US Patent 11873073 Fuel cooled multi-function aperture

Phased array antennas, such as a multi-function aperture, are limited in performance and reliability by traditional air-cooled thermal management systems. A fuel-cooled multi-function aperture passes engine fuel through heat exchangers that surround the multi-function aperture to provide better heat transfer than can be achieved through air cooling systems. The increased heat transfer and thermal management results in a multi-function aperture with improved performance and reliability.
