Abstract
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 channels within the ribs of the multi-function aperture to provide better heat transfer than can be achieved through air cooled systems. The increased heat transfer and thermal management results in a multi-function aperture with improved performance and reliability.
Claims16
A fuel-cooled multi-function aperture comprising:
- a multi-function aperture comprising a plurality of circuit card modules, wherein each of the plurality of circuit card modules comprises:
- a first circuit card;
- a second circuit card;
- and
- a rib positioned between the first circuit card and the second circuit card, wherein each rib includes:
- a first channel extending from a first edge of the rib into a center portion of the rib and exiting through a third edge of the rib, wherein the first channel is configured to receive cool fuel through the first edge of the rib and dispense heated fuel through the third edge of the rib;
- and
- a second channel extending from a second edge of the rib into the center portion of the rib and exiting through the third edge of the rib, wherein the second channel is configured to receive cool fuel through the second edge of the rib and dispense heated fuel through the third edge of the rib;
- and
- a first manifold including a first inlet and a second manifold including a second inlet,
- wherein the first inlet and the second inlet are configured to receive fuel and are in fluid communication with the first channel and the second channel of the rib.
