Abstract
The self-exciting oscillations in LRE propellants supply systems can provoke resonance oscillations of engine design elements and breakdown of some its units. They can also influence longitudinal stability of rockets, since their frequency values are usually close to a frequence range of longitudinal oscillation first modes for elastic bodies of liquid propellant launchers.
In order to increase stability of LRE propellants supply system and longitudinal stability of launchers a special design of screw inducer (screw with radial slots in each blade) has been developed that allow to suppress the cavitation self-exciting oscillations very effectively.
