Abstract Pogo is a longitudinal vibration of liquid rockets, which is considered as a fluid-structure coupling of liquid supply system and rocket's structure. Its suppression is a critical element in the design of the fluid piping systems in liquid rockets, for many of them have been reported suffering the pogo vibration worldwide. Pogo suppression is a systematic technology including fluid-structure modelling, stability analysis and suppression devices. The suppression methods for pogo attracted much attention in the 1960s–1980s, while rare review can be found in recent decades. This article is to review pogo suppression methods vastly, and find effective and potential approaches for the future. The research and experience on the suppression technologies of pogo are investigated comprehensively, including the passive and active schemes. The advantages and limitations of various methods are discussed carefully, which indicates that the suppression is a systematic consideration. Moreover, the progress of the active control of fluid pulsation in hydraulic systems is also introduced detailedly, expecting a combination with the pogo application.
