4.0 rồi nói chuyện bằng khoa học đi anh ơitôi khẳng định cái spoiler kia là có tác dụng giảm cản gió luôn đấy, không phải là đánh đổi cản gió để lấy downforce đâu... anh không biết thì cũng không nên ý kiến nhiều cho nó lộ ra...
để tăng downforce người ta dùng wing, spoiler là để giảm drag... anh có biết wing với spoiler khác nhau như thế nào không? hay anh nghĩ hai thứ đó là một như rất nhiều người thiếu hiểu biết khác?

tóm tắt cho anh nào ko đọc được
The numerical analyze of high-speed passenger car with first rear spoiler design (case #2, which was a wing style spoiler) has showed that the aerodynamic drag is reduced from 0.232 to 0.192, which is 17% drag reduction, and it also increases negative lift by reducing the lift coefficient from -0.222 to -0.239, which is 7% lift reduction. By comparing Figure 5.8 and Figure 5.9 it has been found that; the recirculation zone above the rear window was almost gone by using wing style spoiler (first spoiler). The air sloped gently above the rear window, which helps keeping the rear window cleaner. Numerical analysis has showed us that the second spoiler design (case #1, which was mounted to the edge of rear-end of the vehicle without leaving any gap between spoiler surface and vehicle surface) provided more negative lift force than the first spoiler shape did but provided less drag reduction. It provided 6% drag reduction (dropped the drag coefficient from 0.232 to 0.217) but the negative lift force has been increased by 17% (dropped the lift coefficient from -0.222 to -0.268).
case 1 là spoiler : giảm 6% drag, tăng 17% downforce
case 2 là wing : giảm 17% drag, tăng 7% downforce
=> giảm drag thì lắp wing, tăng downforce thì lắp spoiler
