Abstract A heatshield for a gas turbine engine. The heatshield comprising a main body having a leading edge, a trailing edge, lateral edges, a first surface and a second surface, the first surface being exposed to a hot working gas in use passing through the gas turbine engine. The main body having an array of cooling channels for conveying a coolant flow, where each cooling channel of the array of cooling channels having and a surface. At least one cooling channel of the array of cooling channels comprising at least one flow disturbing feature extending from the surface and into the cooling channel. La présente invention concerne un bouclier thermique destiné à un moteur à turbine à gaz. Le bouclier thermique comprend un corps principal ayant un bord d'attaque, un bord de fuite, des bords latéraux, une première surface et une seconde surface, la première surface étant exposée à un gaz de travail chaud lors de l'utilisation passant à travers le moteur à turbine à gaz. Le corps principal comporte un réseau de canaux de refroidissement permettant de transporter un flux de fluide de refroidissement, chaque canal de refroidissement du réseau de canaux de refroidissement ayant une surface. Au moins un canal de refroidissement du réseau de canaux de refroidissement comprend au moins un élément de perturbation de l'écoulement s'étendant de la surface et dans le canal de refroidissement.
