File:Examples of Airfoils.svg

English: Selected airfoils in nature and various vehicles, with their approximate chord length indicated.

Sources for the shapes of the airfoils:

• Low-speed ULM wing: drawn over own photo of low-cost, low-speed ultralight

• Propeller blade: drawn over own photo of a sliced WW2-era bomber propeller

• Airliner: Profile of an A-321 wing at root, as represented in Bertin 2009^[1]

• Supersonic interceptor: Profile of an F-104 wing at root, drawn over own photo of a wing section exhibited in the Deutsches Museum

• Blackbird : as shown in Alexander 2002^[2] (very approximate drawing on original, chord completely estimated)

• Dragonfly: loosely interpreted from data, photo and diagram in Hertel 1966^[3]. Section roughly mid-wing.

• Dolphin flipper fin: drawn based on CT scan shown in Fish & al. 2008^[4], chord estimated.

• Sailboat mainsail: Drawing based on own knowledge & observation.

• Turbine blade: Drawing based on multiple representations in aeronautical propulsion textbooks.

• Turbofan fan blade: Drawing based on own knowledge & observation, inspired from Rolls-Royce 2005^[5].
