    Reducing energy storage requirements of space power systems by illuminating the photovoltaic arrays with a remotely located laser system is addressed. It is proposed that large lasers be located on cloud-free sites at one or more ground locations and that large lenses or mirrors with adaptive optical correction be used to reduce the beam spread due to diffraction or atmospheric turbulence. During ... View full abstract»

    Power requirements for an electric propulsion Earth orbital transport vehicle (EOTV), which can effectively deliver large payloads using much less propellant than chemical transfer methods, are addressed. The power beaming concept is described. Arcjets, magnetoplasmadynamic (MPD) thrusters, and ion engines are covered. Power supply characteristics are discussed for nuclear, solar and power-beaming...

    A 1984 survey of the nickel hydrogen (NiH/sub 2/) battery industry is updated. Late 1980s and early 1990s issues are identified, and usage and testing results of the survey are summarized. NiH/sub 2/ is the system of choice for new geosynchronous-earth-orbit (GEO) satellites and is being seriously considered for low-earth-orbit (LEO) applications. In five years, the annual cell production rate has... View full abstract»

    The application of magnetostriction in the design of a hybrid, electromechanical/hydraulic high-performance linear (large force and stroke) and/or rotational (large moment and angle) actuator is considered. The design concept combines the high power density of actuation possible with magnetostriction (approaching 0.1 HP/cm/sup 3/ of the magnetostrictive material assuming 3 kHz excitation frequency...
