The design for the aerodynamics of front wing based on cornering angle of a Formula-One car plays an important role on the car's performance. The cascade elements above the main front wing is enhanced with new and the deep winglets that manage the airflow for the rest of the car. The front wing cascades are attached with end plates at the extremities of the front wing to reduce turbulence. However, when the car turns, the airflow behaviour on these cascades wings changes significantly. This paper presents the aerodynamic characteristics resulting from the cornering forces subjected on Formula One styled cascade wings. The study attempts to predict the down-force and drag-force acting on the front wing under the effect of airflow change in this area. In order to investigate the airflow behaviour, computational fluid dynamics (specifically the ANSYS software) was used to simulate selected cases with specific surface definitions and boundary conditions defined in a 3D domain. It can be observed that with the increase in the car’s yaw angle during turning, the down force and the drag force decrease in an inversely proportional manner.
