Abstract

Shutter device for parachute-wing. The invention relates to a shutter device making it possible to control the air flows within a wing of flexible or semi-rigid structure and its deflation. It consists of surfaces made of fabric or flexible materials performing the role of shutters and being able to mask the apertures in front of which they are fixed. The device according to the invention relates to the wings of the parachute-wing and parapent type.

Description

CLAPET POUR PARACHUTE-AILE
La présente invention concerne un système de régulation des flux d'air et des dégonflements à l'intérieur d'une structure souple ou semi-rigide d'une aile de type parachute-aile, à l'aide de surfaces en tissu ou matériaux souples jouant le rôle de clapet.WING PARACHUTE VALVE
The present invention relates to a system for regulating air flows and deflations inside a flexible or semi-rigid structure of a wing of the parachute-wing type, using fabric or flexible material surfaces. playing the role of valve.

Habituellement sur les parachutes-ailes, des ouvertures sont pratiquées dans les tissus de maintien du profil afin de régulariser la pression interne, et à l'avant pour l'admission de l'air à l'intérieur de la structure. Usually on the wing parachutes, openings are made in the tissues for maintaining the profile in order to regulate the internal pressure, and in the front for the admission of air inside the structure.

Mais ces mêmes ouvertures peuvent accélérer le dégonflement de l'aile, une perte de pression pouvant se communiquer d'alvéole en alvéole. However, these same openings can accelerate deflation of the wing, a loss of pressure that can be communicated from cell to cell.

Le présent dispositif pallie à ces inconvénients. The present device overcomes these drawbacks.

I1 se compose d'une surface en tissu ou en matériaux souples faisant office de clapet anti-retour. Ce clapet est fixé sur la surface ou se situe l'ouverture et peut la masquer partiellement ou totalement. It consists of a surface made of fabric or flexible materials acting as a non-return valve. This valve is fixed on the surface where the opening is located and can partially or totally mask it.

L'air peut être admis dans un sens, la pression repoussant le clapet, mais non dans l'autre, la pression refermant le clapet sur l'orifice. Air can be admitted in one direction, the pressure pushing the valve, but not in the other, the pressure closing the valve on the orifice.

Ainsi le sens des flux d'air dans la structure peut être contrôlé. Thus the direction of the air flows in the structure can be controlled.

Cette invention concerne les ouvertures pratiquées sur toutes les ailes souples ou semi-rigides de type parachutesailes, parachute de pente ; notamment les portions d'aile au dégonflement rapide, les alvéoles ou caissons fermés, les ouvertures du bord d'attaque de l'aile.  This invention relates to the openings made on all the flexible or semi-rigid wings of the parachutesail type, slope parachute; in particular the wing portions with rapid deflation, the closed cells or boxes, the openings of the leading edge of the wing.
