Wake Turbulence behind an A-380
"Jay Honeck" wrote in message
"will descend further and be significantly stronger" than those from other large jets, potentially even affecting jets traveling in the opposite direction some 2,000 feet below. Who's authors haven't heard about RVSM- ICAO's or WSJ's? D. |

Wake Turbulence behind an A-380

I would partially disagree in that he minimises viscosity of the air as a factor. True it is small, however if the air had no viscosity then there would be no circulation and hence no lift. He actually shows diagrams without circulation which produce no lift. The necessity of viscosity was demonstrated by Jean le Rond d'Alembert. In fact he did painstaking mathematics, without recognising viscosity, and failed to be able to show why there should be any forces on a body in an airflow at all. He went to his grave a puzzled and dissatisfied man. That is d'Alembert's Paradox. -- David CL Francis |

Wake Turbulence behind an A-380
I know the jet you're referring to but can't remember it... however, I
do also remember that Herb Baker's T-28 has exactly the same system and you can see a video of it he http://herb-ditto.com/Herb.wmv It makes for a very cool display. |
