"bernoulli" sounds conventiently scientific to explain lift, but it ain't real. Because the wing is moving in relation to the air, it is continuously "yanking the floor out" from under its current air column, thereby generating a continuous lifting force. Each person can visualise the causes of lift the best way it works for themselves. I can understand completely what you're saying, and it's a nice simile. Like all similes, it's incomplete, but that's irrelevant for sailors and pilots. Brian Walcott in his 1 Apr post gave an excellent, more thorough and technical description of the various elements of cause and effect when creating lift. I would guess he teaches fluid dynamics. Jax has been trying to say that you can create lift (low pressure over a wing) without causing air (in that low pressure) to speed up, and later, without causing air to move downwards. Rather than just telling him he's wrong, I've been trying to show him that his statements are inconsistent with with the laws of physics. So far he hasn't responded, apart from saying 'nah'. JimB |
