    摘要： A system and methods are provided for combining systems of an upper stage space launch vehicle for enhancing the operation of the space vehicle. Hydrogen and oxygen already on board as propellant for the upper stage rockets is also used for other upper stage functions to include propellant tank pressurization, attitude control, vehicle settling, and electrical requirements. Specifically, gases from the propellant tanks, instead of being dumped overboard, are used as fuel and oxidizer to power an internal combustion engine that produces mechanical power for driving other elements including a starter/generator for generation of electrical current, mechanical power for fluid pumps, and other uses. The exhaust gas from the internal combustion engine is also used directly in one or more vehicle settling thrusters. Accumulators which store the waste ullage gases are pressurized and provide pressurization control for the propellant tanks. The system is constructed in a modular configuration in which two redundant integrated fluid modules may be mounted to the vehicle, each of the modules capable of supporting the upper stage functions.

    摘要： The process of the present application facilitates the production of electric energy for spacecraft by the seizure of beta-minus particles and electrons present in the medium of space above and beyond the planet's atmosphere. The features of the subject process make each spacecraft independent from domestic energy sources as are typically required by other electrical systems. In terms of energy production, the subject process will outperform all of the traditional systems applied to spacecraft including photovoltaic setups, fuel cells, batteries and nuclear systems. Photovoltaic panels situated in space are quickly degraded by bombarding cosmic ray particles and solar wind emissions. Since fuel cells require very high operating temperatures, it exposes the craft, its instrumentation and occupants to constant danger. By utilizing the process of the present application, it is no longer necessary for spacecraft to carry large quantities of chemicals for batteries, fuels and oxidizers for fuel cell generators, hazardous nuclear generators or large bulky photovoltaic panels subject to frequent malfunction. It is an innovative process for the production of electric energy by the attraction and seizure of beta-minus particles and electrons emitted from the Sun's corona as part of the solar wind that permeates the heliosphere. Because it captures free electrons directly, it does not consume power to convert one form of energy into another. It functions continuously throughout and beyond the heliosphere. It can be scaled to accommodate the electric power requirements of all spacecraft, including satellites and space stations. The process will accommodate the electric needs of base stations and surface vehicles situated on various moons and asteroids throughout the solar system including the planets Mercury and Mars. Some of the terms that describe the advantages of the process of the present application are simplicity, efficiency, adaptability, versatility, low energy consumption, and high productivity. Consequently, a reliable, enduring and safe electric power source for space craft has not been available until the development of the process of the present application.

    摘要： Methods and apparatuses for augmenting thrusts using ionized gases. A gas is partially ionized, which then ionizes a second, neutral gas. Vector addition can be used to increase the velocity of the first ionized gas with relatively high efficiency due to the gyroradii of the ionized particles. If the velocity is sufficiently high the critical ionization velocity of at least some of the elements in the second gas will be exceeded, greatly increasing A magnetic field creates a Townsend cascade in the ionized gases, greatly increasing the amount of ionized gases. The magnetic field can be created using permanent magnets or superconductors, thereby requiring little or no power to operate. To produce thrust the ionized gases are accelerated through a coil, which can have logarithmically increasing coil spacings. Electrical power can be generated by passing the accelerated ionized gas through generating coils and/or a turbine. In another embodiment, electromagnetic forces in the atmosphere can be used to propel a vehicle that has parallel superconducting coils circumferentially disposed about an axis of travel of the vehicle, the coils comprising one or more moveable segments which are reversibly disconnectable from other segments in said coil, thereby allowing the polarity of the coil to be reversed. The ionization engines described above can be used to further accelerate or decelerate the vehicle.

    摘要： An energy conversion system is provided for converting thermal radiation energy into electricity. The system includes a source of thermal energy and a silicon cell spaced from the thermal energy source. A radiating solid material is positioned between and spaced from the thermal energy source and the silicon cell. The radiating solid material is capable of radiating a major portion of the heat received from the thermal energy source in the spectral band where the silicon cell shows its maximum spectral response. An interference filter is positioned between the radiating solid material and the silicon cell. The interference filter has its maximum reflectivity in the strongest emission band regions of the radiating solid material which are outside the maximum spectral response band of the silicon cell. The interference filter also has its highest transmission in the wavelength region where the silicon cell has good spectral response. This invention relates to an energy conversion system for converting thermal radiation energy to useful electrical energy.
