TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Research is proposed for the development and implementation of state of the art, reduced order models for problems in
nonlinear aeroelasticity. Highly efficient and accurate aeroelastic simulation tools will be constructed based upon the
mathematical formalism of optimal prediction theory and a novel implementation of a filtered harmonic balance solution
methodology. The implications of the proposed work include orders of magnitude reduction in computational time, with minimal
loss of accuracy, for time periodic problems in nonlinear aeroelasticity. The application of the proposed innovations spans the
range of flight, from high-speed transport vehicles, to small-scale, flapping Micro-Air vehicles. Anticipated results include 1) the
implementation of the proposed reduced order methodology into both a standard grid-based aeroelastic tool and a material
point method monolithic aeroelastic solver for the production of technology ready, multi-flow regime aeroelastic simulation
tools 2) application of the proposed work to large-scale simulation and comparison with experiment and "full-order" aeroelastic
simulations and 3) advancement of the state of knowledge for nonlinear problems in aeroelasticity in both the subsonic, low
Reynolds number regime and transonic high Reynolds number regime.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
A broad range of NASA applications exists for the software infrastructure that is expected to result from this SBIR effort, and
NASA centers will be the initial target. The direct application to the NASA represents a prime opportunity for further product
development and enhancement, as well as a potential revenue stream from engineering support and technology acquisition.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Various DoD components likely to have interests in this technology are the US Air Force, Army and Navy. Particularly, Air
Force has a lot of research going on in aeroelasticity. Non-military applications represent another potential market sector.
Improvements in the computational accuracy and efficiency for aeroelastic modeling are needed for a wide range of
aerospace, ocean, and general engineering applications. The accurate assessment of aero-structural properties of aircrafts
has been known to be very important in designing safe aircraft. Companies such as Boeing, Bell, Sikorsky, and AeroVironment
are our industrial partners, and during our briefing for the technology to be developed in this SBIR, they indicated their strong
interest. They will be actively involved in this project and they are expected to be immediate users of the end product. In
addition, Pratt & Whitney, General Electric, General Dynamics, and Lockheed Martin represent other potential customers that
we intend to aggressively pursue. And finally, corresponding companies in Europe and Asia represent an opportunity for
exporting the resulting methods and technologies, provided that the NASA permits us to do this.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
