Multi-mission Ni-H2 battery cells for the 1990's

A sufficient production, test and operational database is now available to permit design technology optimization for the next decade. The evolved battery cell design features standardized technology intended to support multiple type missions (e.g., both GEO and LEO). Design analysis and validation test cells demonstrate that improved performance plus attractive specific-energy characteristics will be achieved

Development of Sintered Fiber Nickel Electrodes for Aerospace Batteries

The nickel electrode is the specific energy limiting component in nickel battery systems. A concerted effort is currently underway to improve NiH2 performance while decreasing system cost. Increased performance with electrode specific energy (mAh/g) is the major goal of this effort. However, cost reduction is also an important part of the overall program, achieved by reducing the electrode weight. A lightweight, high energy density, nickel electrode is being, developed based on a highly porous, sintered fiber, nickel substrate. This developing technology has many applications, but is highly, applicable to the military and aerospace industries

From Earth to Orbit: An assessment of transportation options

The report assesses the requirements, benefits, technological feasibility, and roles of Earth-to-Orbit transportation systems and options that could be developed in support of future national space programs. Transportation requirements, including those for Mission-to-Planet Earth, Space Station Freedom assembly and operation, human exploration of space, space science missions, and other major civil space missions are examined. These requirements are compared with existing, planned, and potential launch capabilities, including expendable launch vehicles (ELV's), the Space Shuttle, the National Launch System (NLS), and new launch options. In addition, the report examines propulsion systems in the context of various launch vehicles. These include the Advanced Solid Rocket Motor (ASRM), the Redesigned Solid Rocket Motor (RSRM), the Solid Rocket Motor Upgrade (SRMU), the Space Shuttle Main Engine (SSME), the Space Transportation Main Engine (STME), existing expendable launch vehicle engines, and liquid-oxygen/hydrocarbon engines. Consideration is given to systems that have been proposed to accomplish the national interests in relatively cost effective ways, with the recognition that safety and reliability contribute to cost-effectiveness. Related resources, including technology, propulsion test facilities, and manufacturing capabilities are also discussed
