The invention relates to a device (50) for de-icing the air intake (249 of a gas turbine (10), such as a helicopter turboshaft. The invention is characterised in that the device includes an essentially metal housing (52) for the air intake (24) in the gas turbine, said housing including a first opening (54) for the air inlet into the housing (24), said first opening (54) being provided with a first essentially metal grid (56), the housing further including a second opening (58) for directing the air towards the compression stage (20) of the gas turbine, and the device further including means (62, 64) for generating in the housing electromagnetic waves at a frequency adapted for melting down rime.
L'invention concerne un dispositif de dégivrage (50) d'une entrée d'air (24) d'une turbine à gaz (10), tel un turbomoteur d'hélicoptère. L'invention se caractérise par le fait que ledit dispositif comporte une enceinte (52) essentiellement métallique pour l'entrée d'air (24) dans la turbine à gaz, ladite enceinte comportant une première ouverture (54) pour l'entrée d'air dans l'enceinte (24), ladite première ouverture (54) étant munie d'une première grille essentiellement métallique (56), l'enceinte comportant en outre une seconde ouverture (58) destinée à diriger l'air vers un étage de compression (20) de la turbine à gaz, ledit dispositif comportant en outre des moyens (62, 64) pour générer dans l'enceinte des ondes électromagnétiques ayant une fréquence permettant de faire fondre du givre.
