High-temperature alloy blade capable of guaranteeing efficient cooling of front edge of blade for engine

The invention provides a high-temperature alloy blade capable of guaranteeing efficient cooling of the front edge of a blade for an engine, relates to the technical field of blade cooling, and aims at solving the problems that most existing blade cooling modes are active cooling modes, cold air is input by separating out part of power of the engine, the load of the engine is increased, the service life is shortened, the cooling efficiency of an air film on a blade is greatly influenced by the air blowing ratio and is also partially influenced by the Reynolds coefficient, and the contact time of cold air and the tail end of the blade is short. The blade comprises a blade body; a blade tenon root part is fixedly mounted at the root part of the blade body; arc-shaped skirts are fixedly mounted on the left side and the right side of the joint of the blade tenon root part and the blade body respectively; and the blade body is inserted between the skirts. Due to the fact that outwards-protruding blade tail edge gui
