  • Magnetoshell Aerocapture: Advances Toward Concept Feasibility
    Magnetoshell Aerocapture: Advances Toward Concept Feasibility Charles L. Kelly A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Aeronautics & Astronautics University of Washington 2018 Committee: Uri Shumlak, Chair Justin Little Program Authorized to Offer Degree: Aeronautics & Astronautics c Copyright 2018 Charles L. Kelly University of Washington Abstract Magnetoshell Aerocapture: Advances Toward Concept Feasibility Charles L. Kelly Chair of the Supervisory Committee: Professor Uri Shumlak Aeronautics & Astronautics Magnetoshell Aerocapture (MAC) is a novel technology that proposes to use drag on a dipole plasma in planetary atmospheres as an orbit insertion technique. It aims to augment the benefits of traditional aerocapture by trapping particles over a much larger area than physical structures can reach. This enables aerocapture at higher altitudes, greatly reducing the heat load and dynamic pressure on spacecraft surfaces. The technology is in its early stages of development, and has yet to demonstrate feasibility in an orbit-representative envi- ronment. The lack of a proof-of-concept stems mainly from the unavailability of large-scale, high-velocity test facilities that can accurately simulate the aerocapture environment. In this thesis, several avenues are identified that can bring MAC closer to a successful demonstration of concept feasibility. A custom orbit code that dynamically couples magnetoshell physics with trajectory prop- agation is developed and benchmarked. The code is used to simulate MAC maneuvers for a 60 ton payload at Mars and a 1 ton payload at Neptune, both proposed NASA mis- sions that are not possible with modern flight-ready technology. In both simulations, MAC successfully completes the maneuver and is shown to produce low dynamic pressures and continuously-variable drag characteristics.

Mantenieks NASA Lewis Research Center Cleveland, OH 44135 Michael R. l.atPointe Sverdrup Technology, Inc. NASA Lewis Research Center Group Brook Park, OH 44142 Abstract MPD thrusters have demonstrated between 2000 and 7000 seconds specific impulse at efficiencies approaching 40 %, and have been operated continuously at power levels over 500 kW. These demonstrated capabilities, combined with the simplicity and robustness of the thruster, make them attractive candidates for application to both unmanned and manned orbit raising, lunar, and planetary missions. To date, however, only a limited number of thruster confiurations, propellants, and operating conditions have been studied. This work reviews the present status of MPD thruster research, including developments in the _ performance levels and electrode erosion rates, and theoretical studies of the thruster dynamics. Significant progress has been made in establishing empirical scaling laws, performance and lifetime limitations and in the development of numerical codes to simulate the flow field and electrode processes.

  • Revolutionary Propulsion Research at Tu Dresden
    67 REVOLUTIONARY PROPULSION RESEARCH AT TU DRESDEN M. Tajmar Institute of Aerospace Engineering, Technische Universit¨at Dresden, 01062 Dresden, Germany Since 2012, a dedicated breakthrough propulsion physics group was founded at the Institute of Aerospace Engineering at TU Dresden to investigate revolutionary propulsion. Most of these schemes that have been proposed rely on modifying the inertial mass, which in turn could lead to a new propellantless propulsion method. Here, we summarize our recent e↵orts targeting four areas which may provide such a mass modification/propellantless propulsion option: Asymmetric charges, Weber electrodynamics, Mach’s principle, and asymmetric cavities. The present status is outlined as well as next steps that are necessary to further advance each area. 1. INTRODUCTION Present-day propulsion enables robotic exploration of our solar system and manned missions limited to the Earth-Moon distance. With political will and enough resources, there is no doubt that we can develop propulsion technologies that will enable the manned exploration of our solar system. Unfortunately, present physical limitations and available natural resources do in fact limit human ex- ploration to just that scale. Interstellar travel, even to the next star system Alpha Centauri, is some 4.3 light-years away which is presently inaccessible – on the scale of a human lifetime. For example, one of the fastest manmade objects ever made is the Voyager 1 spacecraft that is presently traveling at a velocity of 0.006% of the speed of light [1]. It will take some 75,000 years for the spacecraft to reach Alpha Centauri. Although not physically impossible, all interstellar propulsion options are rather mathematical exercises than concepts that could be put into reality in a straightforward manner.

It is shown that the need for research is driven both by the application as well as relative maturity of the technology. For flight qualified systems such as moderately-powered Hall thrusters and gridded ion thrusters, there are open questions related to testing fidelity and predictive modeling. For less developed technologies like large-scale electrospray arrays and pulsed inductive thrusters, the challenges include scalability and realizing theoretical performance. Strategies are discussed to address the challenges of both mature and developed technologies. With the aid of targeted numerical and experimental facility effects studies, the application of data-driven analyses, and the development of advanced power systems, many of these hurdles can be overcome in the near future. Keywords: electric propulsion; Hall effect thruster; gridded ion thruster; electrospray; magnetic nozzle; pulsed inductive thruster 1. Introduction The use of electric propulsion (EP) for space applications is currently undergoing a rapid expansion. There are hundreds of operational spacecraft employing EP technologies with industry projections showing that nearly half of all commercial launches in the next decade will have a form of electric propulsion. In light of their widespread use, the thruster types that have fueled this expansion—moderately-powered (1–20 kW) Hall effect, electrothermal, and ion thrusters—arguably have now achieved “mature” operational status.

  • Investigation of the Gem Mpd Thruster Using the Mach2 Magnetohydrodynamics Code
    INVESTIGATION OF THE GEM MPD THRUSTER USING THE MACH2 MAGNETOHYDRODYNAMICS CODE BY DREW AHERN THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Aerospace Engineering in the Graduate College of the University of Illinois at Urbana-Champaign, 2013 Urbana, Illinois Adviser: Professor Rodney L. Burton Abstract This work investigated using the MACH2 plasma simulation code in replicating the results of previous experimental work on the gallium electromagnetic (GEM) thruster. MACH2 was also used to examine possible changes to the GEM thruster that could improve the performance of the actual thruster. Thruster radius ratios of 3.4 and 5 were examined, and a mass flow rate of 6 g/s was specified for each. In this study, several properties were examined and compared with the experimental GEM thruster. A voltage of 148 V was computed for the GEM thruster with a radius ratio of 3.4, and a voltage of 222 V was computed for a thruster with a radius ratio of 5. Electron density and axial velocity values were analyzed and compared with experimental data. The simulated magnetic field near the cathode was shown to be very close to experimental measurements. Pressure simulation results were assessed, which indicated the presence of an electrothermal thrust component. Temperatures were observed and compared, and the electrical conductivity was examined. A momentum flow rate parameter was derived to examine thrust values, and results of 124 N and 131 N with thruster efficiencies of 38% and 28% were calculated for the radius ratios of 3.4 and 5, respectively.

  • Liquid Oxygen Augmented Gas Core Nuclear Thermal Rocket
    Advances in Aerospace Science and Applications. ISSN 2277-3223 Volume 3, Number 3 (2013), pp. 239-244 © Research India Publications http://www.ripublication.com/aasa.htm Liquid Oxygen Augmented Gas Core Nuclear Thermal Rocket V. Krishnamurthy1 and A. Vignesh2 1,2Department of Aeronautical Engineering Rajalakshmi Engineering College Chennai-602105, Tamil Nadu, India. Abstract Conventional propulsion technology (chemical and electric) currently limits the possibilities for human space exploration to the neighborhood of the Earth. If farther destinations (such as Mars) are to be reached with humans on board, a more capable interplanetary transfer engine featuring high thrust and high specific impulse is required. The source of energy which could in principle best meet these engine requirements is nuclear thermal energy. So an innovative gas core nuclear thermal rocket concept which combines conventional liquid hydrogen cooled nuclear thermal rocket and supersonic combustion ramjet (scramjet) technologies is described. Known as the Liquid oxygen augmented Gas core Nuclear Thermal Rocket (LAG- NTR), this concept utilizes the large divergent section of the gas core nuclear thermal rocket’s nozzle as an afterburner into which liquid oxygen is injected and supersonically combusted with nuclear preheated hydrogen emerging from the LAG-NTR’s choked sonic throat- scramjet propulsion in reverse. By varying the oxygen-to- hydrogen mixture ratio, the LAG-NTR can operate over a wide range of thrust and specific impulse values while the gaseous core reactor’s power level remains relatively constant. This thrust augmentation feature means that a larger engine performance can be obtained with a comparatively smaller LAG-NTR engine. Keywords: Nuclear thermal rocket, gas core, afterburner, scramjet, thrust, specific impulse, supersonic combustion.

  • Current Status of NASA Evolutionary Xenon Thruster - Commercial (NEXT-C)
    47th Lunar and Planetary Science Conference (2016) 1786.pdf Current Status of NASA Evolutionary Xenon Thruster - Commercial (NEXT-C). M. Dolloff1 and J. Jackson2, 1NASA – Glenn Research Cetner ([email protected]), 2Aerojet Rockedyne ([email protected]) Introduction: The NASA’s Evolutionary Xenon Thruster (NEXT) ion propulsion technology was devel- oped by the NASA In-Space Propulsion Technology Project, within the Science Mission Directorate (SMD), for use in a wide array of planetary science missions in- cluding Discovery, New Frontiers and Flagship classes. A NEXT ion propulsion system consists of a gridded ion thruster, Power Processing Unit (PPU), thruster gimbal, a xenon propellant feed system, and a control interface captured either in a dedicated unit or distributed be- tween the ion propulsion system and the spacecraft. NEXT has very high fuel efficiency and flexible opera- tions making it ideal for many classes of science mis- sions. NASA’s Planetary Sceince Division (PSD) has committed to the completion of the flight fidelity de- sign, qualification, and fabrication of two PPUs and Thruster for use in future planetary science missions. These two thrusters and PPUs will be available in early 2019, well in advance of use for a New Frontiers-4 mis- sion. In addition to developing the two flight thrusters and PPUs for near-term use, NASA has a goal of NEXT be- coming a commercial product for purchase by NASA and non-NASA customers. Aerojet Rocketdyne, and their major sub-contractor ZIN Technologies, was se- lected through a competitive process to perform this work and retains the rights to produce the system, known as NEXT-C for future commercialization.
