Aircraft configuration design involves multiple disciplines such as aerodynamics, structures, propulsion, control, and avionics systems. While there is plenty of information available in literature regarding the design procedure of aircraft for the above-mentioned disciplines, there is no method available to objectively evaluate various configurations in conceptual stage towards selecting best configuration. As a result, even today the final aircraft configuration is finalized by experienced designers based on their heuristic knowledge acquired from their experience. A new approach to objectively select the best configuration is proposed using Discrete Multi Criteria Decision Making method (D-MCDM). As a case study, five configurations are designed for a High Altitude Pseudo-Satellite (HAPS) using standard aircraft design procedure. Their aerodynamic performance parameters are estimated using Flight Stream software, a surface vorticity based medium fidelity software. Subsequently all the configurations are evaluated using D-MCDM methods, such as Weighted sum method (WSM) and Weighted product method (WPM). Then, based on the aerodynamic index obtained from the D-MCDM study, considering various performance parameters, the optimal configuration for HAPS is determined.
