Photographic evidence WebJan 21, 2024 · In the wake of of a lifting surface, you'd inevitably find vortices. Even if a body or surface is non-lifting, vortices will also be present in the wake due to the shearing effect of friction, which causes fluid elements to rotate and generate vorticity, unless we are in an ideal inviscid flow. Eddy

WebThe vortices create air inlet distortions that disrupt temperature sensing and cause mild instability in controlled speed so we need to get rid of them. Likewise when beginning a takeoff roll most pilots bring power up gradually until some airspeed develops then can “punch” it down the runway. WebSeen from behind, this vortex is rotating anti-clockwise. When the left wing of the follower first enters the vortex, there is on this wing a local angle of attack increase and therefore the lift becomes higher than on the right wing. The initial roll motion is therefore to the right.
