Abstract
PURPOSE: To improve cascade performance as well as to reduce secondary flow loss which is engendered near to the lateral bulkheads in such a way that accompanied by drawing near to respective lateral bulkheads from the central part of the blade length, the blade front edge can be protruded toward the upstream side within a settled extent.
CONSTITUTION: A blade divided into limited length by upper and lower lateral bulkheads 12a, 12b is constituted in such a way that accompanied by drawing near to respective lateral bulkheads 12a, 12b from the central part of the blade length direction, a blade front edge 11c can gradually protrude toward the upstream side without expanding the blade width. Said constitution facilitates that pressure difference in the blade direction of the blade rear side changes the ratic α1/h1, α2/h2 of front edge protruding extent r1, r2 to front edge protruding distance α1, α2, and can yield optional pressure difference ΔPs1, ΔPs2. This facilitates to display preventive effects in commensuration to the size of the secondary flow
