A pump has a brushless electrical motor including a stator assembly and a rotor ring arranged externally of the stator assembly. The pump further has a centrifugal impeller operatively connected to the rotor ring such that the electrical motor rotates the impeller. The impeller is configured to raise the pressure of a fluid which flows through the impeller between an inlet and an outlet thereof. The pump is configured such that a portion of the raised pressure fluid flow is diverted to form a recirculation flow which circulates through and cools the electrical motor before being returned to the impeller for re-pressurisation thereby.

A gas turbine engine (100) heat exchange system (200) includes a first microchannel heat exchanger (MCHX) (108, 118, 300) configured to transfer heat between a first air stream (114, 122, 208, 210, 322) and a working fluid (330). The first MCHX (108, 118, 300) includes a plurality of air-passage layers (328, 700). Each of the air-passage layers (328, 700) includes a plurality of etched air-passage microchannels (320, 702) that are configured to allow passage of the first air stream (114, 208, 322) therethrough. The first MCHX (108, 118, 300) may include a plurality of working fluid layers (324, 500). Each working fluid layer (324, 500) includes a plurality of etched working fluid microchannels (402) that are configured to allow passage of the working fluid (330) therethrough.

In order to make a drive device available on the basis of a gel-type propellant, in particular, for a flying object, comprising at least one tank for gel-type propellant, a combustion chamber and a device for supplying propellant to the combustion chamber, which is of a simple construction it is suggested that at least one radiation impinging device be provided for acting on gel-type propellant with electromagnetic radiation and/or at least one heating device for heating gel-type propellant in order to improve the flow behavior.
摘要:
In a rotary turbine having inlets for mixtures of gas and liquid, and a rotary shaft, the combination comprising a separator to receive the mixture of gas and liquid, and to separate the mixture into a stream of gas and a stream of liquid; first structure to receive the stream of gas for generating torque exerted on the shaft; the separator including a rotating surface to receive the stream of liquid to form a liquid layer, and for generating torque exerted on the shaft; there being generally radial outflow passages for the separated liquid stream, and liquid nozzles terminating liquid outflow passages to pass the liquid stream and to convert the induced pressures of the radial outflow of the liquid to velocity of liquid jets, and to convert the reaction forces of the liquid jets to shaft power. Gas nozzles may be provided to receive the separated gas stream which is centrifugally pressurized and expanded through the gas nozzles to produce gas jets directed to produce torque acting on the shaft.
