Abstract
A high pressure engine propulsion system, such as a rocket engine, having improved engine performance is described herein. A liquid propellant, such as liquid oxygen, is paramagnetic. Cavitation bubbles of the liquid propellant can form in an inducer tunnel of a turbopump when the pressure in the turbopump inlet drops below the vapor pressure of the liquid propellant. The turbopump includes a magnetic field source external to the inducer tunnel to generate or provide a steady magnetic field across or through the inducer tunnel. The steady magnetic field interacts with the paramagnetic propellant, thereby reducing or eliminating cavitation bubble growth, causing cavitation bubbles to collapse, retaining cavitation bubbles within the inducer tunnel, the like, or combinations thereof.
