Claims19
A gas turbine engine, comprising:
- a compressor;
- a diffuser in fluid communication with the compressor;
- a combustor in fluid communication with the diffuser;
- a turbine in fluid communication with the combustor;
- a bearing system including a bearing configured to support the compressor and the turbine, an electro-thermal cooling system configured for removing heat from the bearing, a sump housing;
- and
- an aerogel insulation disposed around the sump housing configured to shield the sump housing from an external heat source.

A gas turbine engine, comprising:
- a compressor;
- a diffuser in fluid communication with the compressor;
- a combustor in fluid communication with the diffuser;
- a turbine in fluid communication with the combustor;
- a bearing system having a bearing, wherein the bearing is configured to support the compressor and/or turbine, wherein the bearing system includes an electro-thermal cooling system configured for removing heat from the bearing and a sump housing having fins;
