Good point.
Article from Giorgio Piola and Franco Nugnes says the following:
F1 | Aston Martin: Tail wing breaks during pit stops
The aerodynamicists of the Silverstone team are particularly creative and at Zandvoort they introduced the cantilevered tail wing of the deformable structure. It is a small flap that would be useful to improve the efficiency of the new diffuser. To use this solution, the rear lift of the car was also modified, but it wasn't enough because it broke during pit stop tests. It will be necessary to intervene again on the jack, given the time and money invested in the new idea.
Aston Martin promoted the new bottom of the AMR23 and the modified diffuser, but had to give up the tail wing, the small profile that had been cantilevered from the deformable structure, under the rear LED light. The function of this micro appendage was to make the extraction of the flow from the diffuser more efficient, improving the behavior of the beam wing.
The aerodynamicists at Silverstone therefore introduced this solution in the belief that they were optimizing a package of novelties which has the ambition of gradually bringing the "verdona" back to the role of second force it had maintained in the first half of the championship.
The tail wing (literally) was broken in the pit stop tests and, therefore, temporarily abandoned, although the Aston Martin technicians had modified the rear lift: in the image by Giorgio Piola you can see the version on the right standard made of composite materials which is characterized by the vertical tongue that embraces the deformable structure, preventing the car from sliding backwards.
In the roundel on the left, on the other hand, we note the revised and corrected lifter which was designed precisely to avoid damaging the tail fin. But evidently one thing is the tyre change tests carried out indoors at the factory and another thing is when you intervene on the field in the pit lane.
The spoiler lip also broke with the revised jack, so the solution will have to be further revised, otherwise the time that would be lost at a pit stop could nullify the aerodynamic advantage of the stunt. Since Silverstone has dedicated time and money to this idea, it is likely that modifications will be sought to be able to use it without problems.
