Abstract

The invention relates to an impeller in a turbomachine and a heat pipe temperature management system for the impeller. The turbomachine includes a compressor configured to compress air received at an intake portion to form a compressed airflow that exits into an outlet portion. A combustor is operably connected with the compressor, and receives the compressed airflow. A turbine is operably connected with the combustor, and receives combustion gas flow from the combustor. The turbine has a plurality of wheels and a plurality of buckets, and the turbine receives compressor bleed off air to cool at least one of the wheels. A cooling system is operatively connected to the turbine, and includes a plurality of heat pipes attached to or embedded within at least one of the wheels. The compressor bleed off air is configured to impinge onto at least one of the wheels or the heat pipes. The heat pipes and the compressor bleed off air are configured to cool the wheels.
