In a previous paper, it was reported that the unsteady forces and moments obtained by the proposed "experimental method of the small-scale vibrating cascade" having the same splitter blade profile as main blade were in good agreement with those obtained by the conventional method of vibrating all blades. The splitter blade profile is generally different from the main one in the circular cascade, so that it is necessary to verify the usefulness of applying this methot to the circular cascade equipped with a conventional splitter blade. Using this method, in this report, the unsteady forces and moments on the blades of two small-scale cascades, one of which is equipped with main blades and others which are fitted with splitter blades having about two-thirds the chord length of the main blade, are compared with the results obtained by the conventional method. The former is in fairly good agreement with the latter. Also, the fluid dynamic interference effects between the two small-scale cascades were elucidated in detail.
