摘要：A turbine design method that can easily construct a turbine stage structure inwhich an unsteady force acting on a rotor blade can be reduced and degradation inperformance and increase in rotor shaft length can be prevented is provided. Unsteadyforces and exciting forces by the potential field interaction acting on the rotor blade arerespectively obtained, exciting forces by the wake interaction acting on the rotor bladeare obtained, the exciting forces by the potential field interaction and the wakeinteraction are mathematically expressed, the unsteady force acting on the rotor bladewhen the distance between stator and rotor blades is an arbitrary value is calculated, andthe distance between stator and rotor blades is determined based on a calculationresult.
