  • Publication number: 20160032867
    Abstract: A hybrid rocket engine is described that achieves stable, highly efficient hybrid combustion by having a core flow of fuel-rich gas generator gases, with the flow being surrounded with an annular injection of oxidizer. The fuel-rich gas serves to vaporize and decompose the oxidizer, such as nitrous oxide, and prepare it for effective, stable combustion. In one embodiment, this is done at the head-end of a combustion chamber. The combustion products can then be expanded through a nozzle to create thrust. The engine can be an upper stage engine that can include modular thrust chambers and an integrated aerospike nozzle. The thrust chambers can be arranged in an array that rings the top of the aerospike nozzle.

  • Patent number: 8051640
    Abstract: A solid propellant thrust control system, method, and apparatus for controlling combustion of solid propellants in an opposing grains solid propellant rocket engine (OGRE) is provided. In particular, an opposing grains rocket engine and propulsion system is provided, in which actuator means connected are connected to solid propellant grains disposed in the pressure vessel of the engine. The actuator means are operable to selectively move the solid propellant grains together or apart relative to one another, such that the burning ends of the solid propellant grains decrease or increase relative to one another. This action controls the rate of combustion of the solid propellant grains by varying spacing distance between the burning ends of the solid propellant grains, and enables extinguishment and reignition of the OGRE. Further, a method is providing for controlling the burn rate of solid propellant grains undergoing combustion in an opposing grains rocket engine.

  • Publication number: 20020032591
    Abstract: A virtual assistant system for information retrieval and management and service request processing includes a user interaction device (UID), a server computer, a system computer, and a human-controlled call center. The UID permits the user to provide voice or written instructions to the system computer via the server computer. The system computer runs artificial intelligence (AI) routines to process or preprocess commands provided into the UID by the user. When possible, the AI routines complete the requested service. Where the AI routines alone are insufficient, a human-controlled call center corrects and completes the service requests. Skilled human labor, then, is only relied upon when needed by the system. A great range of service requests can be made including, e.g.
