The second book of the set of works by the CIDECT [Committee International for the Development and the Study of Tubular construction] under the general title "Construction with Hollow Steel Sections" is dedicated to phenomena of instability : buckling, distortion, spreading. Because of the shape of its section and the particularly favourable distribution of matter in the straight section, a hollow profile, of circular or rectangular shape, behaves distinctly better than an open profile section under the demands of compression. In remaining within the limits of the relation of the diameter or the width of side divided by the thickness of partition, given in this dimensioning guide, the local hollow profile distortion can be disregarded. On the other hand, the resistance to spreading is, in practice, not verified because hollow profiles possess a distinctly larger polar rigidity than open section profiles.

CONT

Le second livre de la série mise en œuvre par la CIDECT [Comité International pour le Développement et l'Étude de la Construction Tubulaire] sous l'intitulé «Construire avec des profils creux en acier» est consacré aux phénomènes d'instabilité : flambement, voilement, déversement. À cause de la forme de sa section et de la distribution particulièrement favorable de la matière dans la section droite, un profil creux, de forme circulaire ou rectangulaire, se comporte nettement mieux qu'un profil ouvert sous des sollicitations de compressions. En restant dans les limites du rapport du diamètre ou de la largeur de côté divisé par l'épaisseur de paroi, données dans ce guide de dimensionnement, le voilement local des profils creux peut être négligé. D'autre part, la résistance en déversement n'est, en pratique, pas à vérifier car les profils creux possèdent une rigidité polaire nettement plus grande que celle des profils à section ouverte.

DEF

Structural shape. General term applied to rolled flanged shapes, having at least one dimension of their cross-section 76 mm (3 inches) or greater, which are used in the construction of bridges, buildings, ships, railroad rolling stock and for numerous other constructional purposes.

DEF

Profile. A product of uniform cross-section along its whole length, with a cross-section other than rod, bar, wire, tube, sheet or strip, supplied in straight lengths or in coiled form. According to the form of its cross-section, it is called :-hollow profile : the cross-section other than tube enclosing one or more complete voids;-solid profile : the cross-section does not enclose any complete void. The cross-sections are formed by extruding, rolling, roll-forming, or drawing, either exclusively or in combination.

OBS

In the past the terms, "shapes" and "sections" were used synonymously. The American Institute of Steel Construction and the producers have now adopted "shapes" as the standard designation.

DEF

Barre d'acier ou d'un autre métal, dont la section a une forme déterminée : les rails sont une variété de profilés; les tôles et les profilés.

DEF

Produit de section transversale constante sur toute sa longueur, de section différente de celles des barres, fils, tubes, tôles ou bandes, livré en longueurs droites ou enroulé. Conformément à la forme de sa section transversale, il est appelé : - profilé creux : section transversale autre que tube avec ou plusieurs creux fermes; - profilé plein : la section transversale ne comprend aucun creux fermés. Les sections transversales sont obtenues par filage, laminage, profilage ou étirage soit exclusivement par l'un de ces procédés, soit par une combinaison de ceux-ci.

OBS

L'élegance des profils extrudés donne un avantage considérable aux éléments linéaires d'aluminium.

OBS

Profil. Sous l'influence de l'anglais, quelquefois confondu avec le terme «profilé».

The X-wing has emerged from the circulation controlled rotor(CCR) in which a hollow blade of roughly oval aerofoil section, that is, without a real lifting profile at all, can be made to lift effectively by blowing a layer of air through a slot and across the curved Coanda surface which forms the trailing-edge. While this in itself produces lift, the air jet can be so modulated as the rotor turns that it has the same effect as the cyclic pitch changing of the normal rotor. Finally, a further jet can be blown through a second slot near the leading-edge of the blade so that it restores the lost lift of the retreating blade. This fore-and-aft blowing is the key to the stopped-rotor X-wing.
