This book was released on 1971 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes the results of the O2/H2 Advanced Maneuvering Propulsion Technology Program Bell Engine study. The objective of the study was the definition of main rocket engine systems applicable to advanced cryogenic oxygen/hydrogen space vehicles. The study described in this volume was directed toward non-aerospike nozzle configurations to provide designs for comparison to the aerospike configuration described in Volume 1. Preliminary engine designs were prepared for thrust levels from 8,000 to 50,000 pounds for several nozzle and engine system configurations. A detailed design and analysis was carried out for a selected 25,000-pound-thrust engine configuration. The analysis included the effects of variations in certain engine system design conditions, development programs and costs, failure mode, effects, operational characteristics, and maintenance plans.

This book was released on 1971 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: The engine system design and analysis studies provide a detailed definition of two 25,000-pound-thrust O2/H2 aerospike engines. The single-panel aerospike engine design point corresponds to the demonstrator thrust chamber configuration, specifically, chamber pressure and area ratio equal to 750 psia and 110:1, respectively. A second engine system and component design and operational description also is provided for the selected optimum aerospike engine employing a double-panel thrust chamber cooling circuit. The double-panel aerospike engine design has a chamber pressure and area ratio of 1000 psia and 200:1, respectively. These engine systems are designed to provide 5:1 throttling and off-design mixture ratio operation. The study effort also included the effects of variations in certain design parameters on engine performance, weight, propellant flow balances, life capability, development time and cost, and maintenance requirements. Additional parametric information is provided for design thrust levels between 8000 and 50,000 pounds. (Author).

This book was released on 1972 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the analysis, design, fabrication, and test of water-cooled segments to define the most suitable injector configurations and combustion chamber geometries for 25,000-pound-thrust, O2/H2, lightweight, aerospike thrust chambers. Two-hundred and seventy-one hot-fire tests with numerous injector and chamber configurations were conducted at chamber pressures between 140 and 988 psi. The injector development was supplemented with cold-flow tests of single injection elements. High measured performance was demonstrated in low-volume combustion chambers (3.0-inch length from injector face to the throat).

Book excerpt: From the authors' abstract: "This analytical study looks at the importance of Deep Space Operations and recommends an approach for senior policy leaders. Section 1 presents a capability requirements definition with candidate solutions and technology strategies. Section 2 recommends an acquisition and organizational approach. Section 3 provides an extended strategic rationale for deep space operations as a national priority." And from the Introduction: [this essay] "presents capability requirements, potential solutions, and strategic rationale for achieving movement and maneuver advantage in deep space. In this context, deep space is anything beyond geosynchronous Earth orbit (GEO). Driving the research are two primary assumptions underpinning the need for investment in deep space propulsion. The first assumption is that growing international activity, commerce, and industry in space extends the global commons, thus creating a military-economic imperative for the United States Department of Defense (DoD) to expand its protection of U.S. interests by defending space lines of communication. Although there are wide-ranging reasons to expand the space-faring capabilities of the human species, from the capitalistic to the existential, the fact of its occurrence offers the U.S. immense strategic opportunity. Section 1, operating on this assumption, recommends capability-based requirements for deep space operations given a projected future operating environment.The second driving assumption underpinning this study is that improved movement and maneuver capabilities in deep space offer a wide array of benefits for the current National Security Enterprise, and for this reason alone demands attention in the form of disciplined investment. Furthermore, because the core functional capability required for deep space operations is in-space propulsion, the requirement necessitates a materiel solution.

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).

This book was released on 1966 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: The previous study results of Contract AF04(611)-10745 are extended to investigate the capabilities of increased gross weight Maneuvering Space Propulsion Systems (MSPS) using LF2/LH2, LO2/LH2, and N2O4/N2H4-UDMH(50-50) propellants. The range of stage gross weights considered was based on the payload capabilities of Titan III-C and Saturn I-B and several growth versions of these launch vehicles. Maneuvering space propulsion system gross weights ranging from 20,000 to 50,000 pounds were shown to result in velocity increment capabilities up to 29,000 ft/sec for the 2000-pound payload LF2/LH2 system. The concentric aerodynamic spike/bell engine configuration was selected for the LF2/LH2 and LO2/LH2 system design thrust levels investigated. The configuration selected for the N2O4/N2H4-UDMH(50-50) consisted of one larger primary bell nozzle engine and two small secondary bell nozzle engines. The orbit storage life capabilities of the three propellant combinations were determined and compared for a 20,000-pound-gross weight stage. The LF2/LH2 system provided higher delta V capabilities than the other propellants for orbital storage times up to 2 years with full propellant tanks. The delta V advantage for the LF2/LH2 systems is also maintained when mission duty cycles result in partial propellant loads for the major portion of the storage duration. (Author).
