The diagnostic system proposed here addresses measurement needs in a wide variety of applications in DoD facilities, national laboratories, industry, and academia. Planar measuremenets of temperature and velocity are useful in hypersonic flows, gas-turbine engines, scramjets, and pulse detonation engines, among others. Measurements of vibrational temperature are useful in non-equilibrium flows. Other applications include internal combustion engines and high-speed diesel sprays. These applications as well as follow-on work in OH PLIF, CH PLIF, acetone PLIF, and planar Doppler velocimetry are areas for significant market potential.
Potential NASA applications include measurements in ATP facilities under the auspices of the Aerothermodynamics Laboratory, such as the 31\" Mach 10 facility, the 20\" Mach 6 facility, the 15\" Mach 6 facility, and the 20\" Mach 6 CF4 facility. These facilities can utilize measurements of planar velocimetry molecular tagging velocimetry (MTV) and dual-line NO PLIF for temperature measurements. In addition, dual-line NO PLIF can be used for vibrational temperature measurements in non-equilibrium flows. The ability to track flow features at MHz rates allows detailed visualization of flow behavior, such as boundary layer separation, to aid with understanding re-entry phenomena, and for studying scramjet ignition and combustion, Finally, the Phase I will also evaluate the requirements for high frame rate (~50 kHz) imaging in high enthalpy impulse facilities, enabling ~20-30 UV or filtered Rayleigh scattering images to be obtained during single-millisecond duration \"shots.\" The ability to capture this many planar data sets in single run would greatly enhance the productivity and reduce the cost of acquiring data in such facilities.","description":"The proposed Phase I SBIR program will study the feasibility of building next-generation burst-mode laser diagnostics that will enable unparalleled planar imaging capabilities for quantitative analysis of flow parameters, such as velocity, temperature, and species concentration in large-scale hypersonic flow facilities, including short run duration \"impulse\" facilities. In particular, the instrumentation would provide the unique capability for measurements of multiple parameters at data collection rates as high as ~1 MHz with flexible wavelength and interpulse spacing for quantitative velocimetry and thermometry. During the Phase I, the proposal team will study the feasibility of developing burst-mode Nd:YAG technology with programmable temporal output while pumping a wavelength-agile UV OPO for multi-line fluorescence imaging. This requires innovation of the burst-mode pump laser to allow dual-pulse seeding, an appropriate chain of laser amplifiers, and a narrowband OPO designed for pulse-pair operation and rapid wavelength switching. Proof-of-concept demonstrations of NO molecular tagging velocimetry (MTV) and two-line NO PLIF will be accomplished in a laboratory scale high-speed flow facility (up to Mach 5). Finally, the feasibility of performing high frame rate (~50 kHz) imaging in high enthalpy impulse facilities using Rayleigh scattering will also be evaluated. This program will enable prototype development of a next generation ultra-high frame rate imaging system for high-speed flows, demonstration tests in NASA facilities, and the potential delivery of a prototype system to NASA during the Phase II.","startYear":2010,"startMonth":1,"endYear":2010,"endMonth":7,"statusDescription":"Completed","principalInvestigators":[{"contactId":506870,"canUserEdit":false,"firstName":"Sukesh","lastName":"Roy","fullName":"Sukesh Roy","fullNameInverted":"Roy, Sukesh","primaryEmail":"sukesh.roy@spectralenergies.com","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"projectManagers":[{"contactId":368183,"canUserEdit":false,"firstName":"Paul","lastName":"Danehy","fullName":"Paul M Danehy","fullNameInverted":"Danehy, Paul M","middleInitial":"M","primaryEmail":"paul.m.danehy@nasa.gov","publicEmail":true,"nacontact":false},{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[{"transitionId":66824,"projectId":8135,"transitionDate":"2010-07-01","path":"Closed Out","closeoutDocuments":[{"title":"Final Summary Chart","file":{"fileExtension":"pdf","fileId":306574,"fileName":"SBIR_2009_1_FSC_A4.01-9486","fileSize":632054,"objectId":66824,"objectType":{"lkuCodeId":1841,"code":"TRANSITION_FILES","description":"Transition Files","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"fileSizeString":"617.2 KB"},"transitionId":66824,"fileId":306574}],"infoText":"Closed out","infoTextExtra":"","dateText":"July 2010"}],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
