Abstract

In this research, CANARD and its vertical and longitudinal positions effects on PRESSURE DISTRIBUTION and AERODYNAMIC COEFFICIENTS of a maneuverable aircraft wing model have been investigated numerically applying the fluent software. The investigations have been performed at the Reynolds number of 5×105 and different angles of attack, using unstructured grid and the Reynolds stress modeling. The applied wing and CANARD are delta shape and the supposed CANARD longitudinal positions are front, middle and rear, and its vertical positions are up, middle and low, respect to the main DELTA WING. For the case of no CANARD configuration model, the obtained results show that until angle of attack of 25 degrees, there is a very good agreement between the experimental data and the numerical results. Adding the CANARD causes the vortex on the wing upper surface become stronger and bigger. Also, for all longitudinal and vertical positions of the CANARD, the CANARD’s wake passes over the main wing surface. When the CANARD is at forward-up position respect to the main wing, the highest amount of lift force achieves. Furthermore, the least amount of drag force relates to the case which the CANARD is closer to the main wing and along with its axis. However, maximum amount of aerodynamic performance achieves when CANARD is at down-forward position respect to the main DELTA WING.
