LoginThe NACA LS (1) – 04XX airfoils when compared to NACA airfoils with same thickness had higher L/D ratios. For a lift coefficient of 1.0, what was this increase approximately in percentage?
(a) 80%
(b) 20%
(c) 50%
(d) Less than 10%
This question was posed to me in unit test.
I need to ask this question from Modern Low Speed Airfoils in portion Incompressible Flow over Airfoils of Aerodynamics
Aerodynamics Incompressible Flow over Airfoils in Aerodynamics 3 years ago
The correct answer is (C) 50%
For explanation: The LIFT COEFFICIENT of 1 is VITAL for the aviation sector. The new low-speed airfoils developed had higher L/D ratios. For a lift coefficient equal to 1, the increase was about 50%.
