Description

Assuming the Aerodynamic Force Overlay displays forces at point where they act (and the experience suggests it is the case, though I have no undeniable proof) both body lift and drag of fairing (tested on 3.25 m fairing) are applied at the top of, or even in the front of the fairing.

See attached images.

If this is the case, it greatly increases the leverage the force has to affect (un)stability of the ship.

History

#1 Updated by GalFisk about 8 years ago

This explains why some of my fairings were acting completely silly - especially if I made them wider than the base, which made them structurally weaker.

There was much celebration when this was fixed in 1.1. I'm quite confident this one is now resolved, but just to confirm I've attached ksp-bug6779.png showing correct fairing body lift placement under v1.1.3
