Aiming at design process of aeroengine turbine rotor blade, its platform was developed. One-dimensional performance design module was developed with aerothermodynamics. Based on planar cascade method, the two-dimensional aerodynamic design module which can predict the performance of the cascade quickly was built. The cooling blade and multi-disciplinary design optimization module were built with multi-disciplinary method based on the cooling blade parametric design. The multi-disciplinary design optimization of a cooling blade was obtained by the design platform, which effectively improve the blade integrated performance and validate the platform efficiency.
