And back to the subject of books.........

As BMatthews says, there are pages in the Theory of Wing Sections that are quite instructive. I found that the math wasn't actually of much value to me, but the general presentation was very worthwhile. There is a section on the Theory of Thin Wing Sections for example. It's quite interesting to note how much is actually known even if it's not showing up on C5Bs or F-22s nowadays.

What is of unique value from this book are the many charts that compared actual test results versus the theoretical predictions. But sections like the High Lift Devices section were the most useful. The book seems to document a lot of the low speed research being done at the time. And that means it covers a lot of what we're interested in right now. The numbers and equations really aren't of much value, but the comparisons and relationships certainly are valid. And a lot of that information is shown in charts.

It'd be worth having.
