The chord line cuts the airfoil into an upper surface and a lower surface.

English

Subject field(s)
  • Skydiving, Paragliding and Hang Gliding
CONT

The colorful cloth that suspends us is known as the canopy or wing. There is an upper surface and a lower surface to this canopy as well as a leading edge and trailing edge. The upper and lower surfaces are held together by ribs that are shaped to create a cross section like a bird's or airplane's wing.

CONT

The canopy is constructed of a top and bottom surface joined by a number of vertical segments. When it is fully inflated, the cell takes up an aerofoil shape with a flattish lower surface and a curved, or cambered, top surface.

Record 7 1998-01-26

English

Subject field(s)
  • Tectonics
CONT

Let us consider ... a relatively resistant bed ... included within a more plastic mass ... and in the act of bending ... The pressure that is exerted upon the separation surface evidently being the same in the two media, and the differences of principal pressures being equal to the respective thresholds, since there is deformation, the pressure that is exerted upon an element of surface normal to the limit is much less on the side where there is elongation (the extrados) in the resistant medium than in the plastic mass, and it may even be replaced by a tension which may be expressed by cracks.

French

Domaine(s)
  • Tectonique
DEF

Surface extérieure d'un pli correspondant à la partie ayant le plus grand rayon de courbure.

CONT

Considérons [...] un banc relativement résistant [...], compris dans une masse plus plastique [...], et en train de se courber [...]. La pression qui s'exerce sur la surface de séparation étant évidemment la même dans les deux milieux, et les différences de pressions principales étant égales aux seuils respectifs puisqu'il y a déformation, la pression qui s'exerce sur un élément de surface normal à la limite est, du côté où il y a allongement (c'est-à-dire à l'extrados), beaucoup plus faible dans le milieu résistant que dans la masse plastique, et elle peut même être remplacée par une tension, qui peut se traduire par des craquelures.
