My study of aerodynamics thus far indicates that it is impossible, unless you
descend to catch your descending wake. Wakes _always_ descend. It's a
consequence of the mechanism that produces the lift that sustains the
aircraft, and it's unavoidable. Every source that I have consulted points
this out, without exception. Your mere assertion to the contrary is
completely unpersuasive in comparison.
My only comment on this subject - I'm not going to bother arguing
about it, as 1) according to the aerodynamics, it definitely IS
possible to fly through your own wake turbulence in steep turns, and
2) like most people who have actually done steep turns in a real plane
in calm air, I've done it.
Tip vortices (the major part of wake turbulence) extend outward and a
fair distance UPWARD from the wingtip. As well, since the plane is
banked in a turn in the described situation, the vortices descend at a
much slower rate than they would for S&L flight. A simple search will
reveal several NASA and other studies with graphics and photos
depicting an aircraft flying through smoke and the resulting tip
vortices. One of the photos that is in a few studies shows a small Ag
plane, with the upward spiral of the tip vortices reaching 2-3 times
the height of the aircraft, and outward from the wing by half a
wingspan, near the ground. As ground effect decreases the vortices,
at altitude they can be larger.
It just means you don't know a whole lot about real flying or what
happens in a real airplane.
No, it means that I look at the facts, and I don't depend on the legends.
Then you haven't found all of the facts.
Have you ever done a short field take off in your Flight Simulator
Cessna with the springy gear and had the mains vibrate for a few
seconds shaking the airplane?
I don't fly the Cessna, and I fly only at airports with hard, smooth runways
that won't bounce the aircraft around.
Planes bounce just fine on hard, smooth runways - ask any pre-solo
student.
