Been doing a little lunchtime reading, and i'm actually quite impressed with the level of thought that has gone into this concept. I'm still not entirely convinced that rigids aren't a better rotor system than teetering for high mu, but Carter have certainly done their sums. The mu=1 out of track divergence is a concern, since it suggests that some instability is inherent.
I'll watch this project with interest.
MickJoeBill,
I actually spent some time as a crash engineer (Rover 75 mostly), before i answered my natural calling in powertrains
. Agreed that the most important thing in a crash is for the structure to protect the occupants from the powertrain. As to the rest breaking away, well whatever method absorbs the energy to provide a continous decceleration from impact start to finish.
