Abstract

يتعلق الاختراع الحالي بتجمعية مانعة للتسرب seal assembly بين تجويف قرصي disc cavity الشكل وممر غاز ساخن hot gas path بقسم تربين turbine section تتضمن تجمعية أرياش ثابتة stationary vane assembly وتجمعية أنصال دوارة rotat¬ing blade assembly بأسفل تجمعية الأرياش vane assembly وتتضمن مجموعة من الأنصال blades التي تكون مُرتكزة على منصة وتدور مع دوار التربين turbine rotor والمنصة platform أثناء تشغيل المحرك. تتضمن المنصة سطح أول موجه إلى الخارج بشكل قطري, سطح ثاني متجه قطرياً إلى الداخل, سطح ثالث, ومجموعة من الفجوات grooves التي تمتد إلى داخل السطح الثالث. يتم ترتيب الفجوات بحيث يتم تحديد المسافة بين الفجوات المجاورة. أثناء تشغيل المحرك, توجه الفجوات هواء التطهير purge air إلى خارج التجويف القرصي باتجاه ممر الغاز الساخن بحيث يتدفق هواء التطهير بالاتجاه المرغوب فيه بالنسبة للاتجاه حيث يتدفق الغاز الساخن عبر ممر الغاز الساخن.
