| Abstract | This research uses Neural Networks to determine two dimensional airfoil geometry using Bezier-PARSEC parameterization. Earlier, Ant Colony Optimization (ACO) techniques have been used to solve combinatorial optimization problems like TSP. This work extends ACO method from TSP problem to design parameters for estimating unknown Bezier-PARSEC parameters that define upper and lower curves of the airfoil. The efficiency and the performance of ACO technique was compared to that of GA. The work established that ACO exhibited improved performance than the GA in terms of optimization time and level of precision achieved. In the next phase, Neural Network is implemented using Cp as input in terms of Cl, Cd and Cm for learning and targeting the corresponding Bezier-PARSEC parameters. Neural Networks including Feed-forward back propagation, Generalized Regression and Radial Basis were implemented and were compared to evaluate their performance. Similar to earlier work with GA and Neural Nets, this work also established Feed-forward back propagation Neural Network as a preferred method for determining the design of airfoil since the technique presented better approximation results than other neural nets. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
