Cutting-edge aircraft PTMS for advanced power generation and enhanced cooling capability. Utilizing shared turbomachinery to fulfil both power generation and cooling requirements, Honeywell’s Power and Thermal Management System (PTMS) optimizes efficiency, resulting in a notable reduction in overall aircraft size and weight, particularly evident in existing military configurations.Throughout extensive flight operations spanning hundreds of thousands of hours, the PTMS has consistently delivered reliable performance to its operators, facilitating main engine starting, effective cooling, ground maintenance, and timely provision of emergency power whenever necessary.This pioneering integration is showcased on the F-35 Joint Strike Fighter aircraft and is adaptable for more electric architecture (MEA) aircraft.Advantages over conventional PTMS solutions include:
Reduction in aircraft weight by approximately 1,000 pounds
Marked improvement in reliability
Lowering of aircraft life cycle costs
Shortening of aircraft length by around 10 inches
On the F-35 platform, the integrated power package provided by the PTMS caters to the electrical power demands for main engine startup, auxiliary functions, and emergency power requirements while effectively managing the aircraft’s thermal loads.
