A high-temperature test facility is being installed in the Air Force aero propulsion laboratory for analyzing various sophisticated cooling designs over an extended gas temperature range. The objective is to evaluate these schemes with respect to gas temperature and pressure levels. The experimental data will be correlated with theoretical predictions to provide a basis for future high-temperature turbine blade designs. The report describes a theoretical prediction of the convection heat-transfer coefficient distribution on a test blade and the computer program for making the necessary calculations. The program is written in Fortran 4 ready for an IBM 7094. The input and output are described. The program starts with the blade surface pressure distribution obtained experimentally and yields the heat-transfer coefficients on the blade contour.
