TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Future flight vehicles may comprise complex flight surfaces requiring coordinated in-situ sensing and actuation. Inspired by the complexity of the flight surfaces on the wings and tail of a bird, it is argued that increasing the number of interdependent flight surfaces from just a few, as is normal in an airplane, to many, as in the feathers of a bird, can significantly enlarge the flight envelope. To enable elements of an eco-inspired Dynamic Servo-Elastic (DSE) flight control system, IFOS proposes a multiple functionality-sensing element analogous to a feather, consisting of a very thin (gauge 18 or 20) tube with strain sensors and algorithms for deducing the shape of the "feather" by measuring strain at multiple points. It is envisaged that the "feather" will act as a unit of sensing and/or actuation for establishing shape, position, static and dynamic loads on flight surfaces and in critical parts. IFOS proposes to develop advanced sensing hardware and software control algorithms to demonstrate the proposed DSE flight control concept. The hardware development involves an array of optical fiber based sensorized needle tubes for attachment to key parts for dynamic flight surface measurement.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The flight surface sensing system proposed herein will extend flight research competencies at NASA by advancing innovative DSE concepts to extend the capabilities of future flight vehicles. The advanced hardware and algorithms for sensing and actuation to be developed will result in superior performance under extreme conditions from disturbances in an extended flight envelope. Importantly, these improved multi-surface DSE concepts should make all types of flight vehicles, from small single-prop airplanes to high performance, high-speed aircraft, more stable and more easily controllable, contributing still further to the safety of air flight.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Multiple commercial applications exist for the novel flight surface control system proposed here in the areas of near-space travel, air and sea defense, commercial travel and, farther afield, in motion and process control systems as used in a number of industries, including the energy sector, chemicals, manufacturing and robotics.
