Wake turbulence and WW2 bombers
« on: March 09, 2017, 01:51:25 PM »
Watching this video about wake turbulance of relatievly small An-2 aircraft: https://www.youtube.com/watch?v=KXlv16ETueU

I wonder... how could pilot of relatively small plane like 109 sit on tail of huge aircraft like B-17/24 and shooting accurately without being thrown away

A part of the answer is Angle of attack. The heaviest vortexes are produced at high AoA on take off and landing, not at cruise speed.

and wing tip vortices (wake turbulence) by nature, tend to descend behind and below the aircraft creating them.

But I have read accounts by German pilots of being thrown off course, or off mark, by the wake turbulence, so it was there.

Flying into your own wake doing a 360deg turn should avoided in ultralights/VLA, when you do it you know why.

The biggest bump is behind and below the wingtips. When getting in tight on the B-17 with the B-24 I knew I was about right when I could feel my wingtip get pushed up a bit by the vortices off the Fortress.

I've been directly behind the B-24 in the B-17 very close and felt nothing.  We closed to within 10' or so.
