Consider a simple prop plane like a Cessna. I'm a little confused about the origin of the energy for lift. We know the engine accounts for all the thrust and the wings have drag that varies by angle of attack, which also changes lift. But does the engine account for all the energy in lift? If not from where does the extra energy come? It seems there's some basic concept in Bernoulli's Principle that I may be missing here.
Please advise or suggest a good link, book, or anything. I'm more than willing to read more but what I've found doesn't answer my question.
