FW SLM Actuator Aperture

Chapter: C3

In Simple Terms

Teams are allowed to have small openings (apertures) in the front wing or nose for the steering linkage mechanism that moves the wing. These openings have strict size limits and can only rotate within a 10-degree range in each direction to prevent unfair aerodynamic advantages.

  • Aperture must fit within a defined 20x20x120mm box with 10° rotation limits in all three directions
  • The opening can only be as large as necessary to accommodate a 5mm offset of the steering linkage's swept movement
  • Located on Front Wing Bodywork or Nose assembly only
  • Designed to prevent teams from exploiting the aperture for illegal aerodynamic benefits
