The upgraded RB19 shows a modified wing tip section that has been trending in several racing teams for a while now. A crucial component of the upgrade is a metal bracket found within the boundary of the rolled mainplane. Its purpose is not only to provide a greater lateral extension for the upper flap but also reconfiguring the way the vortex formation occurs at the wing’s tip.
Due to the changes, the layout is reshaped, particularly seen in the tip section and the rear cutout post alteration. As a result, the designers have to reassess their blueprint to incorporate the necessary adjustments for drag and downforce.
In the official FIA technical submission documents, the Red Bull team acknowledged that the alterations borrow heavily from other teams’ concepts. They stated, “Taking inspiration from competitor designs, the end of the flap element has a revised curl to the endplate which offers more local load for this element for this particular upper wing design.”
Simultaneously, there’s another developing narrative involving a series of Red Bull‘s competitors. These rivals have begun studying the connection components between the wing’s upper tip section and endplate.
This new design was first recognized at the Monaco Grand Prix, showcased by Alpine and Aston Martin. Subsequently, Mercedes and Ferrari have also integrated these modifications into their own designs. Unlike Red Bull‘s update, their variant does not have the metal bracket located inside the endplate; rather, it envelops it. This design alteration affords the aerodynamicists more artistic freedom when it comes to the design of the rear cutout.
Apart from the adjustments on the rear wing, Red Bull has also made changes to the floor edge for Singapore. More camber has been applied towards the front area of the floor edge wing.
Red Bull explained these revisions by stating: “To exploit energy in the air stream, more camber has been applied to the forward part of the floor edge wing resulting in more local load from this region of the floor assembly.”
