Abstract:
Preparation of sintering resistant hexaaluminates, AAl11O18, wherein A is an alka-line earth or rare earth metal, and more particularly lanthanum, by a combination of sol-gel and microemulsion techniques using a water soluble salt of A, and a method of forming spherical pellets thereof are disclosed.
Abstract:
The present invention relates to a reactor for the decomposition of ammonium dinitramide-based liquid monopropellants into hot, combustible gases for combustion in a combustion chamber, and more particularly a rocket engine or thruster comprising such reactor and a combustion chamber. The invention also relates to a process for the decompostion of ammonium dinitramide-based liquid monopropellants.
Abstract:
The present invention relates to a system comprising a hermetic centrifugal separator where the separator comprises a rotor including a separation chamber, an inlet channel for a mixture of components to be separated, a first outlet channel for receiving at least one separated light component, and a second outlet channel for receiving at least one separated heavy component.
Abstract:
A system includes a hermetic centrifugal separator, a recirculation system, a first monitoring system, a first control system, a pressure monitoring system, and a pressure control system. The separator includes a rotor, a separation chamber, an inlet channel for separating components, a first outlet channel for receiving separated light components, and a second outlet channel for receiving separated heavy components. The recirculation system recirculates the separated heavy components from the second outlet channel to the separation chamber. The first monitoring system monitors density and/or flow rate of the heavy components in the second outlet channel. The first control system controls flow rate in response to a control signal from the first monitoring system. The pressure monitoring system monitors pressure in the second outlet channel. The pressure control system controls a back pressure valve in the second outlet channel in response to a control signal from the pressure monitoring means.
