Abstract

L’invention concerne un tapis chauffant (1) pour le chauffage d’une pièce en particulier d’une turbomachine d’aéronef, ce tapis (1) étant déformable et comportant une face (1a) configurée pour épouser la pièce et être appliquée contre cette pièce, caractérisé en ce qu’il comprend une structure multicouche comportant plusieurs couches polymériques superposées dans lesquelles sont noyés : une pluralité de sondes de température (11),une pluralité d’éléments résistifs de chauffage (13), une pluralité d’unités de contrôle (15) reliées aux sondes (11) et aux éléments (13), etdes quadrillages de fils conducteurs configurés pour relier les sondes (11), les éléments (13) et les unités (15) entre eux ainsi qu’à un module (5) d’alimentation électrique (5a) et de commande (5b) du tapis chauffant (1). L’invention concerne aussi un procédé de chauffage d’une pièce (3) de turbomachine d’aéronef, comprenant l’application d’un tapis chauffant (1). Figure pour l'abrégé : Figure 2The invention relates to a heating mat (1) for heating a part in particular of an aircraft turbomachine, this mat (1) being deformable and comprising a face (1a) configured to fit the part and be applied against this part, characterized in that it comprises a multilayer structure comprising several superimposed polymer layers in which are embedded: a plurality of temperature probes (11), a plurality of resistive heating elements (13), a plurality of units control (15) connected to the probes (11) and the elements (13), and grids of conductive wires configured to connect the probes (11), the elements (13) and the units (15) to each other as well as to a module (5) for power supply (5a) and control (5b) of the heating mat (1). The invention also relates to a method of heating a part (3) of an aircraft turbomachine, comprising the application of a heating mat (1). Figure for abstract: Figure 2
