This mission, known as the Jupiter Icy Moons Orbiter (JIMO), would significantly increase NASA s capability to explore deep space by making use of high power electric propulsion. One electric propulsion option under study for JIMO is an ion propulsion system. An early version of an ion propulsion system was successfully used on NASA's Deep Space 1 mission. One concept for an ion thruster system capable of meeting the current JIMO mission requirement would have individual thrusters that are 16 to 25 kW each and require voltages as high as 8.0 kV. The purpose of this work is to develop power processing schemes for delivering the high voltage power to the spacecraft ion thrusters based upon a three-phase AC distribution system. In addition, a proposed DC-DC converter topology is presented for an ion thruster ancillary supply based upon a DC distribution system. All specifications discussed in this paper are for design convenience and are speculative in nature.

Book excerpt: The high fuel efficiency of electric propulsion makes it a viable alternative for long-distance space travel. Project Prometheus was a NASA-led project that sought to demonstrate that distant electric propulsion missions were achievable by planning an expedition to characterize the Jovian moons of Jupiter. Several requirements were estimated for the electric propulsion system to allow this mission to happen under the budget and technological constraints of the time. Although the mission was terminated early in 2005, many of the design choices during Project Prometheus have affected future long-distance electric propulsion missions. In this thesis the design choices in response to the given constraints in the electric propulsion system are analyzed and evaluated. More specifically, the areas explored include the restriction in the the amount of propellant mass, the choice of propellant used, the specific impulse and power of the thrusters, and the lifetime of the thrusters.

This book was released on 2018-06-24 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: During 2004, the Jupiter Icy Moons Orbiter project, a part of NASA's Project Prometheus, continued efforts to develop electric propulsion technologies. These technologies addressed the challenges of propelling a spacecraft to several moons of Jupiter. Specific challenges include high power, high specific impulse, long lived ion thrusters, high power/high voltage power processors, accurate feed systems, and large propellant storage systems. Critical component work included high voltage insulators and isolators as well as ensuring that the thruster materials and components could operate in the substantial Jupiter radiation environment. A review of these developments along with future plans is discussed. Glenn Research Center NASA/TM-2004-213290, Paper AIAA 2004-3449, E-14737

Download or read book Priorities in Space Science Enabled by Nuclear Power and Propulsion written by National Research Council and published by National Academies Press. This book was released on 2006-03-20 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2003, NASA began an R&D effort to develop nuclear power and propulsion systems for solar system exploration. This activity, renamed Project Prometheus in 2004, was initiated because of the inherent limitations in photovoltaic and chemical propulsion systems in reaching many solar system objectives. To help determine appropriate missions for a nuclear power and propulsion capability, NASA asked the NRC for an independent assessment of potentially highly meritorious missions that may be enabled if space nuclear systems became operational. This report provides a series of space science objectives and missions that could be so enabled in the period beyond 2015 in the areas of astronomy and astrophysics, solar system exploration, and solar and space physics. It is based on but does not reprioritize the findings of previous NRC decadal surveys in those three areas.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this letter is to forward the Prometheus preconceptual Instrumentation and Control (I & C) system architecture (Enclosure (1)) to NR for information as part of the Prometheus closeout work. The preconceptual 1 & C system architecture was considered a key planning document for development of the I & C system for Project Prometheus. This architecture was intended to set the technical approach for the entire I & C system. It defines interfaces to other spacecraft systems, defines hardware blocks for future development, and provides a basis for accurate cost and schedule estimates. Since the system requirements are not known at this time, it was anticipated that the architecture would evolve as the design of the reactor module was matured.

Download or read book Electric Propulsion written by Mariano Andrenucci and published by Academic Press. This book was released on 2022-03-01 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric Propulsion: Concepts and Implementations discusses the core elements of an EP system with classic ion and hall thrusters, also including more recent thrusters (electrothermal, electromagnetic, and magnetoplasmadynamic) and an overview of system aspects affecting interface requirements and constraints. The book concludes with the development of electric micropropulsion and the future of space propulsion. It is ideal for an industrial audience from the aerospace sector who have an engineering or physics background and for specialist roles in propulsion system and component analysis, design and testing, project management, space system engineering, mission analysis and design. Electric propulsion is a widely used technology on spacecraft, with half of all new satellites carrying full electric propulsion. In spite of the advancements over the last decades, there lacks a familiarity with EP thrusters and systems and EP technology mission enabling and enhancing benefits. This book provides these concepts in their latest developments such as hall thrusters and the broadening range of EP applications, both at lower (microsats) and larger (exploration, space transportation) power levels. Describes other electric thrusters developed over the last 50 years and their performance requirements Includes propellant and alternative propellants material as well as multi-mode systems Discusses future trends of electric and space propulsion
