Component with mechanical locking features incorporating adaptive cooling and method of making

A hot gas path component assembly comprising:

• a first component portion comprising a first set of interlocking features;
• a second component portion comprising a second set of interlocking features, the second set of interlocking features mechanically coupled to the first set of interlocking features;
• and
• fill material disposed at an interface between at least one surface of the first set of interlocking features and at least one surface of the second set of interlocking features;
• wherein the fill material is disposed during a joining process;
• and
• wherein the second component portion is joined to the first component portion via both the fill material and the first and second sets of interlocking features;
• and
• further comprising an adaptive cooling passage,
• wherein a first end of the adaptive cooling passage is fluidly connected to a cooling source;
• wherein a second end of the adaptive cooling passage is disposed within the fill material between the first component potion and the second component portion;
• and
• wherein cooling fluid flows into the interface between the first component portion and the second component portion only if there is a discontinuity in the fill material at the interface.

A structure comprising:

• a first structure portion comprising a first set of interlocking features;
• a second structure portion joined to the first structure portion, the second structure portion comprising a second set of interlocking features, the second set of interlocking features mechanically coupled to the first set of interlocking features;
• the first structure portion and the second structure portion collectively forming a first substrate surface, the first substrate surface exposed to hot fluid;
• fill material at an interface between the first structure portion and the second structure portion;
• and
• at least one adaptive cooling passage, the at least one adaptive cooling passage comprising:
• a first end fluidly connected to a cooling source;
• and
• a second end disposed at the interface between the first structure portion and the second structure portion;
• wherein cooling fluid flows into the interface between the first structure portion and the second structure portion only if there is a discontinuity in the fill material, and wherein the first structure portion is an airfoil body portion;
• and wherein the second structure portion is an airfoil tip portion or an airfoil trailing edge portion.
