LoginIs symmetric airfoil produce positive lift?
(a) False
(b) True
The question was posed to me in a national level competition.
The question is from The Symmetric Airfoil in chapter Incompressible Flow over Airfoils of Aerodynamics
Aerodynamics Incompressible Flow over Airfoils in Aerodynamics 3 years ago
The correct option is (b) True
Best EXPLANATION: A symmetrical airfoil only produces positive LIFT, when it is at a positive ANGLE of attack that is leading edge is higher than the TRAILING edge. The air stream splits between top and bottom at the STAGNATION point which is in front of and below the Centre of nose radius.
