US 12,448,901 B1 · Thermal management system for gas turbine engine with open propulsor

Abstract

A swirl recovery vane (SRV) includes a trunnion configured to pivotally connect to an exterior surface of an inner platform of an SRV structure system. The SRV includes a body extending radially from the trunnion to an unshrouded distal vane tip of the vane. The SRV includes a heat exchanger that includes a gas inlet configured to couple a bleed air valve of a compressor section of a gas generator to a gas channel. The heat exchanger includes the gas channel adapted to: enable gas to flow into the gas inlet as cool gas and out through a gas outlet as warm gas; and extend into the body of the vane to enable heat transfer from a heat source within the vane to the cool gas. The heat exchanger includes the gas outlet configured to output the warm gas from the channel to an ambient environment outside of the vane.

A swirl recovery vane (SRV) comprising:

a trunnion configured to connect to an exterior surface of an inner platform of an SRV structure system;
a body that extends radially from the trunnion to an unshrouded distal SRV tip of the SRV;
a heat exchanger located within the SRV, the heat exchanger comprising:
a gas inlet configured to couple a bleed air valve of a stage of a high or low compressor section of a gas generator to a gas channel;
the gas channel adapted to:
enable gas to flow in through the gas inlet as cool gas and out through a gas outlet as warm gas;
and
extend into the body of the SRV to enable heat transfer from a heat source within the SRV to the cool gas;
and
the gas outlet that outputs the warm gas from the gas channel to an ambient environment outside of the SRV.
