Finding Airfoil Data For Amateur Projects?
An anonymous reader asks: "I am an aerospace engineering student who is engaged in an amateur project. A major hurdle I am having is finding modern airfoil data which can be used for a non-profit project. As most aerospace engineers know, just about all modern airfoil data are guarded industry secrets, so building an amateur project that requires precise airfoil data is difficult, because of the lack of available modern information. There is plenty of dated airfoil data from the 1960s or earlier, but my project requires access to modern data. Note that I do not have access to a wind tunnel to procure this data on my own. Where would one find free modern airfoil data for use in an amateur project?"
Sorry, "the rest of the world"? Most of the rest of the world doesn't speak English. In the English-speaking world, most native speakers are American.

Aren't most English speaker from India?
I was specifically talking about native speakers, where the answer is most certainly no. http://www.ethnologue.com/show_language.asp?code=E NG gives the totaly number of native English speakers as 341 million as of 1999. It's safe to say that the US, with a population of 290 million, contains a comfortable majority of those. That same site gives the total population of English speakers, native and non-native, at 508 million, and I think the US gets a majority even there.

Like others have said consistency is very important. When I go to Dunkin Donuts I know what I'm going to get. (although the service sucks) Customer Service is just as important. Experience what the customer experiences! Call your own phones to see how you are treated... Order your own products to experience the experience. This will tell you how your customer feels. I can't count the times I've had rude or unhelpful customer service reps.
Good luck...
