This book was released on 1981 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: An advanced development contract was conducted in support of the Air Force Ballistic Missile program to demonstrate a lightweight liquid-bipropellant feed system for application in an advanced post-boost propulsion system. The feed system is composed of composite-wrapped aluminum propellant storage tanks and a catalytically reacted warm-gas pressurization subsystem. Tank capability was demonstrated in workhorse expulsion characterization tests (expulsion efficiency of 98.1 to 99.3 percent) and fabrication and expulsion of a flight weight propulsion storage assembly (PSA). The latter was accomplished with a representative pressurization subsystem consisting of a composite-wrapped aluminum pressurant tank with Tridyne pressurant (helium, oxygen, and hydrogen), an electronically controlled pressure regulator, a catalytic reactor, and valves. The reactor supplied warm-gas pressurant to the PSAs at up to 1158 F. The delivered propellant pressure was controlled to 300 + or - 4 psia during pulsed propellant flow by continuous modulation of the pressurant flow. The feed system was sized to deliver 1400 pounds of N2O4 and MMH with each PSA weighing 59 pounds, and the PS weighing 41 pounds. The resultant weight savings was 27 to 35 percent when compared to more conventional systems. (Author).

This book was released on 1996-01-22 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key to opening the use of space to private enterprise and to broader public uses lies in reducing the cost of the transportation to space. More routine, affordable access to space will entail aircraft-like quick turnaround and reliable operations. Currently, the space Shuttle is the only reusable launch vehicle, and even parts of it are expendable while other parts require frequent and extensive refurbishment. NASA's highest priority new activity, the Reusable Launch Vehicle program, is directed toward developing technologies to enable a new generation of space launchers, perhaps but not necessarily with single stage to orbit capability. This book assesses whether the technology development, test and analysis programs in propulsion and materials-related technologies are properly constituted to provide the information required to support a December 1996 decision to build the X-33, a technology demonstrator vehicle; and suggest, as appropriate, necessary changes in these programs to ensure that they will support vehicle feasibility goals.

Available in PDF, EPUB and Kindle. Book excerpt: The Demonstration of Advanced Post-Boost Propulsion Subsystems had as its objective the development of improved technology for advanced, post-boost liquid propulsion subsystems having a ten-year storage life and which would be maintenance-free, inherently reliable, and offer minimal production costs. The effort was devoted to providing technological improvements in the primary subsystems selected which would permit their ready incorporation into an Advanced Post-Boost Propulsion System for the next generation of ICBM weapon systems. The Aerojet-General Corporation utilized specialized subcontractor experience for the development effort associated with three of the primary subsystems. The Hamilton Standard Division of United Aircraft development activity concerned a staged, monopropellant gas generator for pressurization. Arde, Inc. was responsible for the propellant tanks and positive expulsion. They utilized all-welded steel conospheroid tanks with wire-reinforced, controlled collapse, steel diaphragms. Aerojet-General accomplished the necessary engine development which was limited to workhorse hardware solely intended for use in testing the controls subsystem components. Development culminated in gas pressurization and propellant tank/expulsion subsystem demonstrations that indicate these subsystems are ready for final weapon system development as well as application. In connection with the fluidic controls components, the feasibility of the concept was demonstrated; however, further basic component technology research will be required for any selected application.

Available in PDF, EPUB and Kindle. Book excerpt: On June 15, 2011, the Air Force Space Command established a new vision, mission, and set of goals to ensure continued U.S. dominance in space and cyberspace mission areas. Subsequently, and in coordination with the Air Force Research Laboratory, the Space and Missile Systems Center, and the 14th and 24th Air Forces, the Air Force Space Command identified four long-term science and technology (S&T) challenges critical to meeting these goals. One of these challenges is to provide full-spectrum launch capability at dramatically lower cost, and a reusable booster system (RBS) has been proposed as an approach to meet this challenge. The Air Force Space Command asked the Aeronautics and Space Engineering Board of the National Research Council to conduct an independent review and assessment of the RBS concept prior to considering a continuation of RBS-related activities within the Air Force Research Laboratory portfolio and before initiating a more extensive RBS development program. The committee for the Reusable Booster System: Review and Assessment was formed in response to that request and charged with reviewing and assessing the criteria and assumptions used in the current RBS plans, the cost model methodologies used to fame [frame?] the RBS business case, and the technical maturity and development plans of key elements critical to RBS implementation. The committee consisted of experts not connected with current RBS activities who have significant expertise in launch vehicle design and operation, research and technology development and implementation, space system operations, and cost analysis. The committee solicited and received input on the Air Force launch requirements, the baseline RBS concept, cost models and assessment, and technology readiness. The committee also received input from industry associated with RBS concept, industry independent of the RBS concept, and propulsion system providers which is summarized in Reusable Booster System: Review and Assessment.

Available in PDF, EPUB and Kindle. Book excerpt: The increased size and extended mission duty cycles of planned Post-Boost Propulsion Systems (PBPS) for Advanced ICBM applications identified the need for improvements in liquid propellant propulsion technology. Although liquid propellant propulsion systems have demonstrated an operational flexibility and performance capability, improvements in the inherent storability, maintainability, and reliability were desired for an optimum strategic weapon system. The PBPS Engine Development Program was initiated to develop a bipropellant N2O4 and MMH attitude control system (ACS) wherein integral fluidic controls are used to perform ACS propellant flow control, thereby controlling vehicle attitude with a minimum of moving parts. Developmental problems with the fluidic control elements resulted in the termination of the integral fluidic ACS development and the associated minimum ACS engine studies. The program was redirected to provide the development of a conventionally-controlled 75 lb thrust attitude control engine as well as the demonstration testing of PBPS pressurization and positive expulsion propellant tank subsystems. An Aerojet-General proprietary injector concept in conjunction with a bimetallic, conductively-cooled combustion chamber was used in the ACS engine developed. This engine was demonstrated in altitude performance and pulse testing. The monopropellant hot gas pressurization subsystem was used to demonstrate propellant expulsion (both monomethylhydrazine and N2O4) from the full-size ring-stabilized expulsion propellant tanks.

Available in PDF, EPUB and Kindle. Book excerpt: Automobiles are responsible for a substantial part of the world's consumption of primary energy, mostly fossil liquid hydrocarbons. The reduction of the fuel consumption of these vehicles has become a top priority. Many ideas to reach that objective have been presented. In most cases these systems are more complex than the traditional approaches. For such complex systems a heuristic design approach fails. The only way to deal with this situation is to employ model-based methods. This text provides an introduction to the mathematical modeling and subsequent optimization of vehicle propulsion systems and their supervisory control algorithms.

Available in PDF, EPUB and Kindle. Book excerpt: The Research and Development of Advanced Propulsion Systems Study was directed toward the development of a method for defining the desirable characteristics of booster systems in the 1million to 20-million pound thrust regime. An investigation into the means of reducing costs of a booster system was made by the adoption of a design philosophy that places primary emphasis on low costs, and the secondary emphasis on performance. Final conclusions of the study are: LO2/LH2 are the best propellants to minimize system dollars per pound of payload in orbit; A building-block booster system will minimize total dollars per pound of payload in orbit; Aluminum semimonocoque construction now shows the least dollars per pound payload in orbit; The plug engine will allow a minimum dollars per pound of payload in orbit system; The development of a LO2/LH2 engine in the 1.5million to 3.5-million-pound-thrust class is required (the discrete size selected depends on a more precise definition and agreement of the missions and payloads); and A go-ahead on an engine and launch vehicle system development of the type studied, added to presently planned cryogenic utilization, will require expansion of liquid-hydrogen manufacturing facilities.

This book was released on 1970 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high performance LF2/LH2 maneuvering propulsion system has been defined, which provides an in orbit delta V capability in excess of 21,000 ft/sec with a 2000 pound payload. The system, which is designed for launch into a 100 nautical mile polar orbit with the Titan IIID, weighs 18,000 pounds fully loaded, has instant response and multi-start capability, while providing a nominal space residence duration of 14 days. Longer orbital stay times (up to 180 days) can be accommodated with some design modification without significantly degrading performance. This design can be used as the basis of a ground test article to demonstrate the feasibility of technical concepts applicable to a wide range of high performance stage sizes. (Author).
