The downward velocity induced by the trailing vortex in the vicinity of the wing-tips is called as _____(a) Downwash(b) Local relative velocity(c) Effective velocity(d) Wing velocityThis question was posed to me in examination.My question is from Downwash and Induced Drag in division Flow over Airfoils over Finite Wing of Aerodynamics

Answer»

Right choice is (a) Downwash

The best explanation: The trailing vortices, in the VICINITY of the wing-tips, drag along with them the surrounding air. This INDUCES a SMALL velocity COMPONENT in the downward direction. This is called downwash. NONE of the other terms describe this induced velocity.
