Aerodynamic Devices -2
As we looked into rear wing in the previous blog. Now we are going to look into some minor aerodynamic devices which are going to aid the main aerodynamic device or major aerodynamic work independently to help produce effective downforce. Slots , cutouts and end plates of rear wing Source : motorsport.com As there is a low pressure zone under the aerofoil , the air from above tends to move down the aerofoil to form vortices, which is a turbid flow and slows down the air flow , that means high drag. To over come this a end plate is kept at both the corners of aerofoil which prevent the movement of air sideways . But It also tends to form another type of vortices known as Wing tip vortices , which occurs at the tip of aerofoil that is at the top of end plate. To overcome this again , slots are placed in the end plate. So some energy rich air pass through this slot that create a high pressure area outside the wing. Then the cutout plays a huge role in creating counter vortices
