| Abstract: | Tip clearance of turbine blade has effect on the performance of aeroengine, conversion of dimensions from high temperature to low temperature for turbine components is an important content of tip clearance design. In this paper, design optimization is introduced to solve the problem of converting dimension. Using this method, a blade is analyzed; the result is reasonable with comparison to simple method,and design optimization is feasible. Finally, it successfully completes the dimension conversion of turbine components at hot and cold conditions. |
