FORCE INDIA’S NEW REAR WING ENDPLATES
Force India has made a couple of tweaks to the VJM09’s rear wing endplates. First, the team’s aerodynamicists have extended the strakes that guide the airflow upwards – otherwise the air naturally tends to dip (compare the yellow arrows). Overall, these aero elements contribute to the phenomenon of airflow deflection that happens at the rear of any F1 car.
The lower endplates are also more serrated with four dents instead of three. These create a series of curved vanes that push the air to the outside and thus participate in the expansion of the airflow coming from the diffuser. The vanes also sport a different outline, which is more vertical and less curved.
