Collins Aerospace, an RTX company, has conducted a successful lab test of its Enhanced Power and Cooling System (EPACS) that will provide over two times the current cooling capacity to facilitate the modernization of F-35.
The company anticipates EPACS will achieve Technology Readiness Level 6 in 2023 and be ready to begin an Engineering & Manufacturing Development program as early as 2024.
Through its more efficient thermodynamic cycle, EPACS provides significantly more cooling capacity to the platform and requires less energy from the engine, thus helping to unlock improved engine performance and durability. The system will deliver more than twice the current cooling capability to support additional growth beyond Block 4 and is expected to provide enough cooling capacity for the life of the aircraft. In addition, EPACS fits within the existing envelope and is intended to be compatible with all three F-35 variants.
Engineered to supply cooling, main engine start and emergency power functionality for the F-35, EPACS includes an air cycle system, electric power generator and controller from Collins along with an auxiliary power unit from Pratt & Whitney.
