F1 tech­ni­cal fo­cus

Autosport (UK) - - CONTENTS - GARY ANDERSON

The brake-duct siz­ing is a com­pro­mise. You gen­er­ate most heat in the brake by brak­ing from high speed to low speed, so you need de­cent air­flow at low speed. But it will not be able to take all that vol­ume of air at high speed and the ex­cess will spill around the outer sur­face.

This small turn­ing vane just be­hind the ac­tual brake-cool­ing in­let will just be man­ag­ing the ex­cess air­flow that comes around the outer sur­face of the duct.

The lower hor­i­zon­tal turn­ing vane, which in ef­fect puts an end­plate on the ver­ti­cal turn­ing vane it’s at­tached to, gives a more con­sis­tent air­flow com­ing off the trail­ing edge of that com­po­nent – es­pe­cially with vary­ing steer­ing lock.
