It also has enough length of parallel flow both upstream and downstream of the blade rows. Rotor discs, four in all, are to be driven independently to each other. Experiments were carried out with two counter-rotating blade rows attached to this compressor. Under certain operating conditions the flow pattern of rotating stall was brought to rest, and detailed measurements of the flow such as distributions of velocities and static pressures were performed through the whole flow fields. Thus flow conditions just upstream and downstream of each blade row being known, the dynamic performances of the blade row in unsteady flow were estimated, and a clue to the magnitude of the boundary layer time delay was acquired., 資料番号: SA0124371000}, pages = {209--239}, title = {<論文>旋回失速と翼列動特性に関する研究(V/STOL機用エンジンに関する研究)}, volume = {1}, year = {1965} }
