- Abstract
Computational and experimental studies on the comparative performances of forward-sweep and backward-sweep inducers for the Liquid Rocket Engine (LRE) turbopumps are conducted. Computational results show that back flows at the inlet decrease in the case of forward-sweep inducers and the low pressure region at back flow is also decreased, which is presumed to improve the suction performance of the inducers. Experimental results show that the performance of backward-sweep inducers is almost the same as that of the backward-sweep inducers although it has smaller inlet tip diameter and shorter axial length. The efficiency of the forward-type inducer is found better than that of the backward-sweep inducer due to the small size of backflows both in computation and experiment.
