Integrated Reconfigurable Aero and Propulsion Control for Improved Flight Safety of Commercial Aircraft, Phase I
Completed
Description
The main objective of this project is to develop and test a novel innovative Integrated Reconfigurable Aero & Propulsion Control (IRAP) system that achieves flight safety improvement in commercial aircraft. The main feature of the proposed IRAP system is that it is well suited for uncertain plants containing actuators operating on different time scales. The focus under this project is on the flight control system design for aircraft with fast actuators moving the flight control surfaces, and engines characterized by a slower response. The IRAP system will be developed for operation under faults, failures, damage and other upsets. The technique that will be used to achieve the related reconfigurable control objectives is referred to as the Sequential Signal Filtering for Certainty-Equivalence Adaptive Control (SSF-CEAC). Specific Phase I tasks include: (i) Problem formulation; (i) Adaptive control design for the case of aero-only control; (ii) Adaptive control design for the case of propulsion-only control; (iii) Integrated reconfigurable aero & propulsion control design; and (iv) Performance evaluation of the IRAP system. In collaboration with Boeing Phantom Works, in Phase II we plan to pursue extensions of the proposed approach to MIMO nonlinear models, further development of control allocation strategies, pilot interface design, integrated adaptive control design for safe landing under severe failures and damage using engines only, and IRAP software toolbox development.

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.
