Article C13.4.9
Engine Separation
Chapter: C13.4
In Simple Terms
Teams must prove through testing and calculations that if the engine starts to break away from the car's safety cell, it won't cause the entire structure to fail dangerously. Engineers keep increasing the force on the engine mounts until they break, then repeat the test by removing each broken mount one at a time, until only two attachment points remain working.
- Teams must mathematically demonstrate that engine separation won't cause catastrophic structural failure
- Testing involves progressively increasing loads on engine mounts until failure occurs
- Analysis must be repeated for each failed mount, continuing until only two mounts remain functional
- This ensures the survival cell maintains integrity even if engine mounts are severely damaged
Official FIA Text
Must demonstrate by calculation that engine separation from Survival Cell does not cause significant structural failure. Load applied through engine mounts increased until failure, with analysis repeated disconnecting each failed fixing until two remain.
