ANNEX VIIIVERIFYING AIR DRAG DATA

F1Appendix 9

Input parameters for the simulation tool

Introduction

This Appendix describes the list of parameters to be provided by the vehicle manufacturer as input to the simulation tool. The applicable XML schema as well as example data are available at the dedicated electronic distribution platform.

The XML is automatically generated by the air drag pre-processing tool.

Definitions
