1719 Advantages of a Tandem Bladed Inducer

Abstract

An inducer is usually utilized in a rocket turbopump system to increase pump suction performance. According to this point, high suction performance is the principal function for an inducer. However, in high performance rocket turbopump system for recent rocket engines, high pressure rise is required for an impeller. The purpose of this article is to clarify the advantages of a tandem bladed inducer which is recommended for high head rise inducer by NASA criteria for a design of a rocket turbopump system.
