Abstract

يتعلق الاختراع الحالي بطريقة إصلاح repair method (72) لتمديد عمر خدمة قرص تربين قدرة power turbine disk (12) تعرض لضرر التآكل، حيث يتضمن تربين القدرة power turbine (14) مراحل stages (16، 18، 20، 22) وفجوات بين المراحل interstage gaps (26، 28، 30، 32). وتتضمن الطريقة (72) إجراء تحليل حراري thermal analysis أول (74) لتكوين أساسي من قرص أساسي غير معرض للتآكل لتحديد توزيع درجة حرارة ثابتة أول (44). ويجرى التشغيل الآلي then machined (76) بعد ذلك لقرص معرض لضرر التآكل corrosion damaged disk (12) إلى عمق مناسب لإصلاح التآكل من أجل تشكيل قرص مدار بالآلات . ويجرى تحليل حراري thermal analysis ثان (78) للقرص المدار بالآلات لتحديد توزيع درجة حرارة ثابتة ثان للقرص المدار بالآلات. ويجرى بعدها حساب عمر دوري آمن متوقع predicted safe cyclic life (PSCL) أول (80) لسمات القرص المتماثلة مع المحور (1-10) الخاصة بالقرص المدار بالآلات. ويُحسب أيضًا PSCL ثان (82) لسمات قطعة على شكل شجرة تنوب للقرص (70) الخاصة بالقرص المدار بالآلات machined disk. وبصورة إضافية، يتم تأهيل (84) الطريقة (72) لضمان أن جودة القرص
