If I were teaching a newbie (like sergeant dan who loves to argue just for the sheer sake of arguing because he has nothing better to do with his miserable life) I'd have to simply explain to him that BOTH Newton and Bernoulli are important. Sure, the links you provided above (BTW, good website I refer to it often myself) show that airplanes can fly with the "Bernoulli side" down, however, like I said both Bernoulli AND Newton are important when it comes to explaining how subsonic airfoils create lift. Stop abusing Newton, too! I really wasn't trying to start a Newton v Bernoulli debate. Actually, I think that trying to use either of them to describe lift is a bit like the 3 blind men trying to describe the elephant. I need to figure out a way to write a "circulation theory of lift for dummies" book. The websites I referred to are a bit more like "circulation theory of lift for those who have a somewhat better than layperson understanding of fluid dynamics." One thing ya gotta love about Usenet is that there's a wacko around every corner. OK, so lemme get this straight, mensaboy. According to you, neither Bernoulli -OR- Newton have anything to do with how an airfoil develops lift?? Waiting with baited breath for explanations. This oughta' be good.... No, that's not what I said. Of course, Newton ultimately describes how lift is generated. In a non-relativistic, non-quantum mechanical context, Newton ultimately describes every physical interaction between particles (if you want to break it down tot he level of each particle). You can also apply Bernoulli, once you've descirbed the flow field around the wings. But, ultimately, airfoil designers use circulation theories to design airfoils, because they provide a more complete explanation of why the flow field around a wing behaves the way that it does. Circulation theories are not in disagreement with Bernoulli or Newton; they just give a more complete picture than how Bernoulli or Newton get applied in popular explanations of lift. As far as I've seen (and I requested more information in another post), using Newtonian techniques to describe the "action/reaction", but unless you analyze every little parcel of air effectively solving the Navier Stokes equation for the entire flow field around the wing, it gives you very little insight as to how the "action" gets generated. If I am incorrect on this, please direct me to a good source. And certainly, you can apply Bernoulli, but you have to do a much more rigorous analysis of the flow field around the wing than the standard elementary school "the wing is longer on the upper side, so the flow must go faster to meet up with the flow on the lower side", then apply Bernoulli to this complex flow field. This is why I said that it's a bit like the 3 blind men trying to describe the elephant. Both Newton and Bernoulli are correct (if applied correctly), but do not provide a complete insight as to what the wing is actually doing, and don't provide one with useful tools to design or analyze airfoils. I'm not advocating "Lift Faeries" here. I'm merely saying that the popular descriptions of how lift works don't really give the complete view that airfoil designers use to design airfoils. http://www.av8n.com/how/htm/airfoils.html |

I lost my medical years ago and I never claimed to be a "sergeant pilot" since there is no such thing. Riiiiiiiiight...you couldn't fly yourself out of a paper bag and it would take me only about two minutes to prove it if you dared to show your chicken**** face at my airport. But regardless of the topic, any hooded coward like you, sergeant dan, who trolls and flames people anonymously has ZERO credibility in my book. Thanks for honouring me by using my title. I see that spelling, not unlike aviation, still ain't your forte. Next time you're at the VA hospital picking up your monthly welfare check, Your understanding of VA and welfare are as limited as your understanding of the USAF. It makes me wonder if your father really was ever in the USAF. Frankly, I couldn't care less what you "wonder" about, sergeant dan. You are a nothing, a cowardly netizen nobody who hides behind your AOL pseudonym while demeaning, discrediting, accusing without basis and spouting your bald faced lies. Now, for everyone BESIDES sergeant dan here, Ed Rasimus actually flew CAP during a mission over NVN which earned my Father a DFC. We've talked about this in the past right here on RAM. The award was won in an Oct. 5, 1966, rescue operation in which Captain Marron was responsible for the rescue of two McDonnell F-4C Phantom crew members shot down over North Vietnam. The description of this heroic rescue is discussed in detail in Chapter 16 of Ed's book, "When Thunder Rolled." |

Well marron, it's wonderful that Mr Marron was in a position to and had the integrity and skill to do this heroic deed. I sincerely congratulate him. HOWEVER, I feel that his son certainly isn't living up to the standards that he had apparently set. Doesn't it bother you at least a little that a large group of strangers, most of whom are quite familiar with these aeronautical subjects are comparing the image of your father that you've painted and yourself who has made such a cretinous lout of himself on this ng?. I sincerely hope that there's no mechanism by which he can see the embarrassing image that you've created for yourself here. -- -Gord. |

So Mike your father is a real American military hero while you have done nothing more than "shovel **** in Louisana" and lived in your father's shadow all your life? |
