toolsets and system building blocks, the Phase II project seeks a comprehensive prototyping of the technology. Phase II not only expands the functionality and applications of the Phase I achievements, but utilizes evolving diagnostics due to the advanced intellige ...

Long-range optical telecommunications (LROT) impose challenging requirements on detector array sensitivity at 1064nm and arrays timing bandwidth. Large photonic arrays with integrated beam acquisition, tracking and/or communication capabilities, and smart pixel architecture should allow the implementation of more reliable and robust LROT systems. Integration of smart pixel technology for parallel ...

As an alternative material to aluminum-lithium, cryotanks developed from fiber reinforced composites can offer significant weight savings in applications for fuel containment of liquid oxygen and hydrogen. For composite materials to be accepted and utilized in these structures, they must be resistant to microcracking. It is the objective of this work to develop a matrix system for aerospace compos ...

We propose the detailed conceptual development of a device for analyzing key isotopic composition in surface materials without sample preparation. We will combine absorption spectroscopy with laser induced vaporization of solid samples for high-resolution isotopic measurements. An immediate focus is on Mars but our concept is also highly germane to other applications relevant to bio- and geochemic ...

NextGen will require the development of novel solutions to shape the airspace of tomorrow. Along with the ability to generate new systems and technologies comes the need to rigorously evaluate, and eventually validate, the effectiveness of these concepts. However, it is often challenging to translate simulation data into useful, integrated, and contextually-based assessments. Many critical finding ...

Future NASA exloration, planetary and astrophysics missions will require various enhancements in multi-stage cryocoolers. These include increased efficiency, reduced vibration and reductions in overall system mass and power consumption. For the small coolers required, pulse tube and Stirling coolers offer the best opportunities. At present, the efficiency of these coolers is limited by the effecti ...
