Hybrid electric chemical propulsion
21st Joint Propulsion Conference, 1985Abstract : A spacecraft propulsion concept that uses a combination of electrical energy and chemical energy for thrust is explored using thermodynamic modeling calculations. The essence of this concept consists of adding a carefully chosen amount of O2 or F2 oxidizer to the propellant flow of a conventional H2 electrothermal thruster.

Electric and Hybrid-Electric Propulsion Systems
2013While in conventional ICE-based vehicles the energy carrier is a fossil fuel, electric and hybrid-electric propulsion systems are characterized by the presence of an electrochemical or electrostatic energy storage system. Moreover, at least one electric motor is responsible — totally or partially — for the vehicle propulsion.

Hybrid electric propulsion system using submersed SPM machine
2008 18th International Conference on Electrical Machines, 2008This paper deals with the design of a surface-mounted permanent magnet (SPM) motor operating in a propulsion system of a small ship. The SPM motor is installed in a submersed bulb provided of a propeller. The particular location of the motor together with the very high torque-to-volume ratio required by this application need an accurate coupled ...
