Abstract

See full text

A rocket engine propulsion system having improved engine performance is described herein. The rocket engine propulsion system includes an axial counterbalance to reduce or eliminate axial thrust exerted on components of a turbopump. The axial counterbalance can allow for a larger range of axial thrust forces while coupling this ability to a rotational speed (e.g., rotations per minute, or RPM) of a shaft. The axial counterbalance includes a protrusion on that extends circumferentially around a shaft that mates with a protrusion on a swing arm. The swing arm is rotatably attached to a bracket which is constrained by a static support.
