AbstractEnabling a new generation of high speed civil aircraft will require breakthrough developments in propulsion design, including novel techniques to optimize inlet performance across a wide speed range. Maximizing propulsive performance while minimizing weight and mechanical complexity is a key goal for such systems, and rapidly maturing smart materials technology can enable adaptive control of inlet geometry to allow in-flight optimization of engine flows. This proposal will build on established device technology using high strength Shape Memory Alloy (SMA) actuators and will initiate development of adaptive inlets for high speed applications. Leveraging prior work in design and testing of SMA devices in challenging aerospace and marine applications will allow a jump start in development a family of actuation and flow control devices suitable for use in practical flight applications. Actuation systems employing a combination of high temperature SMA alloys and active heat control systems will be developed, along with complementary analysis and design tools for aero/thermo analysis of integrated actuators. The modeling and benchtop testing work proposed for Phase I will lay the groundwork for testing in representative high speed conditions in Phase II.
