Analysis: 2018 Halo and its performance implications

Right, hello everyone. You may have noticed a few other posts pop up on here lately but this one is by me again. I, like many of you, was not happy at all when the FIA announced that F1 would be adopting the Halo cockpit protection device from 2018 onwards but no doubt I’ll continue watching next year…

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.

Analysis: F1 Suspension Geometry

I’ve talked a lot about the aerodynamic and power unit components of a Formula 1 car on this blog, but rarely touched on the raw mechanical systems that are also critical to performance. There’s a reason for this, though – it’s all a bit voodoo. There are plenty of theories behind proper suspension geometry for a race car, however it becomes much more complex to analyse these mechanics at F1 level as downforce – the biggest performance differentiator in the sport – plays an important role in the design calculations.

For this blog post I am going to run over some of the important aspects of suspension geometry and the factors involved (e.g. centre of gravity, aerodynamic downforce). Continue reading
