Download or read book MEMS and Microstructures in Aerospace Applications written by Robert Osiander and published by CRC Press. This book was released on 2018-10-03 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The promise of MEMS for aerospace applications has been germinating for years, and current advances bring the field to the very cusp of fruition. Reliability is chief among the challenges limiting the deployment of MEMS technologies in space, as the requirement of zero failure during the mission is quite stringent for this burgeoning field. MEMS and Microstructures in Aerospace Applications provides all the necessary tools to overcome these obstacles and take MEMS from the lab bench to beyond the exosphere. The book begins with an overview of MEMS development and provides several demonstrations of past and current examples of MEMS in space. From this platform, the discussion builds to fabrication technologies; the effect of space environmental factors on MEMS devices; and micro technologies for space systems, instrumentation, communications, thermal control, guidance navigation and control, and propulsion. Subsequent chapters explore factors common to all of the described systems, such as MEMS packaging, handling and contamination control, material selection for specific applications, reliability practices for design and application, and assurance practices. Edited and contributed by an outstanding team of leading experts from industry, academia, and national laboratories, MEMS and Microstructures in Aerospace Applications illuminates the path toward qualifying and integrating MEMS devices and instruments into future space missions and developing innovative satellite systems.

Book Synopsis Theoretical Modeling and Optimization of Ablation-fed Pulsed Plasma Thrusters by : Yiangos George Mikellides
Download or read book Theoretical Modeling and Optimization of Ablation-fed Pulsed Plasma Thrusters written by Yiangos George Mikellides and published by . This book was released on 1999 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Theoretical modeling of ablation-fed, pulsed plasma thrusters (PPTs) with the MACH2 code has shown that after repeated pulsed operation, the total expelled mass is due to ablation during the discharge and solid decomposition that persists long after the pulse. The latter mass does not considerably contribute to the impulse-bit thus degrading thruster performance. For the rectangular PPT geometry, optimizing current waveforms in combination with channel widths are presented, that utilize all decomposed mass, electromagnetically. These waveforms are characterized by short rise times (1 [mu]sec) and prolonged decays (25 [mu]sec). Simplified modeling based on steady-state, one-dimensional flow reveals that the mass flow rate varies linearly with the square of the magnetic field and that the downstream flow speed is driven towards the Alfven wave speed when the magnetic pressure is much greater than the gasdynamic pressure. The model has been confirmed by MACH2. The mass flow requirement for such magnetosonic flow in turn, determines the surface temperature of the solid.

Book Synopsis A Performance Comparison of Pulsed Plasma Thruster Electrode Configurations by : National Aeronautics and Space Administration (NASA)
Download or read book A Performance Comparison of Pulsed Plasma Thruster Electrode Configurations written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-08-09 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pulsed plasma thrusters are currently planned on two small satellite missions and proposed for a third. In these missions, the pulsed plasma thruster's unique characteristics will be used variously to provide propulsive attitude control, orbit raising, translation, and precision positioning. Pulsed plasma thrusters are attractive for small satellite applications because they are essentially stand alone devices which eliminate the need for toxic and/or distributed propellant systems. Pulsed plasma thrusters also operate at low power and over a wide power range without loss of performance. As part of the technical development required for the noted missions, an experimental program to optimize performance with respect to electrode configuration was undertaken. One of the planned missions will use pulsed plasma thrusters for orbit raising requiring relatively high thrust and previously tested configurations did not provide this. Also, higher capacitor energies were tested than previously tried for this mission. Multiple configurations were tested and a final configuration was selected for flight hardware development. This paper describes the results of the electrode optimization in detail. Arrington, Lynn A. and Haag, Tom W. and Pencil, Eric J. and Meckel, Nicole J.

This book was released on 1981 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Teflon pulsed thruster is being considered as an attitude control and station-keeping device for spacecraft and satellites. In determining the compatibility of the pulsed plasma thruster with spacecraft systems, it is necessary to assess the potentially harmful effects the exhaust products may have on various spacecraft surfaces. Previous efforts to acquire data in space environmental chambers have had limited success due to the interferences caused by exhaust products scattering from the test facility walls and pumping panels. The overall objective of this effort is to define the operating characteristics of prototype pulsed plasma engine and a test facility configuration suitable for contamination-type tests. The immediate objectives of this report are: (1) to use a micropound and a millipound pulsed plasma engine to obtain information on the species in the plasma and how they react when they encounter the test chamber walls, and (2) to examine the effectiveness of possible diagnostic techniques; these include witness plates, electron multipliers, mass spectrometers, Faraday cups, attenuated total reflectance (ATR) plates, calorimeters, and UV spectroscopy.

Available in PDF, EPUB and Kindle. Book excerpt: The laser ablation plasma thruster is a novel electric propulsion thruster, which combined the laser ablation and electromagnetic acceleration. In order to investigate the plasma expansion and ionization in the laser ablation plasma thruster, which was difficult to obtain from experiments, the heat conduction model and fluid dynamics model were established. The heat conduction model was established to calculate the target ablation, taking into account temperature-dependent material properties, phase transition, dielectric transition and phase explosion. The fluid dynamics model was used to calculate the plasma properties, taking into account ionization, plasma absorption and shielding. The ablation plasma velocity, temperature and electron number density were predicted by using the numerical method. The calculated results showed that the peak values of ablation plasma velocity, temperature and electron number density fraction were distributed at the front of the plasma plume. Moreover, the discharge characteristics and thrust performance were tested with different charged energy, structural parameters and propellants. The thrust performance was proven to be improved by electromagnetic acceleration.
