The improve on the RB19 incorporates the semi-detached wing tip part that has been pursued by the opposite groups for a number of races now.
The brand new association has a steel bracket that sits contained in the rolled mainplane boundary upon which the higher tip part resides.
This not solely leads to the higher flap being prolonged laterally but in addition alters the way in which the vortex will type on the tip.
This clearly has an impression on the form of not solely the tip part but in addition the rear cutout thereafter, with the designers having to rebalance their design to consider downforce and drag necessities.
Explaining the change within the official FIA technical submission paperwork, Purple Bull was open that it had copied the concept from others.
“Taking inspiration from competitor designs, the top of the flap aspect has a revised curl to the endplate which affords extra native load for this aspect for this explicit higher wing design,” it stated.
In the meantime, there’s a parallel growth program underway from a variety of Purple Bull’s rivals, who’ve additionally seemed on the approach the higher tip part of the wing and endplate are related.

Apparently, this was launched concurrently by Alpine and Aston Martin on the Monaco Grand Prix, and has since been embraced by Mercedes and Ferrari.
Comparatively, their variant doesn’t have the steel bracket sit inboard of the endplate, somewhat it frames it. This in-turn permits the aerodynamicists to take a extra liberal strategy with the design of the rear cutout.
The rear wing isn’t the one change that Purple Bull has delivered to Singapore, with the group additionally making revisions to the ground edge. The group has utilized extra camber to the ahead portion of the ground edge wing.
Explaining the reasoning behind making this improve, Purple Bull stated: “To use power within the air stream, extra camber has been utilized to the ahead a part of the ground edge wing leading to extra native load from this area of the ground meeting.”
