Pressure Bubble Myth

Southernweyr

Q1. Bernoulli : right on, at same trust levels, the pressure above MR proportionally increases with the pressure below when induction speed (and induced drag) decreases

Q2. I claimed the opposite, IF the grass slows down the outflow it may reduce induced speed, so I claimed a few feet higher hover when compaired to sleek concrete, but this is SPECULATIVE, as some pointed out I don't model this with CFD, so need to rely on experimental data. I observed this experimentally but not using a scientific set up.

Q3. Indeed, I claim that from 8-12 knts onwards indeed no dip will occur, starting at lower headwinds, a dip should occur
