Abstract: Tandem wing configuration is similar to a biplane, however in these aircrafts the wings are offset horizontally far enough that the centre of gravity falls between the two lifting surfaces. Because the wings are further apart than with the biplane, it minimizes the downwash effect on the second wing. This design provides with a higher lifting capacity than with a single wing, while not increasing the overall dimensions of the aircraft. The lift generated by the wings of these aircrafts depends greatly on the angle of attack at which the airfoils are attached to the fuselage. Through this project we are carrying out Computational Fluid Dynamics analysis of the flow over a tandem winged aircraft, in order to determine the angle of attack at which maximum lift is obtained. The two-dimensional analysis, using CFD, of tandem or staggered arranged airfoils of the canard and wing of an Eagle 150 aircraft is carried out in this study. The tests is carried out with tandem and staggered placement of the airfoils in order to determine the optimum position of the wing with respect to the canard and also to determine the lift coefficient at various angles of attack. ANSYS software was used to study the aerodynamic performance of a two-dimensional model the airfoils which was created using PROFILI software.
