Power and Thermal Management System

Power & Thermal Management System (PTMS) | Honeywell Aerospace

By integrating three aircraft systems into one, the Honeywell power and thermal management system (PTMS) increases efficiency and reliability and reduces system life-cycle costs for the operator.

Our power and thermal management system (PTMS) integrates a conventional auxiliary power unit, environmental control system and emergency power into a single system. This integrated package, outfitted on the F-35 Joint Strike Fighter aircraft and available for more electric architecture (MEA) aircraft, represents a first for the industry.

Our advanced technology offers a dramatic contrast against conventional systems, including:

  • Savings in aircraft weight of about 1,000 pounds
  • Savings in aircraft length of about 10 inches
  • Significantly increased reliability
  • Savings in aircraft life cycle cost

On the F-35, the PTMS integrated power package delivers electrical power for the aircraft main engine start, auxiliary, and emergency power needs, while simultaneously providing thermal management of the aircraft heat loads.
