www.dept.aoe.vt.edu6. Airfoils and Wings The primary lifting surface of an aircraft is its wing. The wing has a finite length called its wing span. If the wing is sliced with a plane parallel to the x-z plane of the aircraft, the intersection of the wing surfaces with that plane is called an airfoil. This airfoil shape can be

Principles of Flight: Foam Wing (Grades K-12)
www.nasa.govflow airfoils were originally developed to make an airplane fly faster. The laminar flow wing is usually thinner than the conventional airfoil, the leading edge is also more pointed, and its upper and lower surfaces are nearly symmetrical. However, the most important difference between the airfoils is that the thickest part of a laminar

Axial-Flow Compressors
www.netl.doe.govSince airfoils are employed in accelerating and diffusing the air in a compressor, much of the theory and research concerning the flow in axial compressors are based on studies of isolated airfoils. The nomenclature and methods of describing compressor blade shapes are almost identical to that of aircraft wings.
