The Williams
Mercedes FW41 takes to the track at the Circuit de Barcelona-Catalunya as
pre-season testing for the 2018 Formula One season officially gets underway.
This year’s car
features several design changes, some of which are due to regulation changes
such as the introduction of the halo and the removal of the shark fin.
“It’s going to be an exciting year and a great opportunity for the team to
get closer to the front, we believe” commented Williams’ Chief Technical
Officer, Paddy Lowe. “The FW41 is the product of some great teamwork across
the various functions in the organisation, including aerodynamics, design,
vehicle dynamics, race engineering, systems engineering and manufacturing.
The car has many new features, most of which are not all that obvious, but
externally the team has pursued a very different aerodynamic concept which
has allowed us some significant progress in aerodynamic performance. All
Formula One cars are an evolution of what has gone before to some extent,
but the FW41 does involve a number of departures from the directions that
have been pursued in the past.
Overall, the philosophy we are starting to see emerge is a new approach to
aerodynamic development coupled with a new approach to collaboration between
aerodynamics and design to achieve the optimum working result. There is an
obvious growth in devices around the barge board area; in common with our
competitors, this area presented new opportunities in the 2017 regulations
and has been considerably further developed for 2018. There are also a
number of radical changes to the car’s packaging to incorporate further
power unit developments from Mercedes HPP. We had an aggressive programme
but this was a decision we made to ensure we have the quickest car we
possibly can, ready for the start of the season and we are pushing
everything to the limit.”
Dirk de Beer, Head of Aerodynamics, joined the team in February last year
and has been pleased overall with the FW41’s progress. “Comparing the FW41
to the FW40, the biggest difference has been in the approach that we have
adopted, in terms of the aerodynamic development and also the way the
aerodynamic group has worked with the design office. We have taken a more
aggressive approach, both in terms of being prepared to adopt features on
the car which may lead to a loss of performance, but that we feel in the
long term, is the right direction to go, and also being more aggressive in
the way we believe we will operate the car. For example, in terms of how
much fuel we’re running, how much cooling we have in the car. The car is
much less conservative than the FW40.
We are pushing the car to the edge in a whole variety of areas. In terms of
the aerodynamic approach, we’ve moved away from effectively developing the
car with incremental changes from where it was previously, and made some
fundamental architectural changes. What has been nice is that those changes
have delivered steps in performance that we hoped they would. I’m very happy
with the performance we’ve actually achieved for the car. Again, that’s
measured in the wind tunnel and hopefully those results are borne out on the
track. I expect our more aggressive approach will mean that thereare certain
areas where we are going to be a bit closer to the edge and we may have to
do a few remedial actions but ultimately, I think the car is a better
starting point.”
Ed Wood, Chief Designer, added: “The really interesting thing about the FW41
design process is it isn’t just a genesis of a new car, it’s a genesis of a
new team. Some big changes happened over the winter and during the early
part of 2017. We had Paddy, Dirk and quite a few others come on board in
that time. That involves a bit of coming together between people
understanding each other, understanding where Williams’ strengths are, where
the weaknesses are, what the limitations in terms of resource and facilities
are, against the backdrop of all the things you want to achieve technically.
It’s both an interesting and a stretching environment when you’re doing both
things simultaneously. I think the concept of the FW41 is a real synthesis
of what we’ve done well and what was good about the past, and where we need
to go in the future.
When Paddy came here, he recognised that when we moved to the hybrid engines
in 2014, the FW36 was a very strong car, he could see from afar that there
were actually very strong characteristics about certain aspects of that car,
particularly around tyre management, and we’ve drifted away from that with
successive cars until the FW40 last year. There were elements of looking at
the past and we did a lot of development work last year which was focused
around trying to identify the strengths of the FW36 in comparison to the
latter cars and building on that knowledge. So, there’s some FW36 DNA that’s
gone into it, but equally there’s a lot of new thinking that’s gone into the
packaging and the aerodynamics. We’ve been much more aggressive on the car,
we’re opening up a lot of potential for aerodynamic development, so I’m
hoping to see some good characteristics in terms of driveability,
predictability, and the capability of the drivers to get a hold of a good
consistent race car, with a very big uplift in overall aerodynamic
potential. I think that’s what we should see come together in the way the
car’s been approached.
The biggest challenge was timeline as you have a new team of people coming
together, which means new processes and understanding how to work together
to establish. It has been a huge challenge for everyone at the coal face in
design and manufacturing to produce the car from the time that we set the
design direction. The underlying thing is whatever you do it’s the process
of good engineering and trusting in the physics. That’s what we’re doing.
Rather than coming in with a certain set of beliefs, Paddy has come in and
his emphasis is much more on the engineering process and doing the
engineering well. What you’re seeing is a product of it being an engineering
driven car and hopefully its performance is reflected in that.”
Pre-season testing concludes on 9 March before the season officially begins
at the first race in Melbourne, Australia, on 25 March. |
