Somewhat surprisingly, it shows that even in level flight and climb at certain
speeds, these helicopters produce blade slap. This is probably due to the region
of upwash at the front of the disc which makes the tip vortices generated in this
region ...
It makes no allowance for the obvious possibility that the vehicle might be flown
