An Optimization Approach to Hybrid Electric Propulsion System Design
Environmentally friendly ground vehicles with range and performance capabilities surpassing those of conventional ones require a careful balance among competing goals for fuel efficiency, performance, and emissions. One research activity at the Automotive Research Center is to integrate hybrid electric vehicle simulations with high-fidelity engine modules to increase the accuracy of predictions...
متن کاملModeling and Control of a Hybrid Hydraulic-Electric Propulsion System
The utilization of renewable energies as an alternative for fossil fuels is considerably growing due to an increasing environmental concern and exhaustion of fossil fuels [1-3]. Transportation electrification is one way to replace or reduce fossil fuels with renewable energy sources. Several propulsion systems including hybrid electric vehicles and plug in hybrid electric vehicles have been int...
متن کاملModelling Electric Propulsion Plume Interactions
Electric propulsion is currently being planned for use on several future deep space missions. It has long been recognized that the exhaust plume from an electric thruster can induce a complex set of plasma interaction and hence both science and engineering concerns have been raised. This paper first presents an overview of our current understanding of electric propulsion plume interactions and ...
متن کاملSpacecraft Electric Propulsion—An Overview
A short review of the status of electric propulsion (EP) is presented to serve as an introduction to the more specialized technical papers also appearing in this Special Issue (Journal of Propulsion and Power, Vol. 14, No. 5, Sept. –Oct. 1998). The principles of operation and the several types of thrusters that are either operational or in advanced development are discussed rst, followed by s...
متن کاملSimulation of Electric Propulsion Thrusters
Electric propulsion thrusters are replacing small chemical thrusters used for spacecraft control and orbital maneuvers. These thrusters use a variety of mechanisms to convert electrical power into thrust and in general provide superior specific impulse in comparison to chemical systems. Electric propulsion has been under development for the last fifty years, and almost all thrusters are designe...
