Development Methodologies for Formula One Aerodynamics

Article of Honda R&D Technical Review F1 Special (The third Era Activities)

Summary

The greater part of aerodynamics-related development for Formula One involves optimization using objective functions of downforce and the lift-drag ratio (L/D), and verification of effects using wind tunnels and CFD in the development process. As examples of development methodologies used to advance this optimization process, this paper will discuss aerodynamics development tools, including wind tunnels and CFD, and the conventional development indices that employed these tools. In addition, the paper will introduce new indices for analysis of the effect of tire deformation on the aerodynamic load and analysis of transient aerodynamic characteristics during deceleration, and will also consider the findings made regarding air flows using these indices.
