摘要:
A multi-engine aircraft (20) includes first and second gas turbine engines (10', 10") for providing motive power to the aircraft, each of the first and second engines (10', 10") comprising an air system (27, 29), an air pressure line (26) extending between and fluidly connecting the air systems (27, 29) of the first and second engines (10', 10"), and a pressure wave damper (31) communicating with the air pressure line (26) extending between the first and second engines (27, 29).
摘要:
A steam turbine (1) includes a rotor shaft (21) which includes disk portions (23) which extend from a shaft core portion (22) rotating about an axis (Ar) toward a radially outer side (Dro) and a plurality of rotor blades (32) which are disposed in a circumferential direction (Dc) of the shaft core portion (22). A first surface (100) which is toward a first direction including a directional component toward a radially inner side (Dri) is formed on each of the rotor blades (32). A second surface (200) facing the first surface (100) is formed on each of the disk portions (23). Balance hole portions (40A) which are recessed to communicate with each other in an axial direction (Da) are formed in at least one of the first surface (100) and the second surface (200).
摘要:
A system is provided for cross engine coordination during gas turbine engine motoring. The system includes a first gas turbine engine (10A) of a first engine system (100A), a first air turbine starter (120A) of the first engine system (100A), a first starter air valve (116A) of the first engine system (100A), and a controller (102A). The controller (102A) is operable to command the first starter air valve (116A) to control delivery of compressed air to the first air turbine starter (120A) during motoring of the first gas turbine engine (10A), monitor cross engine data of a second gas turbine engine (10B) of a second engine system (100B) to detect a present condition or a commanded action that modifies an aspect of the compressed air received at the first starter air valve (116A), and command an adjustment to the first engine system (100A) to compensate for the modified aspect of the compressed air based on the cross engine data.
摘要:
An apparatus includes a thermoelectric (TE) device (82), a gas flow conduit (80) proximate to one side of the thermoelectric device, a plurality of flexible tubes (84) proximate to a second side of the thermoelectric device, and a spring (86) to control contact force between the flexible tubes and the thermoelectric device. The spring comprises a coil spring at least partially circumscribing the gas flow conduit. The thermoelectric device converts a temperature differential between the flexible tubes and the gas flow conduit into electrical energy.

Die Erfindung betrifft einen Turbomaschinenstrang mit einem einen Stator (9) aufweisenden Generator (6), einem ersten Teilstrang (2), der sich ausgehend von dem Generator (6) in die eine Axialrichtung des Turbomaschinenstrangs (1, 12) erstreckt und der eine erste Strömungsmaschine (4) sowie einen radial innerhalb des Stators (9) angeordneten Innenläufer (7) aufweist, und einem zweiten Teilstrang (3), der sich ausgehend von dem Generator (6) in die andere Axialrichtung des Turbomaschinenstrangs (1, 12) erstreckt und eine zweite Strömungsmaschine (5) sowie einen radial außerhalb des Stators (9) angeordneten Außenläufer (8) aufweist, wobei der Innenläufer (7) eine Innenerregerwicklung zum Erzeugen eines Innenmagnetfelds und der Außenläufer (8) eine Außenerregerwicklung zum Erzeugen eines Außenmagnetfelds aufweist, so dass durch Einschalten des jeweiligen Magnetfelds jeder der Teilstränge (2, 3) mit dem Generator (6) einzeln kuppelbar und durch Ausschalten des jeweiligen Magnetfelds jeder der Teilstränge (2, 3) von dem Generator (6) einzeln entkuppelbar ist.
摘要:
A power generation system 100 includes: a first gas turbine system 102 including a first turbine component, a first integral compressor 106 and a first combustor 108 to which air from the first integral compressor and fuel are supplied, the first combustor 108 arranged to supply hot combustion gases to the first turbine component, and the first integral compressor having a flow capacity greater than an intake capacity of the first combustor and/or the first gas turbine component, creating an excess air flow. A second gas turbine system 140 may include similar components to the first except but without excess capacity in its compressor. A control valve system 202 controls flow of the excess air flow from the first gas turbine system 102 to the second gas turbine system 140. A heat exchanger 252 may be coupled to the excess air flow path for exchanging heat with the excess air flow.
摘要:
A drive architecture comprises a rotor (20) and a gearbox (22) for driving the rotor (20). A pair of input gears (26, 30) provides rotational drive to the gearbox (22). A first recuperative cycle engine (18) drives one of the pair of gears (26) and a second engine (19) drives the other of the pair of gears (30). The first recuperative cycle engine (18) and the second engine (19) are both gas turbine engines. A power takeoff (72) from a drive shaft (28) of the second engine (19) supplies rotational drive to drive at least one component (32) in the first recuperative cycle engine (18).
