So long ago for me that it strains the memory and I dare not comment. I recall doing this stuff over 50 years ago and then more fancy stuff:
Subsonic Aerofoil and Wing Theory | Aerodynamics for Students
I amuse myself these days by helping some with the "
cesspit of misinformation, half-baked truths and misshapen facts" mentioned in
https://www.flightsafetyaustralia.co...y-unteachable/ Unfortunately it is the regulator which is often the root cause of it. Incidentally, I don't mind them calling me a dinosaur. Aerodynamicists these days tell me that my CFD wasn't really CFD (stretching the capability of mainframe computers back then). CASA's current Flight Instructor Manual is pretty much the same as the 1967 version at the time I was doing my flight training. I've learnt a lot since.

So much for lift generation .... Force can only be applied to an object immersed in a fluid by changes in pressure of the fluid in contact with the body. ... The distribution of those pressures and forces is best calculated using Bernouilli’s theorem ... That covers Bernoulli
That's it really
Sums it up nicely.
