Abstract

PURPOSE: To increase the radiation area contacting eddy current for raising the radiation efficiency of a fan by connecting ribs to an adjacent blade and a disc.
CONSTITUTION: Three ribs are connected with an adjacent blade 4 and a disc 3 with the tip thereof 7 located on the disc 3 side of straight line 10 interconnecting the tip 8 of the disc 3 and the outer-circumference 9 of the end on which the blade 4 is located. The ribs 5 increase the radiation area contacting with the eddy current f2 generated in the vicinity 13 of the connection of the boss 2 and disc 3 with each other and the eddy currents f3 and f4 generated between the ribs 5 by a fan in operation so that the radiation efficiency of the fan 1 is raised.
