摘要： In a device for damping blade vibrations of an axial-flow turbomachine, the ends of the rotating blades form a seal toward the flow-limiting wall of a turbine casing. A ring of permanently magnetic material is attached to this flow-limiting wall of the turbine casing in the radial direction opposite the blade ends, which ring consists of at least one or more sectional rings of the same or different magnetic polarization. The blade ends are each provided with a cover plate which is made of a material which is a good electrical conductor.

摘要： A turbine device and a method of driving the turbine device are disclosed. The turbine device includes an admission channel, a turbine, and an injection channel. The turbine device may also include a regulator. The turbine is driven by injecting a primary fluid into the admission channel at a given velocity and simultaneously causing a secondary fluid to flow into the admission channel at a lower velocity. The primary fluid and the secondary fluid form a mixture in the admission channel, which flows toward the turbine. The velocity of the mixture is less than that of the primary fluid, while the mass flow of the mixture is approximately equal to the sum of the mass flows of the primary and secondary fluids. The regulator compares the rotational speed of the turbine to a target speed and regulates parameters associated with the turbine device if the rotational speed of the turbine and the target speed differ by more than a predetermined amount.

摘要： A self regulating bleed valve for a gas turbine engine is provided which taps or bleeds a portion of a gas, typically air, from a duct of the gas turbine having a wall bounding the gas flow. The bleed valve has a valve member pivotally attached to the wall such that the valve member extends through a main opening formed in the wall. The valve member has an internal cavity in communication with a gas inlet opening and a gas exhaust opening and is pivotally movable between an extended position wherein the gas inlet opening portion of the valve member extends into the gas flow duct such that the inlet opening faces generally in an upstream direction so as to deflect a portion of gas flow into the internal cavity, and a retracted position wherein the inlet opening extends obliquely, generally parallel, to the gas flow so as to minimize the air tapped or bled from the gas flow. The bleed valve also includes a control device fixedly attached to the valve member which is acted on by the flow of gas to cause the valve member to pivot between its extended and retracted positions, depending upon the speed and pressure of the gas flow. Thus, the self-regulating bleed valve taps or bleeds a generally constant amount of air regardless of the speed or pressure of the gas flow with which the valve is associated.

摘要： An air cycle machine (10) has a first stage turbine (60) mounted to a central portion of a common shaft (12), a compressor (50) mounted to the central portion of the shaft (12), a second stage turbine (30) mounted to a first end of the shaft (12), and a fan (40) mounted to a second end of the shaft (12), all for rotation therewith about a longitudinal axis (14). The first and second stage turbines (60, 30) are operative to extract energy from a flow of compressed air for driving the shaft (12), and the fan (40) and the compressor (50), in rotation about the axis (14). A bypass air discharge nozzle (20) is disposed coaxially with the turbine shroud (32) of the outboard turbine (30) at the outlet (134) thereof or downstream thereof at the discharge end (38) of the turbine diffuser (36) so as to receive in a central region the turbine exhaust (3 ) discharging from the turbine (30) and to define an annular flow inlet (28) through which a flow of bypass air (5) is directed into an outer circumferential region thereof to flow substantially parallel to and about the cooled expanded conditioning air exhaust flow (3) discharged from the turbine (30).

摘要： A hydraulic/pneumatic turbine transmission (10) for converting a pressurized fluid source (26) to rotary motion of variable torque and rpm is disclosed. Turbine transmission (10) generally has housing (12) including main body housing (12a) and front housing cover plate (12b). An output shaft (11) is rotatably secured within housing (12) and has a main turbine runner (16) radially attached thereto. Main turbine runner (16) includes a plurality of concentrically disposed subrunners of progressively smaller diameter. A pair of diametrically disposed variable position nozzles are provided and disposed within housing (12) to selectively supply pressurized fluid to any one of the plurality of subrunners. A plurality of arcuate scavenge ports (33) are provided within housing (12) to allow a pressurized fluid to exit subsequent to impact on main turbine runner (16). Variable position nozzles (23) can be independently controlled to produce 2x-1 output speeds, where x is equal to the number or subrunners.

摘要： A thermal performance monitor informs the operator and result's engineer of the economic losses, efficiencies, deviation in heat rates and power losses of operating a steam turbine-generator system at its controllably selected pressure and temperature. Specifically temperature and pressure signals are generated at various points in the system along with the control valve position signal and the electric output signal from the electric generator. This data is processed along with the corresponding design values and the economic losses due to temperature deviation, pressure deviation and exhaust pressure deviation from design are calculated. Other calculations produce a comparison of efficiencies of the turbines in the system and consequential power losses.

摘要： Quad-redundant signal processors in a flight control computer control valves to modulate airflow in a circulation control rotor system. The valves are arranged in a series and each valve is responsive to two signal processors. Loss of a valve occurs when both signal processors for that valve fail. A first valve, and every fourth valve in the series thereafter is responsive to a first signal processor and a third signal processor. The next valve in the series, and every fourth valve in the series thereafter is responsive to a second signal processor and a fourth signal processor. The third valve in the series, and every fourth valve in the series thereafter is responsive to the first signal processor and the fourth signal processor. The next valve in the series, and every fourth valve in the series thereafter is responsive to the second signal processor and the third signal processor. Predetermined pairs of adjacent valves define fixed rotor locations and the pair of valves at a fixed rotor location are controlled each by two and aggregately by all four signal processors. The first and second processors are in a separate chassis from the third and fourth processors.

摘要： A fan, especially for the conveyance of the combustion air in a motor vehicle heating system, provides for adjusting of its output, with an efficiency that is as high as possible, and little operating noise. The fan, which preferably is a ring-duct fan, has a by-pass duct connected in by-passing relationship to the exit of the fan, with the by-pass duct containing an adjustable throttling member. In accordance with a preferred embodiment, the by-pass duct leads back into the intake duct of the fan.
