How F1’s new cars have given teams a huge design challenge

F1's new technical rules for 2022 have been broadly anticipated to supply a set of vehicles that regarded almost equivalent, but there was appreciable range in design up and down the pit lane as groups attempt to discover methods to outsmart one another. sat down with AlphaTauri Technical Director Jody Egginton to seek out out extra in regards to the challenges that groups have confronted.

After a pandemic-induced delay of 12 months, 2022 noticed the long-awaited arrival of a model new set of F1 technical rules aimed toward making the racing extra thrilling.

The brand new guidelines embrace tighter limits on bodywork, a transfer from 13-inch to 18-inch tyres, and the reintroduction of floor impact as a way of producing downforce.

This ensured that groups have had little to no carryover from their 2021 vehicles, forcing designers to start out with a clean sheet of paper in penning their 2022 mounts.

So what have been the largest challenges in designing a automotive to evolve to the brand new rules?

“The very primary and apparent reply is the aerodynamics – it was a very new idea,” AlphaTauri Technical Director Jody Egginton advised in an unique interview.

“We’re ranging from scratch, so there was a variety of new applied sciences that we weren’t conversant in, like the ground and the Venturi [tunnels underneath the car].

“[Another] huge dialogue level was ensuring we may get the automotive underneath the load restrict, which has been fantastically difficult for all groups, I am positive.

“The protection and crash checks are tougher as nicely now, and it’s a must to go the take a look at to be able to homologate the automotive to check and race, however equally, together with desirous to package deal the automotive as tightly as potential and preserve the factor on the minimal weight restrict, it is a huge problem.

“However the aero idea was the primary [time we thought] we have actually received to take a look at this, and also you’re on such a steep studying curve even now, at first of the event cycle, so I might say automotive packaging and the aerodynamic idea was the massive space of studying.”

Getting a deal with on porpoising

With the 2022 vehicles wanting very completely different from their predecessors, it’s maybe unsurprising that they need to additionally deal with and behave in vastly alternative ways.

Some of the noticeable options of the brand new vehicles is the way in which they have a tendency to porpoise up and down at excessive pace.

Some groups seem to undergo with this greater than others, although Egginton mentioned AlphaTauri are managing to comprise the difficulty, including that it might be prevalent at some circuits greater than others.

“We have skilled it on and off,” mentioned Egginton.

“It is laborious to say precisely the place the [other] groups are, however we will make our automotive do it, after which each time we do this, we get a greater understanding of it.

“We’re managing to work round it now and may management it, however there’ll seemingly be circuit-specific facets of it – simply since you’ve received it totally underneath management at [one] circuit, it does not imply it will not are available at [another].”

Whereas there are numerous variables that affect the severity of the porpoising, Egginton famous two explicit areas which have a very huge half to play.

“In very normal phrases, there’s experience peak sensitivity and stiffness sensitivity, so the mixture of these two offers you instruments to form of handle it,” mentioned Egginton.

“However on the similar time, there’s an attractiveness to get the ground into the experience peak zone the place there’s probably the most efficiency, so you do not wish to be too compromised. You wish to be on the sting of it, however you do not wish to overstep the mark.

“Then you have to think about that throughout low gasoline, excessive gasoline, DRS on, DRS off. There’s a variety of issues to think about.

“However the thought is to maximise the aero package deal as a lot as you may round what you’ve got received, and on the similar time, attempt to develop in a path that minimises the possibility of getting [porpoising].”

Porpoising "a problem to simulate"

Egginton additionally defined why porpoising is troublesome for groups to precisely simulate in a wind tunnel.

“It is difficult to simulate it totally [in a wind tunnel], as a result of it occurs at very low experience heights,” mentioned Egginton.

“In the event you’re not diligent within the wind tunnel, you might have your flooring crash into the wind tunnel belt, so it is troublesome to simulate.

“You’ll be able to simulate it in [computational fluid dynamics] to some extent, however there’s a lot of variables, and the CFD instances can be fairly advanced, together with the affect of highway or circuit roughness, after which it’s a must to correlate it.

“We had a view that there was a danger that at sure experience heights it will grow to be an issue. When it occurred, we weren’t completely shocked.

“You are constructing your database of understanding what’s influencing it, how the geometry modifications in your flooring have an effect on your aero efficiency, how the stiffness of your flooring reacts, and then you definitely get to the tip and also you construct up a variety of information. However I do not suppose you get all of that simply from a simulation.”

Minding the cap

One other hurdle to beat this yr is the transfer to a finances cap of $140 million per yr (down from $145 million), that means groups must be particularly vigilant about how and the place they spend their cash.

“Clearly, you wish to spend the cash correctly when there is a new set of rules; there’s extra unknowns, so you have to be centered on that,” mentioned Egginton.

“We additionally needed to plan very early on what our seemingly improve technique can be, so you have to plan ahead, you have to get the cash to go so far as it must go.

“For us as a staff, the finances cap figures should not so completely different to what we have been working at, however every thing’s new this yr.

“We’re actually centered on ensuring the cash is spent on the bits of the automotive which can be efficiency differentiators, and we’re not throwing cash at widgets.

“We all the time saved a watch on it, as a result of we have been by no means in a state of affairs the place the finances was with out finish, however we’re actually centered on it now.

“The principle coverage is to maintain cash accessible for updates. With the brand new automotive design, when you discover one thing actually performant, you need it on the automotive, and also you want the money to do it.

“So [you need to] preserve the cash accessible for so long as potential, and just remember to do not waste it [or] have any left on the finish.”

An important range of automotive designs

Many inside F1 thought that the restrictive nature of the 2022 rules would lead to a subject of nearly identical-looking vehicles.

In actuality, nevertheless, there was a substantial range of design all through the pit lane, with Mercedes’ uniquely-tapered sidepods setting tongues wagging after they broke cowl throughout pre-season testing.

“I am fairly positive that the majority groups may have tried issues just like what they’re seeing on different groups,” mentioned Egginton.

“Most likely not as excessive as [Mercedes’ sidepods], however I feel there’s facets of what they’ve completed there which individuals would seemingly have checked out.

“But when anybody else had put the equivalent idea in, then I might have been questioning whether or not there was one thing occurring!

“I can see frequent strands in a variety of what folks have completed, however everybody’s clearly put collectively what they consider is the quickest automotive, and [the designs] are fairly numerous.

“There are some constraints on what you are able to do [with] the chassis, however past that, there’s loads of freedom, and persons are nonetheless investing an enormous period of time in packaging and cooling programs.”

No good answer on the F1 grid but

F1 historical past is suffering from examples of technical improvements which have swiftly been imitated by different groups, and Egginton feels this development will proceed into 2022 as groups grow to be extra accustomed to the brand new rules.

“There will be convergence, there all the time is,” mentioned Egginton.

“The query is what mixture of strategy is the optimum answer. Is it any singular staff [that has the best solution], or is it a mixture [of teams]? Groups may have different options within the background, however possibly they don’t seem to be mature sufficient but.

“I do not suppose any single staff’s answer is the last word answer, however it’s early days.”
