ロケットポンプインデューサの疲労強度

概要

論文の詳細を見る
Various kinds of unsteady phenomena, such as cavitation surge, rotating cavitation, rotating stall, backflow cavitation etc., have occurred in recent rocket pump inducers for booster engines because they are used under the condition of high head, high load and low suction pressure. Therefore, it is very important to estimate unsteady stress on the blades to obtain the required durability of the inducer. An analytical method to obtain the fatigue strength, which utilizes the results of water tests of the inducer, is presented in this paper.
