Based on the design philosophy of assembly between metal and non-metal materials, a turbine blade cooling scheme which applied arrayed ceramic matrix composite (CMC) armors was designed. These armors replaced the airfoil, and covered the high thermal load regions at the front part of the blade. And a few coolants were injected through the gaps between them, thus a well thermal protection to the metal substrate was achieved. A three-dimensional flow and thermal coupled numerical simulation method was employed, along with the comparison with a typical film cooling. The cooling enhanced mechanisms and attainable effects of this scheme were revealed, and some design criteria and methods were summarized. The novel scheme reduced the coolant mass flow rate by 24.2%, while improving the metal region cooling efficiency by 69.2%, up to a number of 0.95. Meanwhile, the temperature margin of the CMC armors was still above 130 K, which indicated the potential for further increasing the gas temperature beyond
