Book Synopsis Beamed-Energy Propulsion (Bep) Study by : National Aeronautics Administration
Download or read book Beamed-Energy Propulsion (Bep) Study written by National Aeronautics Administration and published by CreateSpace. This book was released on 2014-11-15 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: The official scope of this study was (1) to review and analyze the state-of-art in beamed-energy propulsion (BEP) by identifying potential game-changing applications, (2) to formulate a roadmap of technology development, and (3) to identify key near-term technology demonstrations to rapidly advance elements of BEP technology to Technology Readiness Level (TRL). The two major areas of interest were launching payloads and space propulsion. More generally, the study was requested and structured to address basic mission feasibility. The attraction of BEP is the potential for high specific impulse (Isp) while removing the power generation mass. The rapid advancements in high-energy beamed-power systems and optics over the past 20 years warranted a fresh look at the technology. BEP could help meet the known needs of NASA and/or the Department of Defense (DOD), providing low-cost, rapid access to space for operationally responsive military systems, scientific payloads, and the commercialization of space. For launching payloads, the study concluded that using BEP to propel vehicles into space is technically feasible if a commitment to develop new technologies and large investments can be made over long periods of time. Such a commitment would include specific technologies like multi-megawatt power lasers and microwave sources as well as building new launch facility infrastructure. The costs of the infrastructure are high. From a commercial competitive standpoint, if an advantage of beamed energy for Earth-to-orbit (ETO) is to be found, it will rest with smaller, frequently launched payloads. For space propulsion, the study concluded that using beamed energy to propel vehicles from low Earth orbit to geosynchronous Earth orbit (LEO-GEO) and into deep space is definitely feasible and showed distinct advantages and greater potential over current propulsion technologies. However, this conclusion also assumes that upfront infrastructure investments and commitments to critical technologies will be made over long periods of time. BEP energy source requirements are much less than for the launch applications. Lower propulsion costs with shorter transit times for LEO-GEO servicing missions and faster science missions to the outer planets are the major benefits. The chief issue, similar to that for payloads, is high infrastructure costs. As can happen in detailed examinations of innovative approaches, the study uncovered two unanticipated areas that appear to have great potential and therefore are worthy of consideration for new investment, at least at the "detailed study" level. BEP could provide the key to combining propulsion, power, and communications systems for in-space applications, thus creating a new class of small spacecraft with minimal systems and reducing their complexity, cost, and mass. Beaming energy to a thermal optical plasma engine could provide a highly efficient technology for high-thrust and high-ISP space propulsion. The specifics of these concepts are provided in the main body of the report. Finally, the intention of this study was to work within the time and resources allotted to determine the feasibility of BEP. This involved achieving a single closed-design solution for each mission analyzed which is, in all probability, not the optimum solution. As such, proponents of the investigated concepts may not agree with the study's findings and final design solutions, citing that better performance could be achieved with additional design effort. The authors do not disagree with that perspective. Nonetheless, the study management team was satisfied that the results were sufficient to meet the primary objective, which was to prove or disprove the feasibility of the concept and missions. It is also noted that at this time all possible future demonstrations of beamed energy and power transfer will be pursued solely by NASA.

Download or read book Investigation of Beamed Energy Concepts for Propulsion. Systems Studies written by M. Huberman and published by . This book was released on 1976 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program is to assess the feasibility of the beamed energy propulsion concept for Air Force missions. The results of the study indicate that beamed energy propulsion is technically feasible. No fundamental obstacles have been identified. However considerable technical development is needed in many areas before the concept can be operationally implemented. In order to minimize the required collector area, laser concepts are preferred over microwaves. If space based laser transmitter concepts are to be cost effective they will require the availability of megawatt level space nuclear or solar power stations. In view of the large total energy required for each mission, ground based transmitters will be most cost effective when they are operated closed cycle from central station electric power. Laser transmitting ranges greater than several hundred nautical miles will result in excessive collector sizes. Therefore, ground based transmitters applications will be restricted to orbital functions which can be performed at low orbital altitudes. Three promising applications have been identified. The laser powered tug can be cost effective compared to an advanced cryogenic tug. Apsidal rotation correction and drag make-up are two other missions where significant advantages may be realized for the laser powered concept.

Book Synopsis Advanced Energy Conversion Concept for Beamed-Energy Propulsion by : Leik N. Myrabo
Download or read book Advanced Energy Conversion Concept for Beamed-Energy Propulsion written by Leik N. Myrabo and published by . This book was released on 1987 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal objective of this study was to perform basic research investigations into an innovative power conversion concept for trans atmospheric, beamed energy propulsion: a new class of External Surface Impulse (ESI) thrusters. This advanced thruster principle could be used for atmospheric VTOL, high acceleration, and lateral flight (e.g., short-term cruise) propulsion of Single-Stage-To-Orbit (SSTO) beam-powered shuttlecraft of the next century. Three classes of ESI thrusters were initially examined: 1) simple thermal, 2) electrostatic and 3) electromagnetic. Beam power wavelengths from 10cm (microwave) to 0.3um (laser) were considered. The subsequent research effort concentrated on the simple thermal repetitively-pulsed ESI thrusters, energized with laser power and using air as the working fluid. Laser frequencies were selected because of the relative wealth of experimental data and theoretical research on laser impulse coupling which exists in the literature. The first year analytical effort has proven conclusively that such an engine can deliver high levels of thrust-to-beam-power at liftoff (e.g., at least an order-of-magnitude greater than beam-powered hydrogen-fueled rockets), with infinite specific impulse (decreased only, perhaps, by ablation of the thruster surface). Later along an orbital trajectory, the primary propulsion function would transition to other modes; upon leaving the atmosphere, the SSTO vehicle would continue in a pure rocket mode with a specific impulse (I sp) of 1000 seconds or more. Keywords: Advanced airbreathing propulsion, Beamed energy propulsion, External radiation heated (EH) thruster.

This book was released on 2019-01-16 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study to determine the feasibility of employing beamed electromagnetic energy for vehicle propulsion within and outside the Earth's atmosphere was co-funded by NASA and the Defense Advanced Research Projects Agency that began in June 2010 and culminated in a Summary Presentation in April 2011. A detailed report entitled "Beamed-Energy Propulsion (BEP) Study" appeared in February 2012 as NASA/TM-2012-217014. Of the very many nuances of this subject that were addressed in this report, the effects of transferring the required high energy-density electromagnetic fields through the atmosphere were discussed. However, due to the limitations of the length of the report, only a summary of the results of the detailed analyses were able to be included. It is the intent of the present work to make available the complete analytical modeling work that was done for the BEP project with regard to electromagnetic wave propagation issues. In particular, the present technical memorandum contains two documents that were prepared in 2011. The first one, entitled "Effects of Beaming Energy Through the Atmosphere" contains an overview of the analysis of the nonlinear problem inherent with the transfer of large amounts of energy through the atmosphere that gives rise to thermally-induced changes in the refractive index; application is then made to specific beamed propulsion scenarios. A brief portion of this report appeared as Appendix G of the 2012 Technical Memorandum. The second report, entitled "An Analytical Assessment of the Thermal Blooming Effects on the Propagation of Optical and Millimeter- Wave Focused Beam Waves For Power Beaming Applications" was written in October 2010 (not previously published), provides a more detailed treatment of the propagation problem and its effect on the overall characteristics of the beam such as its deflection as well as its radius. Comparisons are then made for power beaming using the disparate electromagnetic wavel
