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}],"description":"Enabling a new generation of high-speed civil aircraft will require breakthrough developments in propulsion systems, including novel techniques to optimize inlet performance in multiple operating conditions. Maximizing propulsive performance while minimizing weight and mechanical complexity is a key goal, and rapidly maturing smart materials technology can enable adaptive control of inlet geometry to allow in-flight optimization of engine flows. Phase I of this effort built on established device technology using high strength Shape Memory Alloy (SMA) actuators and initiated development of adaptive inlet concepts for application to Supersonic Business Jets (SSBJs). Leveraging this work as well as prior efforts in SMA device design and testing has permitted the first steps in the development a family of actuation and flow control devices for use in flight applications. Phase II will build on this work with mutually supporting design, analysis, and test activities including: detailed definition of the effectiveness of geometry adaptation in improving installed engine performance at low and high speeds; construction and test of a benchtop adaptive inlet component demonstrator using high temperature SMA alloy actuators; high-speed wind tunnel testing of sectional components with realistic thermal and aerodynamic loads; and construction of a model 3D adaptive inlet.

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.
