Damage Adaptation Using Integrated Structural, Propulsion, and Aerodynamic Control, Phase II
Completed
Description
Over the past decade, researchers have been making great strides in the development of algorithms that detect and compensate for damaged aircraft. Before these algorithms can be used in civil aviation, progress is needed to (a) ensure that these innovative and frequently non-deterministic algorithms will always perform as expected and (b) address challenges associated with integrating these algorithms into an overall avionics system. The authors addressed the second challenge by developing an integration approach called Operational Envelope Safety Assurance (OESA). In Phase I, the authors showed that OESA can integrate control, path planning, diagnostics, and structural health monitoring algorithms in a way that ensures the subsystems will never issue commands that put the aircraft outside its safe-operating envelope. In Phase II, the authors will formalize the approach, develop a general set of OESA subsystem specifications, and demonstrate safe integration of algorithms developed by other researchers under related research efforts. Phase II will culminate in real-time high-fidelity demonstrations of an integrated controller for a NASA testbed (either the Langley AirSTAR GTM or the Dryden A-53 F-18 testbed) and will set the stage for Phase III flight tests.

How to get involved
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.
