As Formula 1 introduced a raft of changes ahead of the new season, 2017 was always likely to produce some new features on the aerodynamic front. Here are some of the key highlights from this year.
The appearance of T-wings on this year’s cars is a consequence of the changing of the rear wing dimensions for 2017. During the rewriting of the rules a small region that was previously occupied by the outgoing higher rear wings was accidently left unattended. The extruded 50 x 750 mm area was instantly taken advantage of by the teams, with the majority of them converging on some form of twin element design by mid-season.
Mercedes were one of the first teams to debut a T-wing in 2017
Procrastinating a little bit from revision by sharing some of the illustrations that I’ve done over the season so far. You can find the associated articles on Motorsport Week that explain the effects of these developments in detail.
The teams had barely hit the track when Renault were called out over their rear wing support design (inset). The design was edited in a cheekily manner, dodging the regulations that stipulate that the DRS actuator must be isolated by slimming the support.
McLaren’s pace in the final sector in Barcelona shows that their chassis is reasonable, certainly above the other midfield runners but not quite there with the top dogs. The team’s aero department are constantly churning out alterations to the car – the front wing is tweaked almost every race weekend.
The FW40 isn’t a striking car in design terms but the chassis clearly works cohesively on both aerodynamic and mechanical fronts. The above front wing was altered twice within the same amount of weeks between Australia and China.
Ferrari’s development rate has been refreshing in 2017. In Bahrain the Scuderia introduced their front wing proper for the season (left), featuring six elements cutting the entire span and a more pronounced vortex tunnel.
Pretty in pink: It doesn’t matter what colour the Force India is in, the team continue to punch well above their weight despite the regulation changes. The design office is creative and not afraid to produce complex geometries such as their bargeboards and splitter above.
Mercedes unleashed an extensive aerodynamic overhaul to the W08 in Barcelona. The nose, bargeboards and engine cover were heavily revised while the spoon-shaped rear wing was ousted for a conventional design. A monkey seat winglet straddles the rear crash structure to draw the exhaust plume upwards.
Red Bull’s ‘struggles’ has pushed Adrian Newey back into action, although it would be unfair to say that they got the car wrong. The RB13’s clean design leans more towards drag reduction than outright downforce and the car is often up top of the speed trap charts. More complex bargeboards arrived in Spain – is this the start of their come back?
If you haven’t already caught some of my tech analysis in the past couple of Motorsport Monday magazines then here’s your first glimpse of some: I dissect McLaren’s new front wing (only on Alonso’s car) and also explain what is going wrong (again) with the MCL32 powertrain – it’s not all Honda’s fault! You can also find some mini-articles on developments from Australia on the Motorsport Week website.
Also, a quick question I would really appreciate some responses to: Would anyone be interested in buying a print of one of my many illustrations? Obviously we don’t all want a framed McLaren front wing but something more like the Mercedes W05 below might take your fancy.
If you haven’t heard already, F1 is set to ban the hydraulic heave springs that many teams (notably Mercedes) have been playing with over the past 12-15 months. Although it is not an official ban as yet, a technical directive has been issued to the teams addressing the claims that Ferrari raised in a recent letter to the FIA. Ferrari claims that the component can be classed under the ‘moveable aerodynamics’ catch-all phrase in the regulations, and although it has been discussed in great length over the year it is only now that the Scuderia have chosen to make a formal move against the competition. In this blog post we will aim to cover what the hydraulic heave element does and why a ban at this stage of the 2017 developments could have an impact on the pecking order. Continue reading →
Time to kick this blog back into life a little now that I’m free for summer, and what better a way of doing so than looking at some of the great tech on display at the Goodwood Festival of Speed. This year’s festival was probably the best one I’ve been to out of the four or five times I’ve visited, not least because we had a great spot on the hillclimb to view the cars – on the inside of Molecomb corner along the braking zone right by the hay bales. Mercedes brought the W05 F1 car too, making them the first team to use a new hybrid-era car for demo purposes.
First stop was the FIA stand, which was filled with some interesting information about motorsport in general as well as a few desirable racing cars.
I knew what was going to be on display there, too – the halo concept that F1 wants to introduce next season was the first thing that caught my attention as I approached. Unfortunately, rather than putting in the effort of actually integrating the halo with the car, the structure had clearly been pinched from Ferrari (they tested it pre-season) and quite literally been stuck to an old monocoque.
One of the key design features of this year’s Mercedes W07 is the introduction of an S-duct. The S-duct was first seen in 2012, with Sauber using it as a way to manage airflow over the stepped nose. The idea was that airflow would be less likely to detach from the chassis if air was introduced behind the step. This was done by channeling airflow from underneath the car to a vent exiting backwards above the front bulkhead via an s-shaped duct in the nosebox, hence the term S-duct.
With just two weeks of pre-season testing the teams have had an incredibly tough time making sure not only that their new cars run reliably and that they correlate with what the data has shown back at the factory, but also assessing new components ahead of the first race.
Mercedes covered over 3,500 miles across both tests in Barcelona, putting one of the sport’s biggest outfits in the prime position to try out some aggressive concepts well before the season opener in Melbourne. During the second week the W07 was clad with plenty of complex devices, particularly around the sidepod area.
