Title (EN) CLOSED STRUCTURAL ASSEMBLY WITH IMPROVED RESISTANCE TO COMPRESSION
(FR) ENSEMBLE STRUCTURAL FERMÉ À TENUE À LA COMPRESSION AMÉLIORÉE
Abstract:
(EN) The invention concerns a structural assembly (100) comprising: - a closed chain defining a closed peripheral contour lying within a plane, comprising a plurality of successive structural links (200), each structural link comprising two structural branches (201a, 201b) facing one another and of convexity oriented in substantially opposing directions, linked together at each of the opposing ends (204a, 204b) thereof by a so-called end node (300), - means (400, 500) for geometrically stabilising the peripheral contour, said means being disposed in such a way as to prevent the geometric deformation of the peripheral contour in the plane under the effect of external pressure forces exerted, and said means comprising: - for each link (200), a first inextensible stabilising member (400) linking two branches (201a, 201b) of a same link, excluding the end nodes (300), - a second inextensible stabilising member (500) linking two non-adjacent end nodes of two separate links. The structural assembly is advantageously intended for the production of stratospheric balloons.
(FR) L'invention est relative à un ensemble structural (100) comportant : - une chaîne fermée définissant un contour périphérique fermé s'inscrivant dans un plan, comportant une pluralité de maillons structuraux (200) successifs, chaque maillon structural comportant deux branches structurales (201a, 201b) en vis à vis, de convexité orientée dans des directions sensiblement opposées, liées entre elles en chacune de leurs extrémités opposées (204a, 204b) par un nœud dit d'extrémité (300), - des moyens (400, 500) de stabilisation géométrique du contour périphérique, lesdits moyens étant disposés de telle sorte à empêcher une déformation géométrique du contour périphérique dans le plan sous l'effet de forces de pression externes exercées, et lesdits moyens comportant : - pour chaque maillon (200), un premier élément (400) de stabilisation inextensible reliant deux branches (201a, 201b) d'un même maillon, hors nœuds d'extrémité (300), - un second élément (500) de stabilisation inextensible reliant deux nœuds d'extrémité non adjacents de deux maillons distincts. L'ensemble structural est avantageusement destiné à la réalisation de ballons stratosphériques.
