Novel cooling design for blade or vane trailing edges
, 2019 The trailing edge of the high pressure turbine blade and vane presents significant challenges to the turbine cooling engineer. This section endures very high temperature and mechanical stresses but aerodynamic efficiency requirements dictate that it must be tapered to the end with minimal thickness, making it difficult to cool internally. Pressure side
