The blade profile dimensions were 50 mm in span, and 24, 36, 48 and 60 mm in chord length which were 2.08, 1.39, 1.04 and 0.83 in AR (aspect ratio). The results are as follows. [1] In the case of αi (attack angle) over about 5° e (turning angle) increases and in the case αi=0° it decreases gradually with increasing AR. These tendencies become clearer with increasing a (stagger angle). [2] Total pressure loss coefficient takes a minimum value at AR≒1 independently of α and αi. (The Reynolds number effect has not been investigated in this report). [3] (1) At aαi=constant, axial velocity ratio decreases gradually to a fixed value close to 1 with increasing AR in the case α=0°. (2) Axial velocity ratio keeps almost constant value independently of AR in the case α=30°. (3) ln the cases α=50° and 60°, axial velocity ratio keeps almost constant value when AR is less than about 1, but when AR is larger it increases at αi≥5~10° and decreases at αi=0° with increasing AR.}, pages = {135--145}, title = {Performances of Cascade of blades with small aspect ratio.
