PTMS
Our PTMS is the backbone of the aircraft — delivering essential power and thermal performance in one integrated, combat‑proven system. Built to fight today and evolve with the F‑35 mission, without redesign risk.
The power and thermal management system (PTMS) is responsible for optimizing energy usage and ensuring proper cooling of the aircraft's advanced avionic systems.
Our cabin and equipment air cooling and pressurization system maintains an ideal environment for both the pilot and onboard systems. This is critical for the pilot’s comfort and safety as well as the efficient functioning of equipment.
The GTS130 auxiliary power unit (APU) provides auxiliary and emergency power, assists in engine start-up and maintains power for onboard systems when the engines are off.
The liquid cooling subsystem plays a crucial role in maintaining the optimal temperature for the electronic systems. By preventing overheating, it ensures efficient functioning and longevity of critical systems.
Honeywell’s bleed air control subsystem manages the engine's operating temperatures, which is vital for performance and longevity.
The fuel thermal management system regulates fuel temperature to optimize combustion and engine performance, while enhancing overall fuel efficiency.
Our fan duct heat exchangers and precooler systems maintain the thermal balance necessary for the durability and reliability of the aircraft’s systems.
Honeywell’s OBOGS uses ambient air to produce breathable oxygen for the pilot. This saves weight and space on the aircraft, enhancing operational efficiency.
