The prop spins without touching the shroud. Are you saying the shroud should be bullet-proof, able to withstand a catastrophic failure of the prop?

In order for a shroud to improve thrust, there has to be super precise tolerance on the blade to shroud clearance.
Actually, the ducting-trust-improvement was a secondary possible benefit of the shroud, but I'm certainly interested. Do you have any information on the effect of varying the size of the margin between the inside shroud diameter and the prop diameter?
