inlet guide vane उदाहरण वाक्य
उदाहरण वाक्य
- The engine has a 14-stage axial-flow compressor, producing compression ratios between 9 : 1 to 13 : 1 depending on altitude, also controlled by variable inlet guide vanes and blow-off valves.
- The gas is accelerated to supersonic velocities within the tube using a De Laval nozzle and inlet guide vanes spin the gas around an inner-body which creates the " ballerina effect " and centrifugally separates the water and liquids in the tube.
- The engine compartments consist of an eight-stage axial-flow compressor directly coupled to a two-stage turbine, a through-flow annular combustion system, variable inlet guide vanes, controlled compressor interstage bleed, exhaust nozzle and accessory drive system.
- In turbocharged engines, EGR needs a controlled pressure differential across the exhaust manifold and intake manifold, which can be met by such engineering as use of a variable geometry turbocharger, which has inlet guide vanes on the turbine to build exhaust backpressure in the exhaust manifold directing exhaust gas to the intake manifold.
- The Sapphire compressor operated well, free from surging, over its complete RPM range without the need for variable inlet guide vanes ( VIGV ) or bleed ( VIGV on early engines were fixed on the "'ASSa . 6 "'. ) However, early compressor stages suffered from fatigue due to rotating stall at low RPM and various fixes, such as lacing wire, were incorporated.
- Beyond about 5 stages or a 4 : 1 design pressure ratio a compressor will not function unless fitted with features such as stationary vanes with variable angles ( known as variable inlet guide vanes and variable stators ), the ability to allow some air to escape part-way along the compressor ( known as interstage bleed ) and being split into more than one rotating assembly ( known as twin spools, for example ).
- The initial " T700-GE-700 " is an ungeared free-turbine turboshaft, with a five-stage axial / one-stage centrifugal mixed-flow compressor, featuring one-piece " blisk " axial stages, with the inlet guide vanes and first two stator stages variable; an annular combustion chamber with central fuel injection to improve combustion and reduce smoke; a two-stage compressor turbine; and a two-stage free power turbine with tip-shrouded blades.
