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

(Motorsport-Total.com) – The current 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 reveals that in the Liberty Media period, Formula 1 isn’t 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 take a look at the rear


The 1978 Brabham fan automotive that drove Niki Lauda to victory in Sweden is a tremendous automotive due to its uniqueness and can without end be a speaking level.

Second, it confirmed that lawmakers’ wrestle to search out guidelines that all the time contribute to the larger image is unlikely to finish. Let’s check out the fan automotive and the issues Formula 1 is making an attempt to resolve.

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

In basic, the present guidelines will apply till 2025, however there are plans to see one thing fully totally different till 2026. As for working by way of 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 automotive to know what the final factor is. We’ve checked out fan machines, all types of wise issues. The 2026 automotive will likely be standard, as a result of that is what we wish. But the efficiency will in all probability be higher than the 22 automotive.”

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

Lotus 78 vs 79 Comparison

Comparison between Lotus 78 and 79 scaling

When you consider land influence machines, you’ll be able to’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 vital to do not forget that the 1979 automotive owes a lot of its success to its predecessor, as the group needed to overcome some challenges to get energy from venturi tunnels and use skirts.

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

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

Brabham BT46B

The Brabham BT46B was used for only one race scaling

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

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

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

The racing board finally noticed match to ban skirts and introduce a minimal journey peak for security causes, whereas groups continued to push for larger 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 thinking about 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 attributable to the car in entrance and on the automobiles behind it.

The sport’s final main try to alter this case was in 2009, when the complexity of the automobiles was drastically decreased 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 because of 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 end result was a agency however broad sufficient imaginative and prescient that groups rapidly tried to beat, and because of this, these efforts failed because of technical and political will.

In 2014, because of the introduction of turbo-hybrid drives, the aerodynamics of the automotive 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 alteration, the governing physique needed to make one other course correction, utilizing a few of the classes discovered in the research for the 2021/22 mission to scale 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 decreased.

The rear wing slats, which groups had used for greater than a decade to change 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 group was tasked with redesigning the automotive platform, and the guidelines have been additionally written from the floor up.

This is meant to eradicate a few of the inefficiencies attributable to 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 steadiness of energy between the groups.

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

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