Unison Industries has announced design enhancements to its conformal ‘Integrated Fin Technology’ surface coolers which are in service on GE-powered 787 aircraft. They were also selected for the Leap-1B and the new GE Passport engine. Unison said the lower weight design, which produces less drag, would save customers thousands of dollars annually in specific fuel consumption. The company said an additional benefit to the new design is flexibility in cooler shape, since the heat exchangers are no longer limited to “box” configurations. Unison also announced a newly designed Engine Build-Up (EBU) for the LEAP–1A engine application on the A320neo. The new EBU contains 300 unique tubes, brackets, harnesses and sensors which connect all the major engine systems to the aircraft.
