  • Thesis the Effects of a Realistic Hollow Cathode
    THESIS THE EFFECTS OF A REALISTIC HOLLOW CATHODE PLASMA CONTACTOR MODEL ON THE SIMULATION OF BARE ELECTRODYNAMIC TETHER SYSTEMS Submitted by Derek M. Blash Department of Mechanical Engineering In partial fulfillment of the requirements For the Degree of Master of Science Colorado State University Fort Collins, Colorado Fall 2013 Master's Committee: Advisor: John D. Williams Thomas H. Bradley Raymond S. Robinson Copyright by Derek Blash 2013 All Rights Reserved Abstract THE EFFECTS OF A REALISTIC HOLLOW CATHODE PLASMA CONTACTOR MODEL ON THE SIMULATION OF BARE ELECTRODYNAMIC TETHER SYSTEMS The region known as Low-Earth Orbit (LEO) has become populated with artificial satel- lites and space debris since humanities initial venture into the region. This has turned LEO into a hazardous region. Since LEO is very valuable to many different countries, there has been a push to prevent further buildup and talk of even deorbiting spent satellites and de- bris already in LEO. One of the more attractive concepts available for deorbiting debris and spent satellites is a Bare Electrodynamic Tether (BET). A BET is a propellantless propul- sion technique in which two objects are joined together by a thin conducting material. When these tethered objects are placed in LEO, the tether sweeps across the magnetic field lines of the Earth and induces an electromotive force (emf ) along the tether. Current from the space plasma is collected on the bare tether under the action of the induced emf, and this current interacts with the Earth's magnetic field to create a drag force that can be used to deorbit spent satellites and space debris.

  • 1 Using Eletrodynamic Tethers to Perform Station
    USING ELETRODYNAMIC TETHERS TO PERFORM STATION-KEEPING MANEUVERS IN LEO SATELLITES Thais Carneiro Oliveira(1), and Antonio Fernando Bertachini de Almeida Prado(2) (1)(2) National Institute for Space Research (INPE), Av. dos Astronautas 1758 São José dos Campos – SP – Brazil ZIP code 12227-010,+55 12 32086000, [email protected] and [email protected] Abstract: This paper analyses the concept of using an electrodynamic tether to provide propulsion to a space system with an electric power supply and no fuel consumption. The present work is focused on orbit maintenance and on re-boost maneuvers for tethered satellite systems. The analyses of the results will be performed with the help of a practical tool called “Perturbation Integrals” and an orbit integrator that can include many external perturbations, like atmospheric drag, solar radiation pressure and luni-solar perturbation. Keywords: Electromagnetic Tether, Station-Keeping Maneuver, Orbital Maneuver, Tether Systems, Disturbing Forces. 1. Introduction Space tether is a promising and innovating field of study, and many articles, technical reports, books and even missions have used this concept through the recent decades. An overview of the space tethered flight tests missions includes the Gemini tether experiments, the OEDIPUS flights, the TSS-1 experiments, the SEDS flights, the PMG, TiPs, ATEx missions, etc [1-6]. This paper analyses the potential of using an electrodynamic tether to provide propulsion to a space system with an electric power supply and no fuel consumption. The present work is focused on orbit maintenance and re-boosts maneuvers for tethered satellite systems (TSS). This type of system consists of two or more satellites orbiting around a planet linked by a cable or a tether [7].

    Tether Capture of spacecraft at Neptune a,b b, J. R. Sanmart´ın , J. Pel´aez ∗ aReal Academia de Ingenier´ıa of Spain bUniversidad Polit´ecnica de Madrid, Pz. C.Cisneros 3, Madrid 28040, Spain Abstract Past planetary missions have been broad and detailed for Gas Giants, compared to flyby missions for Ice Giants. Presently, a mission to Neptune using electrodynamic tethers is under consideration due to the ability of tethers to provide free propulsion and power for orbital insertion as well as additional exploratory maneuvering — providing more mission capability than a standard orbiter mission. Tether operation depends on plasma density and magnetic field B, though tethers can deal with ill-defined density profiles, with the anodic segment self-adjusting to accommodate densities. Planetary magnetic fields are due to currents in some small volume inside the planet, magnetic-moment vector, and typically a dipole law approximation — which describes the field outside. When compared with Saturn and Jupiter, the Neptunian magnetic structure is significantly more complex: the dipole is located below the equatorial plane, is highly offset from the planet center, and at large tilt with its rotation axis. Lorentz-drag work decreases quickly with distance, thus requiring spacecraft periapsis at capture close to the planet and allowing the large offset to make capture efficiency (spacecraft-to-tether mass ratio) well above a no-offset case. The S/C might optimally reach periapsis when crossing the meridian plane of the dipole, with the S/C facing it; this convenient synchronism is eased by Neptune rotating little during capture. Calculations yield maximum efficiency of approximately 12, whereas a 10◦ meridian error would reduce efficiency by about 6%.

  • Electrodynamic Tethers in Space
    Electrodynamic Tethersin Space By Enrico Lorenzini and Juan Sanmartín 50 SCIENTIFIC AMERICAN AUGUST 2004 COPYRIGHT 2004 SCIENTIFIC AMERICAN, INC. ARTIST’S CONCEPTION depicts how a tether system might operate on an exploratory mission to Jupiter and its moons. As the apparatus and its attached research instruments glide through space between Europa and Callisto, the tether would harvest power from its interaction with the vast magnetic field generated by Jupiter, which looms in the background. By manipulating current flow along the kilometers-long tether, mission controllers could change the tether system’s altitude and direction of flight. By exploiting fundamental physical laws, tethers may provide low-cost electrical power, drag, thrust, and artificial gravity for spaceflight www.sciam.com SCIENTIFIC AMERICAN 51 COPYRIGHT 2004 SCIENTIFIC AMERICAN, INC.

  • Applications of the Electrodynamic Tether to Interstellar Travel

MATLOFF Dept. of Physical & Biological Sciences, New York City College of Technology, CUNU, 300 Jay Street, Brooklyn, NY 11201, USA Gray Research Inc., 675 Discovery Drive, Suite 302, Huntsville, AL, 35806, USA Email: [email protected] and LES JOHNSON In-Space Propulsion Technology Project, NASA Marshall Space Flight Center, NP40, AL, 35812, USA Emai 1: C. Les.Johnson @ nasa. gov ABSTRACI’: After considering relevant properties of the local interstellar medium and defining a sample interstellar mission, this paper considers possible interstellar applications of the electrodynamic tether, or EDT. These include use of the EDT to provide on-board power and affect trajectory modifications and direct application of the EDT to starship acceleration. It is demonstrated that comparatively modest EDTs can provide substantial quantities of on-board power, if combined with a large-area electron- collection device such as the Cassenti toroidal-field ramscoop. More substantial tethers can be used to accomplish large-radius thrustless turns. Direct application of the EDT to starship acceleration is apparently infeasible. Keywords: interstellar travel, tethers, world ships, ramscoops, thrustless turning, on- board power sources 1. Introduction: The Electrodynamic Tether, or EDT, is conceptually one of the simplest in-space propulsion concepts. The tether consists of a long, conducting strand. Electrons are collected from the ambient plasma at one end, flow along the tether, and are emitted at the other end of the tether. In certain cases, the tether itself collects electrons from the local plasma, and a dedicated electron-collection device is not required.
