Abstract: Abstract: - X-48b was taken as a reference aircraft (25% scale down version) with some modification was used as basis of our design and changes. The position of propulsion units is a major design change in our aircraft and is submerged inside the structure. Winglets are curved unlike a straight vertical component. The concept of split rudder is implemented for directional control along with alternate variation in the RPM of the motors. The dimensions are mostly based on 25% scale down X48-B with minor variations. The location of propulsion units is decided on the basis of requirement. A mission profile is designed to facilitate the selection of propulsion units. Coefficient of lift for cruise flight is calculated and the corresponding CD is obtained from the graphs of reference aircraft. Further , the drag at cruise is calculated which is nothing but the thrust required . Electric ducted fans(EDFs) with appropriate specification are selected based on the mission profile. The concept of Elevons is implemented for rolling and pitching moment. For designing the control surfaces , general guidelines are referred. Expanded Polystyrene (EPS ) is used as the fabrication material along with plywood , balsa wood and carbon fiber rod for the structural integrity.14.8 volt lithium polymer power pack is used for power supply. Servo actuators are used for control surface movements. After completing the fabrication, the aircraft was taken to flying field and the system functioning was checked thoroughly. The test flight was carried out successfully and a general behavior of the aircraft during the flight was observed. A 3D model was created in XFLR5 and was analyzed under flight conditions. The graphs obtained were found to have similar pattern as that of the reference aircraft, which validates the analysis.
Keywords: Winglets, propulsion, mission profile.
