TURBINE BLADE COMPRISING A TWO-PHASE THERMAL CONTROL SYSTEM (HEAT PIPE)

Abstract

BLADES COMPRISING A TWO-PHASE THERMAL CONTROL SYSTEM (HEAT PIPE) One aspect of the invention relates to a turbomachine blade (2), in particular a stator blade, the blade comprising: a leading edge (20), a trailing edge (21), an intrados surface and an extrados surface extending from the leading edge (20) to the trailing edge (21), the assembly constituting the body (23) of the blade, a tip (24) and a foot (22), the blade (2) comprising a hollow part extending from the tip (24) to the body (23), the hollow part comprising a capillary heat pipe (1) comprising a reservoir (130) and a circuit (140) extending from the tip (24) to the body (23), and a fluid in a liquid-vapor equilibrium state filling said reservoir (130) in the total absence of any other gas in said reservoir, The fluid is configured to circulate in the heat pipe (1) when temperature gradients form on the reservoir (130).
