High-pressure ratio compressor blade connecting outer ring for ship gas turbine

The invention belongs to the technical field of gas turbine equipment, and particularly relates to a high-pressure ratio compressor blade connecting outer ring for a ship gas turbine. The blade connecting outer ring comprises a blade, stop pins and an outer ring body. The outer ring body is connected with the blade through the stop pins. Wear-resistant coatings are arranged on the inner surface ofthe outer ring body and refer to polybenzoate aluminum-silicon coatings. A tenon is arranged at the outer diameter position of the blade. The front side and the rear side of the axial position of theblade are each provided with a protruded boss. The bosses form a circular boss with the inner and outer diameter dimensions through the whole circle of the blade. Six stop holes are circumferentiallydistributed in the whole circle of the boss. The outer ring body is a ring piece, and the front side and the rear side of the outer ring body in the axial direction are each provided with a groove used for being matched with t
