Why wingtip vortexes can aid flying of the hind birds?

Question

Birds fly in V-shape in order to save energy from the vortexes produced by the front birds. How do the vortexes create uplift thrust?

Answer 1

The votexes spiral or corckscrew as they trail from the wing tip. The air is spilling from the high pressure under the wing in an effort to equalize with the lower pressure on the top.

Each vortex is spinning in a circle when viewed end on... Depending on your location on that circle there will be an updraft, down draft or cross wind component. The direction of the spinning depends on which wing you look at...

Answer 2

wingtip vortices (if we can talk of wing here) of MiG 21 have been reportedly waiting to show the unwary wingman 180degrees. be conscious it incredibly is a similar classification. having gentle after heavy, you've difficult time improving your nonaerobatic cessna appearing its first 0.5 roll (chop up S) in its carreer. to not point out the feds who probable could be drawn to WHY have you ever carried out a suspected close to omit with that airliner. i've got been onboard on a similar time as we had encountered our very own wake turbulence /approx 4,5tonnes helicopter on the time, appearing tight turns/ it incredibly is critically bumpy, extraordinarily in case you do not assume that. we had an incident on our base, while a Mi 24 escorting a Mi17 from a project crossed the song at the back of the Hip, on a similar time as the two helicopters have been already interior the hover section (shifting forwards at approximately 30 KTS and slowing, the Hind approximately 600 ft at the back of.
