Camber Configuration Control for Performance Optimization (C3PO)

A novel actuation concept previously used for trailing edge tab control is to be extended for use in spanwise camber control for enhanced aerodynamic performance of next generation aircraft designs. The key features of its low-power, two-position (bistable) nature and small size permit its application as secondary structure within wing assemblies, thereby allowing for flight-dependent customization of the spanwise camber to optimize vehicle aerodynamic efficiency. The proposed Phase I program will leverage previous development success of the actuation concept to scale design applications for ultimate use on transport-category aircraft, and provide risk reduction via demonstration wind tunnel tests on a scaled wing half-span model. A byproduct of the scaling law will be its incorporation within a Multidisciplinary Design Analysis and Optimization (MDAO) tool for ease of exploration of the actuation features in the context of novel vehicle configurations having flight control for performance adjustment.

Better understanding of embedded actuation for aircraft performance optimization would expand the modeling capabilities of NASA's MDAO toolset, and help provide information on anticipated technology investment benefits toward aeronautics advancement. Such actuation technology could provide the next logical step in the realization of a performance-driven control implementation for next generation aircraft concepts.

The aerospace industry can benefit from having additional design options for the incorporation of advance controls for use in optimizing the performance of their vehicles. Operators would be able to realize better fuel economy, lower emissions, and improved payload weight fraction by using embedded controls that both enhance aerodynamic efficiency while removing actuator weight from transport category configurations.

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

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.
