Magnetic advanced generation jet electric turbine

Abstract

Supersonic Magnetic Advanced Generation Jet Electric Turbine (S-MAGJET) described herein, and a subsonic derivative, MAGJET, integrate a gas power turbine, superconducting electric power and propulsion generation, and magnetic power flux field systems along with an ion plasma annular injection combustor which utilizes alternative petroleum-based fuel and combustion cycles to create a hybrid turbine turbomachine for aerospace propulsion. The propulsion unit is able to achieve a dramatic increase in horsepower, combustion and propulsion efficiency, and weight reduction. In addition, the turbomachinery structures may be disposed within an exoskeleton architecture that achieves an increase in thrust to weight ratio with a concomitant increase in fuel efficiency and power generation. The engine continuously adjusts the temperature, pressure and mass airflow requirements using an electromagnetic power management system architecture. Engine performance may be controlled across the entire desired flight envelope, whether subsonic, transonic or supersonic flight conditions.

AI Technical Summary

Benefits of technology

The patent describes a new type of jet engine that combines gas power, superconducting electric power, and magnetic power to create a hybrid turbine turbomachine for aerospace propulsion. The engine is designed to achieve a dramatic increase in power, combustion, and propulsion efficiency, and weight reduction. It uses an ion plasma annular injection combustor that can operate with alternative petroleum-based fuel and combustion cycles. The engine performance is controlled across the entire desired flight envelope, and it maximizes propulsion efficiencies over a broader range of operating conditions compared to current art of turbine technology. The engine architecture is more efficient than current designs, and it uses a hollow-core shaftless tunnel to carry additional bypass air, which is a more efficient method of producing thrust for propulsion. Overall, the S-MAGJET provides a flight operation envelope with little or no off-design flight condition, and it is designed to achieve maximum efficiency and power generation across the entire desired flight envelope.

Problems solved by technology

In addition, the DOD and Armed Services are now demanding significant increases in electric output from turbine flight engines.

Future aircraft concepts are demanding in excess of 1.0 megawatt of power which current turbine engine companies cannot deliver off of their present engine designs, largely because they are restricted by the reduction performance of gear boxes, drive shafts and the generator added on as an additional component which is not made by the OEM engine supplier.

These systems are quite heavy and typically limit the thrust to weight ratios to not more than 7 to 1.
