Filed: 1993-02-01
Abstract: PURPOSE:To reduce a generation amount of separated turbulence so as to reduce noise by setting the maximum projection point on a negative pressure surface side so as to be positioned in a specific range in rear of the center of a chord. CONSTITUTION:In a negative pressure surface 25 in a blade cross section cut from the center of a fan boss along a optional radius, the front end 24a and the rear end 24b of the blade cross section are connected to each other. The maximum projection point 28 of a part which is most separate from a chord 27 connected in such way is set so as to be positioned in a specific range in rear of the center 27a of the chord 27. In this case, when the length of the chord 27 in the blade cross section is set to C, and a length along the chord 27 from the front end 24a in the blade cross section up to the maximum projection point 28 is set to L, the value of L/C is set to be in the range of 0.55 to 0.85. Therefore, at the time of rotation of a blade 24, a released point 29 generated on the negative pressure surface 25 side is positioned in the side more rear than that of a prior art so as to reduce a generation amount of separated turbulence.
