TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
This proposal is in response to NASA SBIR Topic A2.08 in the area of "Variable Fidelity, Physics-Based Design/Analysis Tools". The development of a coupled viscous/inviscid analysis tool for powered-lift airfoils and wings is presented. In this context, powered-lift airfoils are taken to be airfoils under the influence of a high-energy jet, and include jet-flaps, augmenter-flaps, upper surface blowing, and circulation control airfoils. This methodology consists of coupling a viscous jet analysis, using a finite-difference approach, with a potential flow panel calculation. The method uses an iterative procedure to capture the effects of viscous mixing and determine the correct jet shape. The goal in developing 2-D powered-lift predictions is to couple this analysis with a pre-existing modified Weissinger method to accurately predict 3-D wing performance based on sectional data. In this manner, high-lift wing characteristics can be determined at a fraction of the computational cost of CFD. An MDAO framework for aircraft-level optimization will be developed with the goal of integrating the powered-lift analysis such that ESTOL concepts and technologies can be incorporated at the conceptual and preliminary design stages.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
This tool would have immediate application in NASA MDO toolkits. It would also serve as a useful resource in analysis of unconventional systems and allow for parametric design studies of powered-lift systems. AVID's experience in software development with easy-to-use, intuitive graphical interfaces would also make this product a viable commercial quantity. Potential customers include small-business UAV companies, engineering analysis and design groups, and universities.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Non-NASA Commercial Applications would be similar in nature to the NASA Commercial Applications addressed above.
