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
However I’ve come to accept that the sport must do everything it can to improve safety (especially in the wake of Jules Bianchi’s accident) and decided to do an assessment of how the Halo will impact the cars both visually and from a performance standpoint.
Now, there are a few things you might have missed about the implementation of the device due to the red mist descending. Firstly, the teams can paint the ‘flip flop’ in whatever colour they like and secondly, and most importantly, they are allowed to wrap it in a 30 mm fairing to tidy up the air around it. Considering that the Halo is in the firing line of freestream flow around the airbox, the structure mostly hinders the intake of clean air to the ICE, cooling and flow to the rear wing. Other side effects include at least 20 kg extra weight and possibly some disturbances to the air over the sidepod.
The Halo’s basic design will be refined by the FIA between now and the start of 2018. In testing teams have pinned it to the tub in different ways, some slightly better looking than others. Whether every team will have to fix it in the same position remains unknown. The small fairing does however present some opportunities to shape airflow in a more desirable way, although they won’t want too bulk up the tubing much more to reduce blockage and thus decrease drag.
I don’t know about you but since the news that Red Bull’s F1 design guru Adrian Newey was teaming up with Aston Martin for a ‘new project’, I’ve been waiting with bated breath for what kind of machine the two could produce together. Despite the lengthy wait, nothing could quite prepare any of us for what we saw when the AM-RB 001 prototype was showcased in early July.
Once launched the codename will be changed to something more elegant (and probably beginning with a ‘V’) but no doubt the bold body shapes that make it the eye catching will remain. It’s a little Marmite (personally I love it) however every carbon fibre-formed surface has been meticulously sculpted on CAE software to produce a car that meets Newey’s intense focus on aerodynamics.
