HoneyWell a fourni l'unité ptms sur chaque F-35.

Ce dispositif a été critiqué par son inaptitude à refroidir la cellule du F-35 correctement, ce qui met le réacteur à contribution et diminue sa durée de vie.
La firme HoneyWell propose maintenant un upgrade software et puis hardware permettant d'augmenter les performances de l'unité ptms.
Le JPO est interessé par cette solution.
La question suivante a été posée au responsable de la firme
The F-35 JPO is considering upgrading the PTMS on the worldwide F-35 fleet. Tell us about this system and the benefits of upgrading the existing Honeywell-built PTMS instead of replacing it with a completely new system.
selon lui, attention c'est un publireportage
,voici les nouveaux avantages de la solution en deux étapes proposée par sa firme.
With a software upgrade, we can boost cooling capacity 25% to 40kW by 2029, reducing bleed air usage by up to 41% and thereby extending F135 engine life.
Then there’s a longer-term upgrade path that enables us to get significantly higher than that. Honeywell demonstrated the ability to upgrade PTMS’ cooling capacity to 80kW while reusing 95% of PTMS hardware and 80% of PTMS software, significantly reducing development and retrofit costs, risks, and mission readiness impacts. Upgrades to reach 80kW are already at TRL 7+, ready for Block 4 and beyond.
