These systems include both mechanical and propulsive systems.","exampleTechnologies":"For launch vehicles: Thrust vector control (TVC), main propulsion systems, reaction control systems (RCS), roll control systems (RoCS), separation motors, ullage settling motors, abort propulsion systems, propellant storage and transfer, nanocomposites, green propellants. For in-space propulsion: CubeSat propulsion, propellant management devices (PMDs), pressure regulation mechanisms, propellant thermal control systems, propellant vapor control systems, long-duration propellant-compatible materials, high-performance main engines, low-impulse attitude-control systems, propellant slosh control, deep-throttling precision lander engines","hasChildren":false,"hasInteriorContent":true}],"description":"Active Signal Technologies and its subcontractor Moog propose to develop a high-frequency actuator driven valve intended to achieve TRL 6 by the end of Phase II. This active control component will be capable of modulating fuel flow at multiple injection locations with minimum fuel pressure drop and thus enable critical improvements in aerospace vehicle turbine engine combustion dynamics, notably mitigation of thermo-acoustic instabilities. These instabilities have impeded development of advanced lean-burning combustors for reduction of NOx emissions and improvements in combustion efficiency. While passive approaches to control combustion instability have been successful on particular new engine designs, the ultimate solution is active combustion control where the greatest challenges are the bandwidth (1 kHz) and system temperature requirements. The Phase-I goal is to demonstrate that these are achievable by designing and building a proof-of-principle system complete with high-frequency, high-temperature actuator and valve. Active Signal has selected Terfenol as the most suitable actuator material and will apply 25 plus years of actuator, valve and pump experience to meet the goals. The system will be tested against pressure and flow requirements to demonstrate the effectiveness of this approach before fabricating a prototype suitable for the GRC test stand in Phase II.","startYear":2009,"startMonth":1,"endYear":2009,"endMonth":7,"statusDescription":"Completed","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}],"website":"","libraryItems":[],"transitions":[],"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.
