What thoughts about the “fan machine” say about the future

(Motorsport-Total.com) – The latest revelation that these in command of Formula 1 briefly toyed with the concept of ​​including so-called fan automobiles to the new guidelines from 2026 is fascinating in two methods. First, it exhibits that in the Liberty Media period, Formula 1 is not any slouch and holds nothing again in relation to making the Grand Prix automobiles as race-ready as attainable.

The Brabham BT46B was spectacular with its vented have a look at the rear


The 1978 Brabham fan automobile that drove Niki Lauda to victory in Sweden is an incredible automobile due to its uniqueness and can perpetually be a speaking level.

Second, it confirmed that lawmakers’ battle to search out guidelines that all the time contribute to the greater image is unlikely to finish. Let’s check out the fan automobile and the issues Formula 1 is making an attempt to unravel.

The concept for a fan-powered automobile appeared eventually month’s worldwide Autosport present. Chief Technology Officer Pat Symonds spoke there about how open the sport is by way of the future route of the automobiles.

In normal, the present guidelines will apply till 2025, however there are plans to see one thing fully completely different till 2026. As for working by potential adjustments, Symonds mentioned, “When we have been researching Project 2026, we had a clean slate and we have been exploring various things.”

“We’ve even gone again to the ground-effect automobile to know what the final factor is. We’ve checked out fan machines, all kinds of smart issues. The 2026 automobile will probably be typical, as a result of that is what we wish. But the efficiency will in all probability be higher than the 22 automobile.”

Formula 1 designers like to attract inspiration from the previous, so it is no shock that Symonds and the technical crew checked out how skirts and followers may very well be utilized in the present Ground-Effect period with trendy growth instruments. can be utilized.

Lotus 78 vs 79 Comparison

Comparison between Lotus 78 and 79 scaling

When you consider land affect machines, you may’t assist however consider the Lotus 79 or ‘The Black Beauty’ because it was identified at the time for its beautiful black and gold paint job.

However, it is necessary to keep in mind that the 1979 automobile owes a lot of its success to its predecessor, as the crew needed to overcome some challenges to get energy from venturi tunnels and use skirts.

The trials and tribulations of the ’78 automobile have been really good for Lotus, as the competitors did not imagine in the degree of efficiency achieved in 1979. As a outcome, everybody else was left behind and needed to catch up.

At the 1978 Swedish Grand Prix, when Brabham unveiled its B-Spec BT46, also called the “Fan Car”, one other idea explored by FOM appeared and instantly outshone the competitors. The fan pumped the automobile to the floor and the quicker it went, the extra downforce there was.

Brabham BT46B

The Brabham BT46B was used for only one race scaling

As effectively as being quick, the BT46B was an ingenious answer to the drawback Brabham could not reply to shortly in the type of venturi tunnels.

The drawback was that the automobile was powered by a flat 12-cylinder Alfa Romeo engine, which restricted the area wanted for tunnel building.

The efficiency was so sturdy that the competing groups have been upset. Pressure mounted on Bernie Ecclestone, who at the time was not solely Brabham’s proprietor but in addition head of FOCA (Formula 1 Constructors’ Association), so the automobile was withdrawn after one race and one win.

The racing board finally noticed match to ban skirts and introduce a minimal experience peak for security causes, whereas groups continued to push for increased efficiency.

Formula 1 expertise and security have improved considerably in the practically 40 years since these ideas have been final utilized in the sport, so there could also be causes for a return.

But in the end, FOM is just considering delivering automobiles that may compete with one another – there are higher options for that.

Formula 1 historic drawback

The driving drive is the impact of the turbulence brought on by the car in entrance and on the autos behind it.

The sport’s final main try to alter this example was in 2009, when the complexity of the automobiles was drastically diminished in comparison with their predecessors. While the intentions have been good, they weren’t as complete as the 2021 plan, which needed to be pushed again to 2022 attributable to the pandemic.

Ferrari comparison between 2008 and 2009

Between 2008 and 2009, automobiles have been considerably simplified scaling

In 2009, an Overtaking Working Group (OWG) was tasked with discovering methods to mitigate the drawback, however they didn’t have the time or sources of the FOM at the time.

The outcome was a agency however broad sufficient imaginative and prescient that groups shortly tried to beat, and because of this, these efforts failed attributable to technical and political will.

In 2014, attributable to the introduction of turbo-hybrid drives, the aerodynamics of the automobile was revised.

However, when confronted with a drop in efficiency in comparison with the earlier period of automobiles, there was a knee-jerk response, which led to the growth of a extra aerodynamically environment friendly setup for 2017, the place considerably bigger bargeboards have been once more a key ingredient in the recipe.

As a results of this modification, the governing physique needed to make one other course correction, utilizing a few of the classes realized in the examine for the 2021/22 venture to cut back the drive of the entrance and rear wings.

Thus, the cascades on the entrance wing have been eliminated, the struts on the underside of the wing have been restricted, and the variety of components was diminished.

The rear wing slats, which groups had used for greater than a decade to switch the vorticity at the tip, have been additionally banned, and the wing dimensions modified considerably.

Front wing 2018 and 2019

Private areas have been additionally redesigned between 2018 and 2019 scaling

However, the plan for 2022 was rather more complete: a big crew was tasked with redesigning the automobile platform, and the guidelines have been additionally written from the floor up.

This is meant to get rid of a few of the inefficiencies brought on by repeated adjustments to the guidelines over the years, which frequently depart loopholes.

To bolster this effort, adjustments have been additionally made to the Sporting Regulations to change the stability of energy between the groups.

Although present guidelines are designed to include issues, groups all the time discover a option to cease these efforts, requiring a recent begin.

That’s why 2026 has been set as the date, which is important because it brings down the curtain on the present technology of turbo-hybrid powertrains which have outlined the sport since 2014.
