Ferrari brought a couple of small updates in Korea all
targeting rear downforce. They also tested an older rear wing, used in Belgium,
which features only two gills on the endplates. The certain rear wing was also tested in Japan. The reason, is simply because of the nature of the Korean track
which has 3 long straights at the beginning and then fast flowing corners for
the rest of the lap, so Ferrari tested both a high and a lower downforce setup
but at the end they opted for the higher downforce one.
The first small update is a new fin on the front brake
ducts (highlighted), aiming to produce a vortex and improve flow towards the rear of the car.
This shows the complexity in design of today’s F1 cars, as s small part on the
front of the car actually affects the rear.
The other two updates are actually parts raced
in previous races which had been replaced with ‘upgrades’. Reverting to the
older parts though suggest that they weren’t really upgrades but maybe
downgrades. The first of the two are the vortex generators below the wing
mirrors introduced earlier this season (1st drawing) but were later
modified by attaching the mirror to the one away from the driver in order to
reduce the strength of the vortex it produced (2nd drawing). This
weekend though they reverted back to the older design (1st drawing).
These two vortex generators induce vortices to help direct the exhaust plume
down towards the diffuser.
The other update is to the diffuser’s footplate. Again this
small tunnel on the footplate (1st drawing) was introduced earlier
this season to push the exhaust plume down inside the diffuser to energize the
flow, but was then removed as an ‘upgrade’ as Ferrari’s CFD and wind tunnel
test deemed it unnecessary (2nd drawing). This weekend again though,
they reverted back to using it.
Both of the later two updates are just another confirmation
Ferrari has been experiencing wind tunnel problems.
Hi,
ReplyDeleteIs it true that Alonso and Massa used different exhausts during the race?
Thank you
Hello,
ReplyDeleteno it is not true! it was a wrong translation of the article from Italian IICRC to English! The article said that Massa had a new small update in Korea (which we don't know if it is true) and that there would be a new exhaust configuration in India!
Looking at the photos I saw no differences.
ReplyDeleteThanks for your clarification
Regards
Appreciate you blogging thhis
