The blade tip crack of the high pressure turbine is repaired by using the laser welding, which can reduce effectively the repair cost and increase the economic effectiveness of the engine repair.
The calculation method for radial clearance of turbine blade tip considering the effect of temperature and rotational speed is developed in this paper.
