Regenerative turbine blade and vane cooling for a tip turbine engine

A tip turbine engine comprising:

• a compressor for compressing a core airflow;
• a fan for accelerating bypass airflow and having a core airflow passage that receives said core airflow from said compressor;
• an annular combustor for introducing fuel and combusting said core airflow from said fan;
• and
• a turbine for extracting energy from said core airflow exiting said annular combustor, said turbine having at least one stage defined by a turbine blade that extends from a fan blade and a turbine vane, wherein said vane has a vane passage to receive a regenerative cooling airflow portion of said core airflow from said fan, said regenerative cooling portion of said core airflow exiting said vane passage for communication to said annular combustor, said regenerative cooling airflow portion of said core airflow is communicated through a turbine blade passage of said turbine blade prior to communication through said turbine vane passage.
