Download or read book Colloid Thrusters Physics Fabrication and Performance written by and published by . This book was released on 2005 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document summarizes the results of 3 and 1/2 years of work by our team on the basic physics and technology required for the development of Colloid Thrusters (also called more recently Electrospray Thrusters). The research covered the basic physics of operation in the mixed ion-droplet mode, later extended to the newly discovered pure ionic mode, the microfabrication in Silicon of two types of arrays of colloid or electrospray emitters, and the development of a quantitative theory for the colloidal regime (no ions). This Executive Summary describes briefly the various achievements, with reference to our interim Reports and to our publications. Special emphasis is placed on the results that were obtained during the one-year extension (2004), which were not covered in our interim reports. The Theses, published papers and Conference papers for 2004 are enclosed in a companion CD disk; earlier Theses and publications were similarly attached to previous Reports.

Download or read book Fundamentals of Electric Propulsion written by Dan M. Goebel and published by Wiley. This book was released on 2008-11-10 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.

This book was released on 2004 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) variations of an externally fed planar electrospray thruster array (with the ionic liquid EMI-BF4 as propellant-intended to work in the solvated ion emission regime). For the case of the linear colloid thruster array, it was possible to demonstrate cumulative emission uniformity and steady-uniform operation of the modular units (set of emitters fed by the same manifold), using the imprints of the exit stream on a collector. Both results are in agreement with theoretical models. Current versus flowrate dependence in agreement with the theoretical model of single Taylor cone-droplet emission was also demonstrated. It was experimentally found that he propellant doping level strongly influences its wettability with respect to the engine internal surface. As a consequence of this effect, engines that were brought to steady emission showed arcing because of bursting events during operation. The proposed electrical flow control was experimentally verified. In the case of the planar electrospray thruster array, uniform-steady emission was demonstrated for two types of emitter geometries using experimental impact traces on a collector and current versus voltage measurements. It was also shown that there is a strong dependence of the emitted current on temperature. Contributions of this work also include several novel fabrication techniques, particularly a process to generate black silicon using a chlorine-based plasma, a process to generate mesoscale uniform etching for silicon, a technique to anisotropically pattern thick silicon oxide films ...

Book excerpt: Space launches have evoked the same vivid image for decades: bright orange flames exploding beneath a rocket as it lifts off and thunders into the sky. An alternative acceleration system could reshape that vision forever, with rockets leaving their energy source on the ground... or in space. Laser Propulsion in Space: Fundamentals, Technology, and Future Missions takes readers on a comprehensive journey from the theoretical overview of propulsion fundamentals, to reviews of current projects involving high-power CW fiber lasers and energetic mm-wave sources with their ongoing and potential end-use applications in beamed energy propulsion (BEP). Written by experts in the field, this mathematically sound reference text also highlights graphical solutions of equations’ results, as well as case studies with worked-out examples, making this book an invaluable compendium for students, researchers, technology developers and futurists in understanding the promise and challenges of this emerging technology. Covers beamed energy propulsion advances Highlights state-of-the-art BEP applications of LEO debris removal, suborbital and orbital launch, solar system exploration, and interstellar lightsail probes, as well as advances in related photon source technologies and infrastructures Includes opinion sections explaining why we as a technical society should care about each chapter’s topic and the considerably good outcomes that can be achieved with laser engines Is accompanied by a website with video clips and other ancillary materials to enhance insight
