The wings of fixed-wing aircraft behave the same way whether they are gliders or powered. Nope. The lift/drag vectors are different as the AOA changes. The rest of Bernoulli/Newton still apply. For helicopter and autogyro blades, the lift/drag vectors are similar except that in autorotation there are propeller and autorotative regions of the rotor. OK, take your workd for it, but I thought Autogyros had pretty much straight blades. Alpha is obviously going to be relative to distance to the hub if the alpha is positive, but even so, you could look at it the same as washout if I'm following you correctly. Bertie They do have straight blades, but the different velocities found at various radii make the difference in AOA at thos points. In forward flight it gets complicated. Here's a good link: http://www.cartage.org.lb/en/themes/...torotation.htm Some helicopters have washout in the blades, but there are still the rotational/advancing/retreating/radius issues to deal with. I find it most amazing that helicopters flew successfully not all that long after the Wright Brothers. The Germans had a workable machine in the late '30s. I thought helicopters were easy-to-understand machines until I had to study them for my AME license. I like complex machinery, and these things fit the bill. I have a little dual in an R44 and have great respect for the folks who fly such ornery animals. Keep ya busy in a hover. Dan |
