I'm a computer scientist that likes to read about math and physics occasionally. A local author at a nearby aviation center brought bernoulli's flight equations into question.
It was clear enough logic, but I didn't understand all the math involved. He basically said that the lift equations don't account for why a plane can have lift while it's still upside down and took some sample data on his small aircraft to show.
Anyhow, I didn't know what to make of it, my only point of view and my first acquaintance with flight physics.
How much effect does Bernoulli's equations play in flight, especially when an aircraft is upside down?
He suggested that Newton did some early work on lift equations, is this true?
What is a sufficient way to view Bernoulli's lift equations?
