DeltaV By Seated Position on Rotating Offset Frontal Impact

[MSI]

We split off as a separate this topic since it relates to a couple of threads, in particular

• forum topic DeltaV/Accel at location other than CG?

In response to a question on one of our video on the Princess Diana crash a question came up on the relative Impact Speed change (DeltaVs) by location for an angled offset crash.

• The following was a response posted to our Princess Diana Crash reconstruction Thread. We created this msmac3D crash reconstruction video of an angled offset crash similar to the Princess Diana Crash:
  • Note this is also covered on forum topic Princess Diana Crash Reconstruction
  The msmac3D summary is as follows:

  and the summary of the smacthp DeltaVs from the msmac3D crash reconstruction:
  
  • Note that the msmac3D convention for X,Y,Z coordinates per the aeronautical sign convention (Z positive toward the earth!) (not cartesian (Z comin at you from your screen!)
