Definitions
- Fig. 2 is a partial view of a revolution locus of blade 2 of impeller 1.
- the revolution locus drawn by leading edge 6 of blade 2 shows a valley in an upper half thereof and a peak in a lower half, with regard to windward.
- the upper half of the blade 2 is defined as a portion between around the blade center and the outer end 8 (hereinafter referred to as "tip 8"), while the lower half of the blade 2 is defined as a portion between around the blade center and the hub 3.
- Line B-B is drawn by connecting respective midpoints of leading edge 6 and trailing edge 7 of blade 2.
- Line B-B shows a center of passage through which the airflow flows in the direction indicated by the arrow mark.
- Line C-C shows a hub center i.e. a rotation center of impeller 1.
