Aerodynamic analysis of Saab 340B aircraft with data fusion implementation

This paper conducts an aerodynamic analysis of the Saab 340B passenger aircraft, employing AVL and as numerical methods and DATCOM as a collection of engineering methods and empirical data that provide a set of aerodynamic coefficients for assessment. The investigation is focused on examining the longitudinal aerodynamic behavior of aircraft, specifically considering the impacts of flaps and elevators at varying angles of attack. The outcomes from the clean configuration are compared with the results obtained from computational fluid dynamics studies found in existing literature. While the results may not precisely match, they capture the general trends in the behavior of the aircraft. This aligns with the expected outcomes from preliminary methods like AVL and DATCOM. Data fusion techniques are strategically employed to integrate insights from these diverse sources, enhancing the overall accuracy and reliability of the aerodynamic assessment. The research aims to provide a comprehensive understanding of the clean configuration's aerodynamic performance, contributing significantly to the advancement of aviation technology.
