A bstract : To demonstrate cooling and heat transfer technology, a core engine test was conducted with a turbine inlet temperature 1700°C. Measurement data were compared with predictions for a vane, a blade, and a disk. Measured cooling effectiveness of the blade and the vane agreed well with predictions. CFD analysis was carried out for verification of the heat transfer coefficient which was adopted from a heat conduction analysis over the disk. The CFD model including bolt heads showed better results than an axi‐symmetric model.
