【実用新案登録請求の範囲】[Scope of utility model registration request] 高速で回転するハブと、このハブから径方向に
突出して遠心力により空気を加速する翼とを備え
る圧縮機において、翼の先端部の迎え角が根元部
より小さくなるように、翼中心線を前縁先端部で
大きく湾曲させたことを特徴とする圧縮機。 In a compressor equipped with a hub that rotates at high speed and blades that protrude radially from the hub and accelerate air by centrifugal force, the blade centerline is set so that the angle of attack at the tip of the blade is smaller than at the root. A compressor characterized by a large curve at the tip of its leading edge.
