aerofoiln.

Brit.

/ˈɛːrə(ʊ)fɔɪl/, U.S.

/ˈɛroʊˌfɔɪl/,

/ˈɛrəˌfɔɪl/

Origin: Formed within English, by compounding. Etymons: aero- comb. form, foil n.¹

Etymology: < aero- comb. form + foil n.¹ Compare later airfoil n.

1. A structure or surface having a profile that provides lift at right angles to its passage through the air; esp. a wing, aileron, tailplane, or elevator of an aircraft. Also: a structure designed on similar principles, as the blade of a propeller or the sail of a wind turbine, which converts torque into thrust or vice versa.

1907 F. W. Lanchester Aerodynamics v. 179 The author does not employ the term aeroplane outside its correct signification, that is to say, to denote other than a true or plane aeroplane; the misuse of the word being avoided by the introduction of the word aerofoil, to denote a supporting member, or organ of sustentation of undefined form.

1920 Flight 12 1301/2 Balsa wood..is so extremely light that it can be recommended for making aerofoils.

1966 D. Stinton Anat. Aeroplane v. 58 To generate a given lift at a given airspeed an aerofoil of long span has to impart a smaller downwash to the air it meets than an aerofoil of shorter span.

1990 T. Cunliffe Easy on Helm vi. 49 If the wind is on the quarter and you sheet it hard in, it will no longer function as an aerofoil.

1998 Skydiving June 15/1 Most canopies are designed to provide most of their lift in the front third of the aerofoil.

2002 New Scientist 1 June 22/3 The aircraft relies on lift from a tailplane and from stubby aerofoils called canards mounted on its nose.

2. A similar but inverted structure on a motor vehicle designed to enhance road-holding.

1966 Motor Sport Mar. 182/2 In 1956 two young Swiss engineers, Pierre and Michel May, built an adjustable aero-foil wing across the top of their open Porsche Spyder, and this could be tilted..by means of a lever.

1989 Pract. Caravan Sept. 10/2 The aerofoil at the front has also been moulded to make the shape both more stylish and aerodynamic.

2001 J. C. Grimwood Pashazade (2003) xxviii. 154 A speed-tuned aerofoil in the nose and a fixed diffuser tunnel at the rear kept the wheels glued to the road.
