Adaptive Filtering for Aeroservoelastic Response Suppression, Phase I

CSA Engineering proposes the design of an adaptive aeroelastic mode suppression for advanced fly-by-wire aircraft, which will partition the modal suppression function from the rigid-body Flight Control System (FCS). CSA is recognized as having world-class expertise in the areas structural dynamics, vibration control, and control-structure interaction. Phase 1 will leverage expertise in structural dynamics and system-identification to develop adaptive filtering algorithms which operate in both the spatial and time domains to identify/estimate key aeroelastic generalized (modal) DOF and suppress aeroservoelastic interactions while minimizing the degradation of phase margin with respect to the FCS. During Phase 1, CSA will develop an end-to-end aeroelastic aircraft dynamic model of appropriate complexity as well as related sensors and measurement systems which will support the adaptive mode suppression effort. Sensors and measurement systems will be evaluated concurrently with adaptive filtering algorithms with regard to convergence, stability, and robustness. Filter architecture parameterization and constraints will be investigated. The goal of this development is to partition the suppression of aeroservoelastic interactions separate from the rigid body FCS, enabling FCS design and configuration/adaptation to be independent of aeroservoelastic considerations.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
