CERAMIC CORE TAPERED TRIP TRIPS, CORE DIE AND TURBINE BLADE

摘要

A core (15) for creating an airfoil has a ceramic material that forms a body. The body has an outer dimension, a slot (25) extending through the outer dimension and into the body for receiving an insert (20), the slot (25) disposed at an angle to the outer dimension, and a trip strip (65) having a first portion (70) disposed in the outer dimension. The first portion (70) is in register with the slot (25) wherein a constant dimension such as minimum thickness (D) is maintained between the trip strip (65) and the slot (25) along a length of the slot (25) and wherein said first portion (70) tapers towards said outer dimension.
