Expected Technology Readiness Level (TRL) upon completion of
contract:
TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200
words) We propose to design, build and evaluate a prototype of a
compact, robust, optically-based sensor for making temperature and
multi-species concentration measurements in propulsion system ground and
flight test environments. This system will utilize a widely tunable near
infrared light source to make absorption measurements of combustion
reactant and products in the combustion zone (with accuracy from 100-1000
ppm). Although possible to tune over a very wide wavelength range, during
phase-II we propose to develop the light source which will be able to
continuously tune from 1.4 to 1.8 microns while maintaining a narrow
bandwidth of 0.01 cm-1 using a novel combination of acousto- and
electro-optically controlled devices. The rapid tunability of this light
source will obviate the need for dense multiplexing of multiple
wavelengths as signals can be multiplexed in time while maintaining fast
temporal response. Furthermore, the wide spectral bandwidth allows for the
selection of the optimum absorption transitions, without regard for the
commercial availability of narrow bandwidth diode lasers. The proposed
instrumentation will be environmentally rugged, with the ability to
withstand extreme ranges of temperature, humidity, vibration and shock
conditions. Further, the system will possess auto-calibration
capabilities, fast response time (few microseconds) and can be battery
operated.
POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters,
approximately 150 words) There are many commercial and military
applications for an accurate and rugged laser absorption system capable of
acting as a temperature and/or concentration sensor. The sensor could be
used in both new and retrofit commercial aircraft as a control sensor for
propulsion systems, as its capabilities easily extend to a very wide-range
pressure environment. The reliable and precise instrument can be used to
control gas turbine combustors, afterburners, and turbine optimization.
The system could also be used in aircraft fuel tanks to measure fuel vapor
flammability and oxygen concentration in OBIGGS systems. Furthermore, due
to the widely tunable light source, this sensor could be used to replace
TDLAS sensors in any application, as there is a demonstrable advantage in
system cost, complexity, and operation.
POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500
characters, approximately 150 words) This type of sensor can also be
used to monitor the combustion efficiency in terrestrial gas turbine and
high-pressure combustion systems where a rugged sensor with long operating
life characteristics is needed. Also it is possible to use this sensor for
real-time biological measurements as the system can also be used as a
Fraunhofer Line Discriminator Spectrometer for sub-angstrom remote sensing
of fluorescence emission in the Fraunhofer line wavelengths. Finally,
large and complex molecules that have extremely broad absorption
signatures could be fully resolved with this sensor, with application to
national security sensing of weapons and explosives.
NASA's technology taxonomy has been developed by the SBIR-STTR program
to disseminate awareness of proposed and awarded R/R&D in the agency.
It is a listing of over 100 technologies, sorted into broad categories, of
interest to NASA.
