Visit here:
Does lift go up in Ground Effect? - Jetcareers if you have further questions. Competent open-minded long time members, not arrogant, close minded attitudes.
Ryan, you believe your knowledge has reached its peak, that your concepts are fact. You refuse to see that you may have misunderstood a certain aspect of what you were trying to explain.
Instead of accepting this possibility, you ignore it and argue random topics, and introducing unnecessary information to beef up your, lack of an argument regarding your fallacies. I am not saying you are all wrong!!! You are likely a brilliant person, which makes you more susceptible to these "my word is law" beliefs. But instead am saying, your ideas need work, they are far from perfect, law. Until you accept that, you will cease to learn any new information, good luck I am done here.
This has turned into an ad hominem argument.
'Close minded and arrogant' are attacks on the person presenting the argument.
I don't believe for one second I'm at the "peak of my knowledge" or that "my word is law" - this again is an ad hominem (which is a logical fallacy).
If you have a problem with me personally, feel free to PM me - I just don't think that a public forum is the place to call people names and psycoanalyze.
It is also bad form to effectively bad mouth someone at another forum.
Attack the argument, not the person.
We are simply talking about a phenomenon, a rather deep topic infact.
We can all be civil here, if there is something that you believe I've said in error -specifically- please feel free to point it out, and I'll do my best to defend or retract what I've said and give a reference based on a systematic opposing response/post.
Perhaps we agree to disagree.
On a more post specific note, I agree with you that there has probably been a lot of useless (and otherwise confusing) information (especially pertaining to Bernoulli) - but my point was to show that the very basic lift equation begins at F=MA - all others hold that at the core. And to answer a fellow at your other forums, yes indeed, Bernoulli's principle has become controversial lately as applied to aerodynamics (since it applies to hydrodynamics - or incompressible fluid). Bernoulli's principle is an example of the conservation of momentum though... so my (unsuccessful) purpose was to tie this to how a vortex affects each part of lift, and how the lack of a vortex affects the overall energy.
I've started to trace back through my old engineering books to better explain the relation at some point in the future.
