How Mercedes ’Miami F1 updates brought a false dawn

But as the weekend wore on, Mercedes he could not regain that form and again found himself in battle at the head of the midfielder, not s Ferrari and Red Bull.

What Mercedes needs to figure out now is whether it flattered him Friday or was worse for the rest of the weekend.

One of the factors that hit Mercedes on Friday seems to have been that its struggles with tire warming were masked by track temperature and a lack of tires on the new surface. This contributed to the team being able to find a sweet spot while running on Friday, something they failed to achieve on Saturday as the grip increased and the track developed.

Although Mercedes made some changes to the settings between Friday and Saturday, in an attempt to pull off more performance, the shape of the rollercoaster at least confirmed to the team that the problems with its W13 are not entirely aerodynamic in nature.

In fact, the harmful effects caused by porpoises are just one of the pieces of the puzzle that the German carmaker needs to solve in order to get the best out of the W13.

Mercedes has unveiled a handful of new components for the Miami GP to try to improve performance and meet the demands of the new track. While struggling to solve the car’s problems, the team’s design ingenuity certainly doesn’t seem to be suppressed – as its new front fender design is by far the most unique interpretation of the new regulations we’ve seen so far.

So far, most teams have followed the line in terms of front wing element design and end plate joint, and each of the designs is similar to those introduced by FOM before the start of the season.

Regulations in this region of the car have been deliberately formulated to work in conjunction with 18-inch wheels, lower-profile tires, wheel covers and less complex brake channel designs, to reduce the amount of flushing that was possible under the previous ordinance.

However, Mercedes ’approach represents a somewhat paradigm shift, as the resulting changes are likely to be responsible for a significant shift in local airflow behavior, which in turn will affect the track created by the front tire.

To facilitate this, the flap design on the outer end of the wing has been completely redesigned, resulting in an overturned front edge of the main plane and a significantly shortened tendon length.

It also allowed the three folds to then be positioned further forward on the end plate when viewed from the side, requiring them to move forward quite aggressively.

This also results in a narrow radius at the joint between the flaps and the unwinding end plate. Instead, it has been replaced by angular surfaces.

All of these changes lead to the detection of an edge on the end plate that would otherwise be connected to the dampers, not only creating a path for airflow to exit before but also at a higher point.

Interestingly, on both of the uppermost flaps there are also parts that have slots like feathers (red arrow) that are likely to produce a set of smaller vortices that will help manage the vortex of the core created at the intersection of the flap and end plate.

You will notice that a metal construction is used to reinforce the curved outer part of the upper two flaps to make it easier to manage the associated loads.

The changes found on the front of the car aren’t the only ones the Miami team has made, as it has also overhauled its rear wing.

The design, however, was not specific to the circuit, as it was already looking for ways to change the thrust level during the last few races, adding and removing Gurney’s trailing edge and trimming the top flap to change the load created and with it and pull (previous specification insert). , below, with a dashed line showing how much of the upper flap has been cut off).

The wing redesign not only featured a revised top flap, as the turned front edge of the main plane was also discarded, while the design took up less space within the allowable box section, which can also be seen with a more open corner radius where it joins the end plate (blue arrows).

Changes have also been made to help reduce the beam wing strength, as the trailing edge of the upper element has been cut to reduce the length of the tendon of that element (red arrow).
