TUBITAK MAM
MMU LSS – Life support system
It gives the oxygen separated from the engine exhaust air to the pilot as breathing air and protects the pilot from anti-G loads.
MMU ExPS – Explosion prevention system
It reduces the risk of explosion caused by fuel vapor in the aircraft and prevents fuel boiling in the fuel tank.
MMU HAVSET – Low visibility set for air duct
It is a set that provides low visibility on radar by being placed in the air duct.
MMU FRESEC – Electromagnetic modeling and application of frequency selective surfaces with low visibility

MMU LSS - نظام دعم الحياة
يعطي الأكسجين المفصول من هواء عادم المحرك إلى الطيار كهواء يتنفس ويحمي الطيار من الأحمال المضادة لـ G.
MMU ExPS - نظام منع الانفجار
يقلل من مخاطر الانفجار الناجم عن بخار الوقود في الطائرة ويمنع غليان الوقود في خزان الوقود.
MMU HAVSET - مجموعة الرؤية المنخفضة لمجاري الهواء
إنها مجموعة توفر رؤية منخفضة على الرادار من خلال وضعها في مجرى الهواء.
MMU FRESEC - النمذجة الكهرومغناطيسية وتطبيق الأسطح الانتقائية للترددات ذات الرؤية المنخفضة
