Hiya Lonewolf. You must be a helicopter pilot. Twerp the Swiss plumber hisself, Bernoulli, what used the term, Inviscid. He was a contemporary of Bram Stoker, so may heap he coined the term in honor of some bloody beast. He used the term to describe....air. Not solid, no viscosity. He opined that at the velocity of 266.377 knots, air became compressed to serve as a foil on a par with liquids, and solids....I think.
Yes, a wing is acted upon with a push, there is no such thing as a pull in nature, nor is there "vacuum". Differential pressures, SI.
Thrust is what we want, there is no pull, push is what keeps us airborne. Jet, prop, farts, it's all thrust.
Helicopters fly by converting vibration into fear, which levitates the machine and it's contents. Or summat.
