Title: FIA regulations - Aerodynamic Stability
Post by: TrickyDicky on January 03, 2018, 02:21:42 PM
In the "2018 APPENDIX D REGULATIONS FOR LAND SPEED RECORD ATTEMPTS", the FIA has given 12 months notice of the introduction of new regulations that will apply from 1 January 2019 onwards.  These affect vehicles capable of more than 550 kph (about 340 mph).

ARTICLE D1 ELIGIBLE AUTOMOBILES

D1.1.5 Aerodynamic Stability.

D1.1.5.a Automobiles conducting Record Attempts where speeds between 550-800 kph are anticipated must show the Centre of Pressure (CP) in yaw and pitch and Centre of Gravity (CG) relationship for the automobile, with a brief summary of the method used to measure it.

D1.1.5.b This information is to be submitted to the FIA as a supplement to the registration form for the Record Attempt. Automobiles that have previously participated in an FIA Record Attempt in this speed range are exempt from this requirement, but must provide proof of that participation with the registration form. The FIA reserves the right to require a more detailed stability analysis, after a review of the provided summary and the methods used.

D1.1.5.c Automobiles conducting Record Attempts where speeds are anticipated above 800 kph must show the CP in yaw and pitch and CG relationship for the automobile with a full supporting aerodynamic analysis. This information is to be submitted to the FIA as a supplement to the registration form for the Record Attempt.

D1.1.6 Braking. Automobiles conducting Record Attempts where speeds are anticipated above 550 kph must show an analysis of stopping distance for any speed regime in which the car will be run. This information is to be submitted to the FIA as a supplement to the registration form for the Record Attempt. Automobiles that have previously participated in an FIA Record Attempt in this speed range are exempt from this requirement, but must provide proof of that participation with the registration form.

D1.1.7 The competitor is solely responsible for the integrity of the information provided to the FIA.
