When the operating conditions of turbomachinery are changed, as when a gas turbine is accelerated, heat is transferred from or to the various components of the machine. One of the significant heat transfers is with the blading. Several simple models for the blade and platform arrangement are compared. Satisfactory representation is obtained from a simple eight-element Finite Difference Model and from a Revised Fin Model. Computer running times are similar, but the latter allows more convenient
