    Understanding Repair Limits for Air Seal Serration in Gas Turbine High Pressure Rotor Sections

    Sidebar: I am trying my best to illustrate how I am conceptualizing the serration flow path in my head. PLEASE, feel free to point out any and all flaws in my analogies/comparisons so that I might gain a better understanding of the intent / theory behind serration flow pathing. - HPProfessor

    Understanding Repair Limits for Air Seal Serration in Gas Turbine High Pressure Rotor Sections

    Hey Dave and SW, Perhaps my lack of experience has lead me to ask a question that general theory is not applicable to. I apologize if that’s the case. I did not major in fluid mechanics so my background knowledge has some holes in it (no pun intended). Let me try to simplify the question...

    Understanding Repair Limits for Air Seal Serration in Gas Turbine High Pressure Rotor Sections

    Hello Wil! Thank you so much for the response. I hope I didn’t cause any uneasiness about proprietary information. This example of two components in the High Pressure Turbine Section is seen across many different Gas Turbine Engine Models and OEMs. The very vague description I gave can be...

    Understanding Repair Limits for Air Seal Serration in Gas Turbine High Pressure Rotor Sections

    Hello, I am looking for some general insight on the function of “knife” edge Air Seal Serrations in Gas Turbines. I have recently stumbled upon two components in the same High Pressure Rotor Section of a Gas Turbine engine, both of which are capable of maintaining engine service parameters...
