Turbopump Magnetic Torque Generator for Intermediate Regime Control

The patent replaces conventional mechanical control systems (flow restriction valves, mechanical governors) with a magnetic torque generator that uses electromagnetic fields to apply controlled torque to the drive shaft. This substitution enables precise torque control in intermediate operating regimes where conventional mechanical controls cannot maintain stability, allowing the turbopump to operate stably between standby and nominal regimes without converging to extreme states.

The patent implements a control system that continuously monitors the turbopump's operating state and adjusts the magnetic torque generator's output accordingly. This feedback mechanism enables precise control of the transition between standby and nominal regimes by applying appropriate torque to counteract thermodynamic energy inputs that would otherwise cause convergence to nominal regime, allowing stable operation at intermediate speeds.

The magnetic torque generator is designed to perform multiple functions: it provides controlled torque for regime transitions, acts as a magnetic bearing to support the drive shaft, and enables precise speed control in intermediate regimes. By consolidating these functions into a single integrated component rather than adding separate mechanical controls, the patent reduces overall system complexity while achieving superior adaptability.

The magnetic torque generator utilizes the same electromagnetic field mechanism to provide both torque control and bearing support functions. The magnetic field that generates torque also creates the holding effect that prevents drive shaft contact with mechanical bearings, reducing wear. This self-service approach eliminates the need for separate magnetic bearing systems, thereby avoiding additional energy consumption that would result from redundant systems.
