RE: The Physics of Flying
This thread is about aerodynamic schooling. I challenged it's merits in terms of both time expended and also in terms of practical, real world application.
A speed contest between two .061 [1cc] powered planes is the purest, most basic form of practical knowledge applied...NO...? There is only the stop watch, the doppler recordings and the onboard telemetry to dispute....no judges, no politics, no white loafers and no "Team Futaba" shirts. If 1cc is too small for you, then we could shift up to 6.5 cc [.40] size. That would UP the ante though. |
RE: The Physics of Flying
John Anderson texts are some of the best out there. Fundamentals of Aerodynamics is probably the most widely used text and is enjoyable to read. You may be able to find an old edition for $30-40.

Does castor oil have anything to do with it? Well, yes it does, see how the physicists squeak when they don't get enough!
Actually, I wish to add another very good source of information. This is about full scale, but the physics are the same. Very helpful to me. http://www.av8n.com/how/ Bedford |
RE: The Physics of Flying
Do the classic aerodynamics physics account for the fact that you can not scale down gravity, air molecules or time with miniature airplanes...?
Those books still say that deltas need special airfoils with reflex to fly level....:eek: |
RE: The Physics of Flying
If you are trying to understand it at the mathematical level:
anyone who starts out with F=MA stay clear, they will bore you with their highschool physics and mislead you with ignorance. Not saying f=ma is wrong, but its way way too simplified to even come close. You will need a solid understanding of differential equations which requires strong algebraic and calculus skills. Any other way is hand waiving and not a real solid understanding of anything. |

Whichever direction the Department of Aerospace Engineering, University of Illinois at Urbana-Champaign is. http://www.rcuniverse.com/forum/js/f...wink_smile.gif Spend 4 years there. Whatever you do do not take seriously any information from the myriad of "experts" in any hobby forum. http://www.rcuniverse.com/forum/js/f...spinnyeyes.gif

RE: The Physics of Flying
ORIGINAL: Steve Steinbring You can stall an airplane at any attitude, at any airspeed, when you exceed L/D max which is the lift to drag ratio! <br type="_moz" /> |

ORIGINAL: Old Fart If you're just beginning,and a bit nervous,it could mean whats IN the seat of your pants..that don't smell much like castor oil:) Jeesh, a guy asks a perfectly askable question and some ofthe answers discuss the physics of loaded diapers. AMAZING....some folks have entirely too much time on their hands |

ORIGINAL: combatpigg This thread is about aerodynamic schooling. I challenged it's merits in terms of both time expended and also in terms of practical, real world application.

If 1cc is too small for you, then we could shift up to 6.5 cc [.40] size. That would UP the ante though. But I do agree that aerodynamic schooling can only get one part of the answer - practical experience gives the rest and that is where the ART comes in. But don't mistake ART in one area (speed or power) as having complete practical knowledge of flying. |

It's a nice, simple opportunity to demonstrate how a classically trained aerodynamicist should be able to blow the doors off some bumpkin who got his knowledge off the back of a Wheaties box. Don't you think so..? |

RE: The Physics of Flying
Well there are a plethora of AMA formula speed events that await new designs gleaned from the back of a Wheaties box. If you truly got game, prove it there. Pylon has the saying "When the flag drops, the BS stops".
|
RE: The Physics of Flying
Pylon is a flyer's event. Straight line speed has more to do with the plane's design superiority and less about the pilot's ability to line it up for a timing pass.

RE: The Physics of Flying
Ok. This has gone from a question about dynamics and physics of flight to a down-right bar-fight. So say good night, Gracy.
