I have personally flown procedures where we hit 100% of the gear loads and the collective pitch stops, while dropping the rotor to the min limit, all at the same time. Not too much left in the aircraft at that point!
...so ya wanna be a test pilot...
I think my students do this on a fairly regular basis.
But onto a more serious question. Is it fair to say that the higher the disk loading, the higher the ROD required to get vortex ring? Is there a reliable corrolation between disk loading numbers and the ROD which will lead to VRS? For instance, will an R44, with a disk loading of around 2.9 lb/ft2 get into VRS at a lower ROD than a Schweizer 333, with a disk loading of around 4.3 lb/ft2? Would any helicopter with a disk loading of around 4.3 lb/ft2 get into VRS at the same ROD as the 333?
