Abstract. The primary goal of this research is to research the stability properties of a blended-wing-body (BWB) aircraft. This section examines the assessment and selection of aircraft design parameters, planform design, reflex wing, and conducting a complete aircraft stability analysis. A BWB aircraft conceptual design has been completed, and the design. To attain static stability was examined and refined. The BWB aircraft's study was performed at three distinct values. The analytical findings were used to calculate the angle-of-attack (AOA) and hence the stall AOA. We determined the estimated initial departure angle of attack and departure region, by assessing the results of the trials and a set of stability criteria.
