Multiple precision MDO strategy for turbine blade

  • Based on kinds of different precise analysis methods on the turbine design,the multiple precision strategy was put forward in order to balance the cost and the precision on turbine MDO.This strategy studied the variable complexity method (VCM) which was improved by the two-point scale function, the new updating technology and three kinds of precise models including the fluid-solid closely couple analysis,the fluid-solid-thermal loosely couple analysis and the approximate equation.The strategy solves the difficulty of disciplinary decoupling and coordination by the collaborative optimization (CO) strategy.Finally,using 9 high precision fluid-solid coupling analysis,the new strategy can finish the turbine MDO with acceptable performance.
