This is a broad area including rocket plumes, reaction control systems, inlet flows, nozzle and exhaust flows, combustion, distributed electric propulsion, hypersonic propulsion flow, and tightly integrated/coupled propulsion systems.","exampleTechnologies":"Technology challenges include prediction and characterization of flow-related performance for integrated propulsion systems. Applications include distributed electronic propulsion, propulsion integration for sustained hypersonic flight, highly integrated efficient propulsion systems for aviation, Reaction Control Systems (RCS) during spacecraft entry, supersonic retro propulsion, launch abort vehicles, launch vehicle ascent, and stage separation.","hasChildren":false,"hasInteriorContent":true}],"startTrl":3,"currentTrl":4,"endTrl":4,"benefits":"This technology supports NASA's mission to help improve the performance of commercial aviation through development of advanced gas turbine engine systems. The technology also has the potential for enabling improved gas turbine engine performance for applications as far-reaching as Unmanned Aerial Vehicles (UAVs) proposed for extraterrestrial exploration. An efficient DBD actuator system can provide active stall control for compressor blading and low-pressure turbine blades. Implementation of a practical DBD actuator system, including the necessary driving and control electronics, should allow significantly improved low mass flow operation of turbine engines, as well as greatly increased operational envelopes.
In addition to military and NASA customers, a fully developed active flow control technology for turbomachinery may also prove useful in commercial applications in which separation phenomena are known to cause performance issues, including turbine engines (for both power generation and aircraft use) and aerial vehicles. The implementation of an effective and efficient compressor stall control system can greatly improve the operational envelopes for both existing retrofitted compressors, as well as enable new compressor designs with significantly lower stall limits.","description":"Modern aircraft gas turbine engines utilize highly loaded airfoils in both the compressor and turbine to maximize performance while minimizing weight, cost, and complexity. However, high airfoil loading increases the likelihood of flow separation at lower mass flow rates. Dielectric Barrier Discharge (DBD) plasma actuators have been shown to be a very promising technique for compressor stall control. DBD devices can either be installed directly on rotor/stator surfaces or the compressor end walls to control rotor tip flow. A fundamental challenge in driving DBD actuators is providing appropriate electrical waveforms to the devices. Creare proposes the development of an innovative DBD actuator charging circuit topology which enables (1) low voltage DC power distribution, (2) a modular approach to achieving total power delivery, (3) use of commercial-off-the-shelf (COTS) components, and (4) resolution of impedance matching issues associated with other DBD charging circuit topologies.","startYear":2013,"startMonth":5,"endYear":2013,"endMonth":11,"statusDescription":"Completed","principalInvestigators":[{"contactId":392488,"canUserEdit":false,"firstName":"Richard","lastName":"Kaszeta","fullName":"Richard W Kaszeta","fullNameInverted":"Kaszeta, Richard W","middleInitial":"W","primaryEmail":"rwk@creare.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":3164174,"canUserEdit":false,"firstName":"DAVID","lastName":"ASHPIS","fullName":"David Ashpis","fullNameInverted":"ASHPIS, David","primaryEmail":"ashpis@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":[{"caption":"A Novel Plasma-Based Compressor Stall Control System","file":{"fileExtension":"jpg","fileId":299602,"fileName":"SBIR_2012_1_BC_A3.08-9070","fileSize":43059,"objectId":296140,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"42.0 KB"},"files":[{"fileExtension":"jpg","fileId":299602,"fileName":"SBIR_2012_1_BC_A3.08-9070","fileSize":43059,"objectId":296140,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"42.0 KB"}],"id":296140,"title":"Project Image","description":"A Novel Plasma-Based Compressor Stall Control System","libraryItemTypeId":1095,"projectId":16565,"primary":true,"publishedDateString":"","contentType":{"lkuCodeId":1095,"code":"IMAGE","description":"Image","lkuCodeTypeId":341,"lkuCodeType":{"codeType":"LIBRARY_ITEM_TYPE","description":"Library Item Type"}}}],"transitions":[{"transitionId":68835,"projectId":16565,"transitionDate":"2013-11-01","path":"Closed Out","closeoutDocuments":[{"title":"Final Summary Chart","file":{"fileExtension":"pdf","fileId":307697,"fileName":"SBIR_2012_1_FSC_A3.08-9070","fileSize":224228,"objectId":68835,"objectType":{"lkuCodeId":1841,"code":"TRANSITION_FILES","description":"Transition Files","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"fileSizeString":"219.0 KB"},"transitionId":68835,"fileId":307697}],"infoText":"Closed out","infoTextExtra":"","dateText":"November 2013"},{"transitionId":68836,"projectId":16565,"partner":"Other","transitionDate":"2014-05-01","path":"Advanced To","relatedProjectId":18008,"relatedProject":{"acronym":"","projectId":18008,"title":"A Novel Plasma-Based Compressor Stall Control System","startTrl":3,"currentTrl":4,"endTrl":4,"benefits":"This technology supports NASA's mission to help improve the performance of commercial aviation through development of advanced gas turbine engine systems.

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.
