Abstract: This project presents design process for a medium range unmanned aircraft. The objective is to design an aircraft which carries high payload with restricted wing span. The project deals with study of various innovative techniques to improve the aerodynamic performance of the aircraft. It emphasizes on usage of box wing technology after considering various aspect of design and fabrication. The design process involved is a conventional design cycle with initial sizing and trade studies followed by analysis for the validation of the design. The study of the downwash and effect of the stagger angle due to two wings on their aerodynamic performance was also carried out. Flow analysis for the required conditions of cruise is performed and had shown that the lift is sufficient and drag is slightly high. For the applied loads the structure designed has stresses within the limits of the structural integrity. The propulsive force required was comparatively high when compared to single wing of same area.
