Available in PDF, EPUB and Kindle. Book excerpt: The Propulsion Research Center at the University of Alabama Huntsville has developed a liquid oxygen propellant feed system that has advanced into operational maturity. In support of safe system functional development, an oxygen compatibility and hazards assessment was completed in order to identify and minimize operational risks. The objective of this effort was to minimize potential risks that might have been overlooked in the initial design phase or resulted from a discontinuity between design and fabrication. The effort involved an internal review of the operating procedures and the system configuration, as well as an overall review by an oxygen safety engineering consultant. This paper outlines the review procedures applied to the oxygen propellant systems, summarizes the significant findings, and details configuration changes made to the system. The review process identified several areas in which reliance on procedural control, without compromising safe system operation, could be reduced or removed through design changes. Such changes were implemented so as to create a more fault tolerant system and minimize risks to test equipment, system hardware, and test personnel. Major upgrades included initiatives to manage the oxygen risk and mitigate specific oxygen ignition mechanisms. Oxygen compatible materials and facility configuration changes enabled safer experimentation in the demonstration testing of the cryogenic propellant facility. The findings presented in this paper represent the system changes made in an effort to increase safety and decrease the risk of fire in order to achieve a low probability of ignition and a low consequence of ignition.

Book excerpt: The Air Force Research Laboratory (AFRL), in order to support the Evolved Expendable Launch Vehicle (EELV) Program, recently activated a large liquid rocket engine test stand after a 25 years dormancy. Test Stand 1A, located at Edwards AFB CA, was left in a semi-abandoned condition since the early 1970's. With no definitive plans for re-activation, the facility was left to weather in the dry desert air. The objective was to provide the Air Force with the capability to test large liquid rocket engines up to 1.6 million pounds of thrust which utilize liquid oxygen for the oxidizer and either liquid hydrogen or kerosene for fuel. A high pressure hydrogen turbopump spin capability was also added to enable turbopump component development testing. This paper will review the lessons learned and observations from designing, modifying, and activating the test stand and performing the initial development activity on the new RS-68 rocket engine being developed for the Boeing Delta IV launch vehicle.

This book was released on 1991 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the advanced and final development phases of rocket engine component and subsystem testing failures are very likely to occur from time to time. To minimize or prevent damage or destruction to the components and to the test facility itself, high pressure oxygen supplied must be cut off rapidly on the order of 100 to 400 milliseconds. However, rapid cutoff of liquid oxygen, as well as, other liquids and high pressure gases can impart large pressure surges and hammer forces. For liquid and gaseous oxygen this phenomenon can initiate ignition and subsequent destruction of test articles as well as facility piping systems.

Book excerpt: The necessity for experimental verification of rocket-engine performance at altitude or near-space conditions has long been recognized in the aerospace industry. Recent spacecraft rocket-engine research and development trends toward higher area ratios, advanced nozzle concepts, and nonequilibrium flow conside ations have made altitude simulation a requirement of development pro- grams. Recause the need for information regarding the capabilities and char- acteristics of altitude test facilities that are suitable for l%id-rocket%- engine operation was recognized, this survey was compiled with the help of representatives of industry and government agencies;% % INTROPUCTION The advent of upper-stage and spacecraft engine-vehicle development pro- grams along with the need for more rigorous performance and reliability data justified the construction of a number of altitude test facilities. The test capabilities of these facilities range from small attitude-control engines to large upper-stage engines. The altitude-simulating systems include simple diffusers coupled to the engine nozzle exit (fig. 1), steam ejector coupled to the engine-driven diffuser (fig. 2), and pumped environmental chambers coupled to a diffuser or ejector system for use during engine firing (fig. 3). Several techniques for vacuum generation exist. In addition to the conventional sys- tems of mechanical pumps and steam boilers for stem% ejectors, there are semi- portable liquid-propellant-driven steam generators.

Available in PDF, EPUB and Kindle. Book excerpt: The 1959 Cryogenic Engineering Conference Committee is pleased to pre sent the papers of the 1959 Cryogenic Engineering Conference. We are fortunate to have had the University of California at Berkeley, Ca!., as our host for the fifth national meeting of this kind. The move to the West Coast for this past Cryogenic Engineering Conference was prompted in part by the large concentration of missile activities which are to be found there. Recognition of cryogenic operations and techniques in the mis sile field is given in many of the included papers. The University of California was certainly wen suited for such a meeting as this because it was here that much early work was done in cryogenics. This pioneering in cryogenics is still evident today in the operation of the 72-in. bub ble chamber at the Lawrence Radiation Laboratory. The Cryogenic Engineering Conference salutes the missile industry and the cryogenic pioneers of yesterday and today at the University of California. Special thanks must go to Dr. D. N. Lyon from the Low-Temperature Laboratory of the University of California, who as chairman of the 1959 Cryogenic Engineering Conference Committee has worked tirelessly to increase the stature of this conference. vii ACKNOWLEDGMENT The Cryogenic Engineering Conference Committee is deeply grateful for the continued support and interest of the following organizations who made the 1959 Cryogenic Engineering Conference possible.

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.

This book was released on 2018-07-10 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report covers the work done in preparation for a liquid oxygen rocket engine turbopump test utilizing high pressure hot oxygen gas for the turbine drive. The turbopump (TPA) is designed to operate with 400 F oxygen turbine drive gas. The goal of this test program was to demonstrate the successful operation of the TPA under simulated engine conditions including the hot oxygen turbine drive. This testing follows a highly successful series of tests pumping liquid oxygen with gaseous nitrogen as the turbine drive gas. That testing included starting of the TPA with no assist to the hydrostatic bearing. The bearing start entailed a rubbing start until the pump generated enough pressure to support the bearing. The articulating, self-centering hydrostatic bearing exhibited no bearing load or stability problems. The TPA was refurbished for the hot gas drive tests and facility work was begun, but unfortunately funding cuts prohibited the actual testing. Urke, Robert L. Unspecified Center...
