Abstract
The present invention is concerned with an axial-flow or mixed-flow inducer (3) which is disposed upstream of a main impeller (2) for improving the suction capability of a pump such as a turbopump. In the inducer (3), a blade angle (βbt) from a tip (T1) to a hub (H1) at a blade leading edge (31) is substantially the same as an inlet flow angle (β1−t) at a designed flow rate.
