Providing stability and dynamic quality of fuel systems is very important problem when developing and during operation of power plants in many applications. For example, it is critical issue for longitudinal stabilization of launch vehicles (pogo attenuation). One of effective ways to provide rocket longitudinal stability is installation of a pogo suppression device (PSD) in the feed line. The paper presents a mathematical model of the gas PSD, its transient and frequency responses that can be used for the fuel system design. For developing mathematical model of the PSD, analytical methods and numerical simulation were applied, the software packages MatLab/Simulink and AMESim being used. The PSD input acoustic admittance was calculated. The developed model of the gas PSD can be used in the mathematical model of the fuel line when solving problem of longitudinal stability of launch vehicles and other issues of power plants design.
