TRANSPIRATION BLADE
Document Type and Number:
Japanese Patent JP3319117
Kind Code:
B2
Abstract:
PURPOSE: To improve cooling performance and withstand use for a long time by tightly integrating a porous member part to a solid part.
CONSTITUTION: A transpiration blade has a tail shaped porous member part 2 for carrying out transpiration cooling, and solid parts 3, 4 which are enclosed the outer circumference of the porous member part 2 in a checker shape and being maintained strength, and the porous member part 2 and the solid parts 3, 4 are integrated tightly.
