Downforce Generation Design

In this blog we will be looking at and analysing the famous Formula 1 Ferrari 312T. Using bramble to run high fidelity CFD simulations and anaylsing the results. 

During the 70’s era, devices to generate downforce became an increasing trend on F1 designs due to the performance gains obtained. The Ferrari 312T follows this featuring a single element front wing and a double elements rear wing, with the objective of generating front and rear downforce to the vehicle.

CFD results of Ferrari 312T

The front wing is composed of a high-cambered full-width single element, covering the nose section. It manages to generate low pressure on the underneath surface, but it is also showing trailing edge separation along the span wise after the mid-section.

 

The rear wing has a double element configuration positioned slightly above the rear tyres height. The flow remains majorly attached besides the centre section, generating high-levels of downforce and an upwash on the wake.

 

As you can see from the images, the front brake-ducts provide increased airflow for the cooling of the brakes.

Downforce & Drag Sources

The largest downforce contributors on the Ferrari 312T are the front and rear wings devices, accounting for 84% of the total, resulting in an aero-balance of 10.85% at the front and a drag to lift ratio of 1.17.

 

The largest drag contributors are the exposed wheels with 31% and the front and rear wings, with a combined contribution of 27% due to the lift induced drag.
