Heating apparatus specifically adapted for the heat treatment of turbine blades comprises two parts (10,11) which may be pivotally connected by a hinge (17), the support parts (10,11) carrying heating elements (14,15) and a slot (20) the provision of the slot (20) enabling the heating apparatus to be slid over the trailing edge of the turbine blade into position on the blade and subsequently closed by closure member (24) this enables the rapid application of heating apparatus for heat treatment processes which has hitherto been a complicated andtime consuming operation. The heating apparatus may incorporate thermocouples (27) and heat sinks.
ppareil de chauffage spécialement adapté pour le traitement thermique d'aubes de turbines composé de deux pièces (10, 11) pouvant être solidarisées par une charnière permettant une rotation (17), les pièces de support (10, 11) portant les éléments chauffants (14, 15) et une fente (20), ladite fente permettant de glisser l'appareil de chauffage sur le bord de fuite de l'aube de turbine de façon à le positionner sur l'aube puis à le fixer au moyen d'un élément de fermeture (24), ce qui permet d'accélérer la mise en oeuvre de l'appareil de chauffage aux fins des traitements thermiques, lesquels représentaient jusqu'à maintenant une opération longue et complexe. L'appareil de chauffage peut comprendre des thermocouples et des dissipateurs de chaleur.
