- Cambered and symmetrical airfoils are two types of airfoils that differ in their shape and performance. A cambered airfoil is an asymmetric airfoil that has a convex upper surface and a concave lower surface123. A symmetrical airfoil is an airfoil that has no camber and has identical upper and lower surfaces123. The camber line of a cambered airfoil is above the chord line, while the camber line and chord line of a symmetrical airfoil are the same13.

Cambered Airfoil: An asymmetric airfoil for which the mean camber line will be above the chord line.www.egr.msu.edu/classes/me440/somerton/Airfoil.…In aeronautics and aeronautical engineering, camber is the asymmetry between the two acting surfaces of an airfoil, with the top surface of a wing (or correspondingly the front surface of a propeller blade) commonly being more convex (positive camber). An airfoil that is not cambered is called a symmetric airfoil.en.wikipedia.org/wiki/Camber_(aerodynamics)For symmetrical airfoils, there is no camber and the camber line and chord line are the same. All airfoils that are not symmetric are cambered, which means that the top and bottom areas are not exactly the same and one surface is more convex than the other.resources.system-analysis.cadence.com/blog/msa… - People also ask

Camber (aerodynamics) - Wikipedia
Camber is usually designed into an airfoil to maximize its lift coefficient. This minimizes the stalling speed of aircraft using the airfoil. An aircraft with cambered wings will have a lower stalling speed than an aircraft with a similar wing loading and symmetric airfoil wings.
An aircraft designer may also reduce the angle of attack of the outboard section of the wings. This ensures that, as the aircraft approaches the stall, the wing root stalls before the tip, giving the ai…Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 3 mins

WEBDec 8, 2017 · 4 Answers. Sorted by: 7. Camber shifts the airfoil's section of lowest drag of the drag polar to higher lift coefficients. In order to create the least amount of drag in level flight, an airplane wing benefits from moderate camber. Most of the lift is created in the mid section, but enough lift is left towards the tips to justify camber there, too.
