Re: Archie a non-flyer? (was:Re: origin of bats/reply 2 to TMK)



but Bernoulli works if you want to put the effort into it.

Not to create the most of the lift (perhaps in some special circumstances).

I think you have misunderstood the situation here a bit. The aerodynamic forces on a wing are produces by the fluid flows - these flows can be modeled in a few different ways, and the Bernoulli model is one of them. However, using a Bernoulli model turns out to be quite clumsy and difficult for most real wings with any level of complexity, and so a vortex model is generally preferred. It's a difference in models, only - they are not distinct effects.
