Title
(EN) LIGHTNING PROTECTION APPARATUS AND METHOD
(FR) APPAREIL ET PROCEDE DE PROTECTION CONTRE LA FOUDRE
Abstract
(EN) A deployable lightning protection apparatus particularly suited for use with an aircraft radome comprises; a source of electrically conducting fluid (5); a delivery means (3, 4, 7) for delivering the conducting fluid to the surface of the radome prior to a lightning strike; a control means (1, 2) for controlling the delivery means; and means for directing the conducting fluid across the outer surface of the radome thereby providing a conductive channel for the passage of electrical current resulting from a lightning strike and dissipating said current without damage to the radome. The apparatus allows lightning protection to be deployed in response to a change in atmospheric conditions indicative of a high probability of lightning strike and removed when the danger of lightning strike has passed.
(FR) La présente invention concerne un appareil de protection contre la foudre déployable qui convient particulièrement à l'utilisation avec un radôme d'aéronef et qui comprend : une source de fluide électroconducteur (5); un moyen de distribution (3, 4, 7) permettant de distribuer le fluide conducteur jusqu'à la surface du radôme avant le foudroiement ; un moyen de commande (1, 2) permettant de commander le moyen de distribution ; et un moyen permettant de diriger le fluide conducteur sur la surface extérieure du radôme, afin de constituer un canal conducteur pour le passage du courant électrique produit par le foudroiement et de dissiper ledit courant sans endommager le radôme. L'appareil de l'invention permet de déployer une protection contre la foudre en réponse à un changement dans les conditions atmosphériques indiquant une probabilité élevée de foudroiement, et d'enlever cette protection lorsque le danger de foudroiement a cessé.
