Mercedes F-Schacht: Lotus officially protests

Mercedes F-shaft
Subscriptions & booklets

V last week the technical directors of the teams met with the FIA ​​race director Met Charlie Whiting. It was one of their regular meetings. As expected, one item on the agenda was the tiresome subject of the F-shaft. The opponents tried to convince the rulers that the controlled stall on the front wing via a channel system, which is stored with air via two holes in the rear wing end plates when the DRS button is pressed, was illegal.

It came new and old arguments on the table. Lotus insists on the old one. The fifth place in the World Championship sees the driver's unauthorized interference with the aerodynamics when the F-slot is actuated with the DRS button. Technology director James Allison warned that the legalization would leave completely different options open as to how the DRS button could be assigned secondary functions.

As announced exclusively by auto motor und sport on Wednesday, Lotus in Shanghai will have it on Thursday (April 12th) officially protested against the Mercedes technology coup. After all, the opponents of the DRS system were fair enough to submit their objection to the FIA ​​in good time before the race weekend. If the stewards agree that Lotus is right, Mercedes could convert to a conventional rear wing and thus paralyze the F-slot in the front wing.

Since the accusation does not contain any really new findings, the FIA ​​cannot be assumed to have its own Will change opinion on the legality of the DRS-activated F-slot. The stewards will of course not only get the opinion of Lotus before their decision, but also that of FIA race director Charlie Whiting and the technical experts in the ranks of the association such as the technical delegate Jo Bauer.

Come the case before the FIA ​​Court of Appeal?

Since the wing has already been classified as legal twice during the technical inspection at the racetrack, it is not to be expected that the commissioners will suddenly give their opinion in Shanghai to change. If Lotus is really convinced of its arguments, the chances are high that the racing team will then turn on the FIA ​​appeals court to review the decision of the experts at the track.

McLaren will in no way go against his Motor supplier Mercedes take action and stay out of the matter. But from the ranks of the F-slot inventor came a thought that had a little more substance than the criticism ofLotus.

Since air is directed through two holes in the rear wing end plates into a duct system that blows this air back out into the open through four slots on the front wing, if the wording is interpreted exactly, one could say that the internal flow is due to The two open ends also have an effect on the air flow on the outside.

As a result, according to the regulations, the openings at the back and front must comply with the 100 millimeter radius, which is of course not possible due to the angular contours. But even this hair-splitting process is not given great opportunities. Anyone who brings this thought to the end would also have to forbid cooling ducts and airboxes.

Sauber is already working on the F-duct copy

It has been surprisingly quiet over the past few days around Red Bull. The defending champions apparently left the saber rattling to Lotus. Probably because you've been working on your own system for a long time. Not only the top teams have already started the development machinery in this direction. At Sauber, too, the engineers are already thinking about how a duct system could be integrated into the car at a later date.
