Thermal management system with thrust recovery for a gas turbine engine fan nacelle assembly

A thermal management system locates a separate engine heat exchanger and generator heat exchanger into an engine nacelle pylon that is split to provide independent control of both a generator cooling circuit and an engine cooling circuit. A variable exhaust nozzle is provided downstream of each heat exchanger as each has different thermal and heat rejection requirements such that intake air is minimized and maximum thrust is produced in response to the current generator load and engine heat rejection.

Pressure exchanger

A pressure vessel provided with a first port acting as a high pressure inlet of a first stream and a second port acting as a high pressure outlet. A rotatable valve element is located in the centre of the machine and includes a centre plate, which is utilized to separate high pressure streams. At each end of the valve element are valves. The valves ensure that as the valve element rotates the exchange ducts are either both isolated or that one is exposed to high pressure while the other is exposed to low pressure. In operation, a fluid stream is introduced to the machine at high pressure through port and flows around the outside of the exchange duct towards the centre of the machine. The stream then flows downwardly to the valve element, where it then passes through the open ports of the valve element and into flow distributor. The stream then passes into and upwardly in the exchange duct, causing upward displacement of the duct piston, resulting in the pressurization and flow of the second fluid above the duct piston. The second fluid then flows into the upper flow distributor, into the valve element, and then downwardly and finally between the exchange duct and out through the high pressure port. At the same time a fluid stream is introduced to the machine at low pressure through port. This flows into the valve element and then into the flow distributor. From the flow distributor it flows and downwardly into the pressure exchange duct, causing downward displacement of duct piston and resulting in flow of the first fluid below the duct piston, which then flows into the lower flow distributor, into the valve element, and then out of the lower sealing plate at port. A planar radial sealing surface promotes sealing connection between the rotatable valve element and various pressure exchange ducts within the pressure vessel.

Meander line antenna coupler and shielded meander line

InactiveUS20050225496A1Less ohmic lossEliminates down firingResonant long antennasRadiating elements structural formsResonanceEngineering
A switched meander line structure is substituted for a lumped element coupler (10) for an order of magnitude increase in gain due to the use of the switched meander line architecture. The use of the meander line (20) with relatively wide and thick folded legs markedly decreases I2R losses over wire inductors whose wire diameters at one-tenth of an inch contribute significantly to I2R losses. Additionally, placing solid state switches to short out various sections of a multi-leg meander line at high impedance nodes reduces I2R losses across the switching elements in the coupler. It has been found that, regardless of the impedance of the antenna, this impedance may be matched by switching in and out various sections of a folded multileg meander line due to the fact that the square of the sum of the capacitive reactances of the meander line decreases with frequency in synchronism with the unloaded Q of the meander line, thus to provide the ability to maintain a good match over frequency as the meander line is tuned to achieve resonance by shorting out combinations of sections of the meander line. The result of the substitution of the meander line architecture for the lumped element coupler is the reduction of losses associated with the use of wire inductors and losses due to the interposition of solid state switches at high-current nodes.

A system for irradiating material used in transfusions. The material can be pre-transfused blood, blood components and marrow. The system includes a vacuum chamber with a plate cathode inside. The cathode has a large beam electrode field-electron emissive surface with a selected cross-sectional shaped area. A power supply is connected to the cathode for generating negative high-voltage pulses and causing a selected cross-sectional shaped beam of electrons to be emitted. An electron window is also disposed inside the vacuum chamber and made of thin metal foil. The electron window receives the selected cross-sectional shaped beam of electrons therethrough and onto an electron target disposed outside the vacuum chamber. The electron target receives the selected cross-sectional shaped beam of electrons thereon and generates a selected cross-sectional shaped X-ray beam. A cathode filter is disposed next to the electron target and eliminates low energy beams from the spectrum of the X-ray beam. The filtered X-ray beam exposes the material to high energy beams for irradiation.

Method of super super decoupled loadflow computation for electrical power system

A method of performing loadflow calculations for controlling voltages and power flow in a power network by reading on-line data of given / specified / scheduled / set network variables / parameters and using control means, so that no component of the power network is overloaded as well as there is no over / under voltage at any nodes in the network following a small or large disturbances. The invented generalized Super Super Decoupled Loadflow (SSDL) calculation method is characterized in that 1) modified real power mismatch at any PQ-node-p is calculated as RPp=[ΔPp′+(Gpp′ / Bpp′)ΔQp′] / Vp2, which takes different form for different manifestation of the generalized version SSDL-X′X′ method, 2) transformed values of known / given / specified / scheduled / set quantities in the diagonal elements of the gain matrix [YV] of the Q-V sub-problem are present, and 3) transformation angles are restricted to maximum of −48° particularly for the most successful version SSDL-YY method, and these inventive loadflow calculation steps together yield some processing acceleration and consequent efficiency gains, and are each individually inventive. The other two Super Super Decoupled Loadflow methods: BGX′ version (SSDL-BGX′) and X′GpvX′ version (SSDL-X′GpvX′) are characterized in the use of simultaneous (1V, 1θ) iteration scheme thereby calculating mismatches only once in each iteration and consequent efficiency gain.

The coronagraph apparatus comprises in sequence from left to right: an outer shielding body, an outer window, a heat collecting lens, an inner shielding body, an inner shielding body light-absorbing groove, an imaging system and a CCD camera. The outer shielding body and the inner shielding body are disposed on the optical axis of an optical path. The inner shielding body is positioned in an imaging position where the outer shielding body passes through an object lens unit. The coronagraph apparatus, as a whole, is of a semi-open square structure, and is reduced in size and weight. The heat collecting lens is a reflector with a square centrally-recessed structure, and the recessed surface of the centrally-recessed structure faces one side of the outer window. The heat collecting lens is arranged in an inclined manner. The lower end of the heat collecting lens goes toward one side of the outer window relative to the upper end of the heat collecting lens. Incident sun direct light is focused by the heat collecting lens outside the semi-open square structure, so the influence of scattered stray light on the surface of the heat collecting lens is reduced.
