  • Patent number: 10124916
    Abstract: This invention serves as the fundamental design for a space-based, nuclear-powered spacecraft for deep space journeys. Nuclear energy is used as the motive power for the propulsion. The spacecraft propellant is a gas (such as helium or hydrogen), which is also the coolant for the onboard nuclear reactor. Nuclear energy is converted to thermal energy in the reactor, which heats up the propellant gas. That superheated gas then expands through the spacecraft nozzle and creates the thrust. The nuclear fuel consists of high enriched uranium. The amount of fuel is mission dependent, and requires declaration of payload, and desired speed, which is limited to sub-light for the first generation of this invention. The spacecraft will be assembled in, and launched from low earth orbit. The spacecraft final assembly consists of modular components delivered to low earth orbit from earth by conventional chemical rockets.

  • Patent number: 10088239
    Abstract: A heat exchanger has a first flow path communicating fluid into a turning flow path at a first mitered interface. The turning flow path has a second mitered interface for communicating fluid from the turning flow path into a return flow path. The first flow path extends in a nominal direction toward the turning flow path. First flow passages within the first flow path and return flow passages in the return flow path are provided by walls having alternating sections which extend in opposed angular directions relative to nominal directions. Sizes of a portion of passages at the interfaces are different such that some passages are larger than other openings into other passages.

  • Patent number: 9989317
    Abstract: In a heat exchanger, an outside air passage, through which outside air flows, is provided between adjacent tubes of the refrigerant tube and the coolant tubes. Disposed in the outside air passage is an outer fin joined to at least one of the refrigerant tube and the coolant tube and configured to accelerate heat transfer between the fluids. A dimension of the refrigerant tube in a flow direction of the outside air is different from a dimension of the coolant tube in the flow direction of the outside air. Hence, with respect to the outer fin joined to both of the refrigerant tube and the coolant tube, an area of a joint surface between the refrigerant tube and the outer fin is different from an area of a joint surface between the coolant tube and the outer fin.
